TS590 tcxo, WSJT-X multiple instances and dx!

I have been trying out the TS-590 and I seem to have caught the dx bug, working all round Europe and into the US on 40 metres. This short wave radio thing is quite habit-forming.

I have fitted the tcxo (temperature compensated crystal oscillator) into the Kenwood TS-590.
The SO3 tcxo for the TS-590, along with the supplied adjustment tool and a £1 coin for scale.
It takes 100 of those pound coins to buy one.

For such a tiny thing, £100 seems rather a lot, especially as the rip-off eBay tcxo-alike costs about £10. And you even have to solder the Kenwood one onto the board yourself, while the £10 one comes already soldered onto its own replacement board.

I think that leaving the tcxo off a rig like a TS-5900 is a bad move. The cost of designing in a separate small board, screwing it in place and providing jumpers, then selling the txco separately all round the world, with costs of transport and the cost of storage plus financing at the dealers ... I guess that just putting it on the board to start with probably might cost under £20, and then 100% of rigs would have it fitted as standard.

I suppose not everybody uses WSPR and data modes as I do. Ah dear. Hard to comprehend, I know.

Anyway, you take off ten screws and the bottom case, unscrew the mini-board and unplug it, get the tcxo the right way round, solder it in six places, screw the mini-board back in, plug the board back in, take off two jumpers, and use the ten screws to get the case back in place. In manufacture this would just be one component amongst dozens inserted at the same time.

OK, rant over.

It works perfectly as far as I can see. They supply a little plastic dibber to adjust it for correct frequency (no doubt that bit of plastic makes up a large part of the £100). So far I have not adjusted it. I did a comparison with a couple of WSPR operators who are famous for being scrupulously accurate. On 40m I came with in 2hz, on 10m within 3hz. OK, I could fire up my GPS frequency standard, but the setting recommended by Kenwood is by ear. I doubt if my ancient ears can do better than the WSPR result. Eh? What was that? My ears do what?

Which goes to prove a couple of things. First, 10m was open! Yes, a burst of Es yesterday allowed me to do the WSPR tests on 10m. Second, 6m was not open, so that will have to wait. It would be better to test the 5th harmonic of the GPS standard against the TS-590 on 6m. I bet it will hardly matter. I have two requirements:-

1) the rig should not drift on WSPR to any great degree, and
2) it should start each time pretty well on the right frequency.

More tests needed eventually but so far both of those boxes appear to have been ticked.

Things are not so rosy on the WSJT-X multiple instances front. Changing the computer for a faster machine has made things just a little better. I can run two instances of any other mode just fine, but two instances of MSK144 is too much and the display starts to be compressed. Whether that has any effect on the decoding I have no idea (but I doubt it).

The faster machine helps, but does not solve things completely. I can even find some shortening on just one instance of MSK144, variable, but usually only about half a second.
This is with one instance, different computer, different rig and a fresh installation of software.

I have done a lot of comparisons. I will leave them all out of this blog. My conclusions are that my initial idea was right. I believe this problem arises because only MSK144 has real time decoding, which demands a lot from my processors. Changing the computer over made very little difference, as I was adding memory and faster handling at every point, but the processor speed is much the same.

My initial work-around of using MSHV for one of the instances still works. I can just stick with that arrangement.

There cannot be too much wrong with it. I worked some DX on 6m MSK144 tonight - GI4DOH, almost 250km away. Meteor scatter too; it took 45 minutes to complete while we waited for the pings. My first meteor scatter contact in IO74.

Do you know, there is something about amateur radio? I hope to turn the rig on and try a bit of 40m action around midnight. What will conditions be like? There is still that moment of expectation while I wait to hear who has heard my CQ. There is still the puzzlement of trying to work out if I have worked this place (... DXCC, square, state, oblast, island, station ...) before.

You can cloak it up in all sorts of modes and CAT defined frippery (and I do), but just working some interesting stuff is reward enough. For me, it always has been.

But you knew that already.

See you all on the bands.

TS590 climb down, and WSJT-X 1.7.0 outrunning my PC.

"Oh Lord, it is hard to be humble
when you are perfect in every way"

So sang Mac Davis many years ago. I have to agree with him of course. I am not quite so sure about the next bit of that song.

"I can't wait to look in the mirror
'cause I get better looking each day."

Anyway, it is so hard to admit to imperfections (especially as I am so close to perfection almost all the time).

There are a few things in my life which, on reflection, I might not have done the way I did at the time. That is, knowing what I know now.

I suppose, to mention a few, I could have done without getting robbed at gunpoint. Or maybe I could have handled it better. I was careless enough not to take notes about the gun, as the police asked me to describe it later. And then there was getting my upper jaw broken. I might have been better taking the ambulance to the right hospital, rather than getting taken to the nearest one by car. I did not want to travel in the same ambulance as the woman who caused the broken jaw, so I took a lift instead. At the nearest hospital they called out the duty dentist who tried to stitch together the two bones by trying to hammer a needle and thread through the upper jaw bone. Having a needle hammered in the roof of my mouth was painful. He bent several needles before he gave up. I think all the broken teeth were getting in the way, and the bone wasn't fixed of course. You cannot stitch bones together, nor hammer through solid bone, or not easily. I should have had the composure to point that out to him.

They had to break the jaw again later and re-set both parts. So while my upper jaw was wired to my lower jaw as a splint for 6 weeks, I could not open my mouth. CW only for 6 weeks! What a joy.

Surely then I have to admit that everything in my life has not been perfect, and there are a few things I might have done differently. Like not breaking the jaw in the first place, or not getting knocked unconscious on a different occasion.

There are other things, but they are far more gruesome and therefore not to be mentioned here.

Yes, despite my near perfection of judgement, not everything in life has gone spiffingly.

So I can now admit that selling the Kenwood TS-590 3 years ago was not my greatest judgement call. I was young and foolish. So, given a bit of prompting lately, I have bought another one.

I will report on the TS-590 later. This one is second hand, but very low mileage. It is a TS-590SG, which has a few tweaks compared to the 590S which I had before. The differences are slight, but they all seem to be useful for me. Maybe that is why I changed the 590 for a newer one.

It was quite a struggle to get the CAT control to work, but finally after a full reset of the rig and changing the port settings over to "Hardware" handshake everything started to work.

First observations are that it works beautifully. The receiver is a joy, as you might expect looking at the specifications. For the type of operations I do it needs the optional TCXO oscillator as it seems to drift quite a lot on 6m after switch on. For normal SSB use this would not be such a problem, as we are talking about 100hz or so. We shall see whether the TCXO does the trick.

I have been warned off cheap TCXOs being sold on eBay. It seems that they generate a lot of phase noise. Going onto YouTube I found an interesting post showing someone carving up a generic eBay TCXO. It looked like a crystal oscillator with a frequency divider. I could not see how it was compensated, and it performed badly compared with OCXOs. We will see how I get along with the official Kenwood one when it arrives. I am not against adding an oven as well, if I need to, but let us wait and see.

Will I regret selling my FT-450? Maybe because there was nothing wrong with it. I have not actually sold it yet but it is on eBay and I have a bid, so it will sell in due course. What it lacked were the transverter sockets, plus it is generally a much lower-specified rig than the 590. Very good value all the same and it came fitted with a tcxo.

So there you are I have admitted to my mistake and corrected it.

Hey, now that I am not claiming to be perfect, I do not have to follow the song's theme and it should be easy to be humble now.

No, I think I will give humility a miss. Where is the mirror so I can admire myself?
WSJT-X 1.7.0 is a great thing, but it is running rings round my computer.

I have mentioned this before, but I have now examined things more carefully.

Here are two plots showing the received signals, both running simultaneously, receiving noise on MSK144 mode. The top one using MSHV, and the lower one is using WSJT-X...
They are both set, of course, to 15 second receive segments. But if you look a the lower of the two traces on each, MSHV manages to fill the 15 seconds time with received signal, whereas the WSJT-X one stops short at just over 12 seconds. This is strange, as the received audio was timed by me at exactly 15 seconds in both cases.

It is the same with the both rx segment traces. I could not quite get to the full 15 seconds on the upper ones as that would have cancelled the trace, but on MSHV I was getting almost all the way to 15 seconds, whereas on WSJT-X I could only get to just over 12 seconds again.

So the WSJT-X trace only gets to around 12 seconds along, even though this represents 15 seconds of recording. It seems to me that either the software is missing the packets or it is not displaying then. The timing cannot be wrong when the tx/rx switching is happening at exactly 15 seconds every time, whatever the display shows.

The situation gets worse if I increase the load on the PC by, say, widening the FTol to 200, and it gets a bit better if I reduce it, such as by reducing the decode depth. The load as shown on the processor varies between 40% and 80%. Setting FTol at 200 pushes it to 80% most of the time.

It is pretty clear to me that WSJT-X 1.7.0 puts too much load on my processor, whereas MSHV, which does not load the processor so much, does not.

This effect is present when I only have one instance of WSJT-X running on MSK144. It does not get worse if I run several instances running WSPR at the same time, but it does get worse running two instances of WSJT on MSK144. Leaving the multiple instances issue to one side, and only running one instance, WSJT running MSK on its own has this problem. If I close down any processes and lighten the load on the processor, the trace goes further along the graph, if I increase load the problem gets worse.

I doubt very much if this is actually affecting the processing of WSJT or the decoding of signals. I guess it is just the display which is getting behind. Nevertheless, it is not a good sign, and the PC has crashed a couple of times for no good reason other than it was using a lot of processor capacity.

The actual PC display goes through a separate IDE display board intended for gaming with its own processing on board. I doubt if that can be at fault as the MSHV display is fine.

This computer is no slouch. Well, not by the standards of a man who once owned a Sinclair  ZX81. It is an ASUS board with Windows 10 Pro, AMD FX 4 core processor running at 4.2GHz, fully loaded with 8Gb of RAM. I have added 4Gb more space using Ready Boost and a USB flash card. I think it has gone as far as it can go, and the basic problem is that the machine was never configured for speed. It was always intended as a general purpose computer.

So I am working on transferring in a machine used for video editing, which has more RAM. Having been built by me originally using gaming standards it was generally built for speed. I think its weakness is in the disc transfer speeds but let us see how I get on with higher processor capacity.

Buying the TS-590 and the TCXO has emptied my wallet. I need the TCXO as the TS-590 is not stable enough to turn down the FTol on WSJT, and that in turn is overstressing the PC. The two issues are linked.

I do not think that WSJT-X was specified to require a gaming computer to drive it. I fancy that this is exposing some overall weaknesses in my general "office" computer. But nevertheless the arrival of the TS-590 and WSJT-X, and my ever-increasing processing demands, are all pushing me into investing more money. So paradoxically, I cannot now afford the 2 metre transverter, which is why I bought the TS-590 in the first place.

I might just go back to an FT-101E. Never had issues like this then.

2 metre rig and WSJT-X roundup.

Thanks all for the various postings and e-mails lately.

Firstly, regarding the 2 metre rig saga in my last posting (link here)

Gav, GM0WDD, you are quite right, plus you have hit upon the dark secret I have here. I used to own a TS590 and a 2 metre transverter. Thus I have an issue about facing up to what looks like a crazy reversal of direction on my part. That was 3 years ago and the TS-590 has had two revisions since then. Can you see me trying to justify buying another one? Was I hiding a past mistake?

I have been "outed" now and I can come clean. Yes, I sold my TS-590 and, yes, I regret it now. If I still had it, this conundrum would have been solved by now.

My experience of the TS-590? I thought it was brilliant. Maybe not quite competition grade performance, but then not competition grade price either. How come the rigs I used to own always look better in the rear view mirror than they did when they were on the bench?

The way I used it with the transverter and an SDR depended on the transverter. Either I put a T-piece on the receive line (on 2 metres), or when I used the M&E transverter I could access two rx outputs from it (on 4 metres). Either way there was plenty of gain on both rx paths to share the receive output of the transverter.

You are correct that the option of adding an SDR to the TS-590 can only be done if you are not receiving on the same socket. So if I wanted a spectrum scope for 6m I could (I think at 3dB loss), and for 2 metres it is easy to do with a transverter, but to do them one after the other without plugging and unplugging is tricky.

David, GM4JJJ, thanks. I feel sure that 2m SSB and Data can manage without me for a while. Coming off 2m has really cleared the air here. Simply by re-organising the rigs and antennas I can see more clearly what needs to be done.

I am interested in your point about a poor setup being better than nothing. I think you have put your finger on it being about ergonomics and personal taste. I am now more focused on the problem - what does 2 metres mean to me and to what extent am I committed to solving this problem. I have gone to some length to re-instate everything else, HF, WSPR, 6m (4m is unchanged), yagis refettled, verticals swapped about ... but 2m just fell off the end of the plan.

Much as I would like to be the MSK champion on 2m, I do find 2m meteor scatter operations to be dominated by FSK441 and pre-arranged QSOs. Calling CQ on MSK was pretty unrewarding (entirely unrewarding in fact).

So I have taken the chance to go "cold turkey". No 2m SSB or Data. If I had left things as they were I would never have fixed any of it. I suspect that once I come to rebuild things they will involve new ideas. Starting again from scratch looks like the best plan for me. I might still be using the IC-7100, but mainly for the lack of a really compelling 2m rig to replace it.

Yes, it was pretty windy. Was it the same gust which blew over the HGV (semi-trailer) on the Forth Bridge which wreaked havoc here? Probably not, but I will never know as the cups on my wind speed gauge have been carried off in the gales and are now in Heligoland, no doubt. The antennas survived with much flapping and bending. Our greenhouse door blew open and six panes of glass got blown out. I managed to reuse one, but replacing the others involved Mrs FVM and I working in a freezing environment in the middle of the gale. If we had not acted the rest of the panes would have gone too. Terrific fun.

Officially it was max 110km/h gusts here. Only 102 is expected tonight, so we should be fine now(!)

Secondly, thanks to Bill, G4WJS, for his comments here on WSJT-X.

I now have multiple instances of WSJT-X running. However, I still cannot have two running MSK very well together. I suspect this is due to lack of processor power here. What happens is that the Fast Graph trace gets shorter and shorter, sometimes showing just 10 seconds of signals even though they appear to contain the full 15 seconds of data. I can correct this by reducing FTol or decoding depth, or by simply turning off one instance. Running one on WSPR and one on MSK is fine, or some other combination including JT65 or JT9, but of course WSPR and the other modes do not use real time decoding.

This is not a big issue as it is easy enough for me to run MSHV for one of the MSK monitors. Sometimes that still leaves the trace about half a second short.

I can see that the way WSJT-X handles split is fine. I was just not used to it, and I got confused at one stage. I suppose that using another program at the same time which works the other way round is asking for problems. Still, I keep doing it.

So thanks for all the contributions and if you live in this part of the world, enjoy the wind and snow on the way.

Where is the good 2 metre rig?

Greetings all, I have been reshuffling, as I so often do.

I tend to work out what is the limiting factor in my station and try to deal with that first. So it could be co-ax, it could be height of antenna, it could be rig or it could be software or computers. Gradually I have got on top of most of the issues and I am pretty happy with the general shape of things.

We now have superb aids to communication. WSJT-X, for instance, or SolarHam, DXMAPS, or real-time magnetometer readings. If we cannot anticipate conditions, at least we can manage them to our advantage.

When it comes to transmitting hardware, there is one band which troubles me. Good old 2 metres.  2 metres was my starting point in amateur radio transmitting, over 40 years ago. My good old EMSAC TX2, with its QQV0-320 valve in the final glowing purple, got me all round London in my early days. Since then rigs in general have improved out of all recognition, but 2m now seems to be a forgotten area.

A few years ago I borrowed an Icom IC-910 to see how it felt to use a modern purpose-built VHF rig. I hated it. It was noisy and apart from having a high power output, it did not really offer much more than the transverter and HF rig I had at the time. I had it for three or four months, during which I worked my best DX from here (into Belarus), but that was all it had to offer.

After the IC-910 went out of production there were no purpose-built VHF rigs left on the market. Instead, if you want to use 2m SSB you have two alternatives:-

1) use an HF rig and a transverter, or

2) use a multi-band rig with VHF.

Option 1 is well tried and tested by me. In the 1970s I used an HF rig and an SSM transverter. It had a QQV0-640 in the final and it ran 80 watts - which was pretty impressive at the time. With my FT-101E it performed very well. I must have had 10 transverters over the years.

The idea behind a transverter is that it both converts your transmitted signal up to VHF, but it also converts the received signals back down and presents it as a tuneable intermediate frequency. This allows you to do things like install an SDR receiver into the receive line and get a panoramic display of the band. That was pretty well the set-up I had for 4 metres until recently, latterly a Flex 1500 transceiver with an ME4T-Pro transverter, and a Fun Cube Dongle for good measure. I still have the ME4T-Pro as a back up.

The joy of this set-up is that the transverter can designed for just one band, with optimised filters and lovely low noise mixers. The results can be brilliant when using a really good HF receiver. Usually the IF is 28 to 30MHz, though 14 to 16 MHz might suit me better as I use 28MHz a lot. In fact, just such a transverter exists in the shape of the ME2T-Pro.

Option 2 seems easier. Just buy one of the all-in-one rigs which cover 2 metres.Simple. Except that it isn't obvious what to do to get value for money. I already have one of these, my IC-7100. it is fine for FM and D-Star on 2m but it is not a great 2m DX rig. Let us face it, it is a mobile rig.

There are several of the IC-7100 type rigs around, (for example FT-857, FT817 and the former FT-897). It is very convenient for someone who is principally an HF operator to use one of these to chat to their friends on VHF or even UHF. For repeaters, great. For DX, well I am not thrilled by this type of package.

So what I think I want is a better receiver and transmitter boxed up with good VHF performance. The answer to this is the IC-9100. This takes the performance of several higher-grade Icom products, and merges them into the concept of the IC-910. It has been said that it is an IC-910 with an IC-7410 on the HF end. So what is the problem? £2,800 is the problem. I am sure it would give me excellent performance, but the price is eye-watering.

This challenges my whole approach to amateur radio. I do not want a big expensive rig, I want several to tinker about on several bands at once.

Then if you take one step down the ladder you find a rig less than half the price of the IC-9100, the Yaesu FT-991. This rig had a doubtful start, with many reports of poor performance and burned out finals. Once these issues were sorted out, the later models seem to get good reports. With the latest version (991A) you get a real-time spectrum scope (though the previous display looked good enough to me). Price £1,200, and now offered with a three year guarantee!

The FT-991 is not a competition grade rig like the IC-9100. Nor is it a mobile rig with bolt-on VHF. It fits in the ultra-competitive bulk market where I like to buy my rigs. Price competition and volume sales in this sector mean you get good value for money, at the cost of losing the up-market fancy stuff. The FT-991 is dogged by memories of its unreliable start onto the market and suggestions of excessive phase noise on its transmissions. Has all this really been sorted out?

What I would like is something half-way between the two, improving 2m performance but still affordable. And ideally, not something that covers aircraft bands and FM broadcasts, as including those things tends to weaken performance on 2 metres.

Other rigs in the HF + VHF segment all appear to be old designs or flawed in some other way.

So there we have it ... transverter, or really good expensive rig, or a rather doubtful general purpose rig?

I am just going to leave it for now.

All I am trying to do here is to improve on my current 6m/2m rig, the IC-7100. Good as it is, it does not do 2m justice for DX, especially with the limitations of my site. I want a rig for those bands which does a bit better than a mobile rig. Then I will probably find out that the rig is not the limiting factor for 2m after all.

How important is this for me? Just to prove that 2m DX matters, I have taken down my 2m yagi. I have moved the IC-7100 over to 2m and 70cm FM (and D-Star!!!), plus occasional forays onto HF where the FT-817 lacks power. The FT-450 can do 6m for now.
The IC-7100, at home on FM, but on a higher frequency than it is used to
So I am going to sit it out. If I pine for 2m SSB  I will do something about it. If I don't miss it, then so be it.

I am all set up. All it will take will be for me to replace the FT-450 with the right combination for 6m and 2m. Or, maybe, just leave things as they are.

Meteor scatter software developments, Xmas propagation, and HNY.

First of all may I wish you all a Happy New Year.

May all your DX be far away, may all your antennas be well supported, and may the transistors in your final stage stay cool and efficient.

Oh, and may your power supplies keep going. My MyDel 50 amp returned two days ago and is now back in service. With no circuit diagram or component list I had little to go on, apart from working out that the buzz suggested to me a failure in the switching circuit.

Then John, G1VVU ran his eyes over it and delved into the surface mount components on the driver board. John had in his mind the circuit of a much older MyDel unit which suggested two transistors in the driver board might be at fault. Sure enough his hunch proved correct. He ordered two bcx54 devices, guided by the specification on the old design (which were 2sc2313), but in the case sot89 to match the faulty ones. And it worked. Component replacement cost £2.07 or 1.5% of a new PSU.

This just highlights how much at risk we are with surface mount devices. Me, never having worked in the electronics industry, and not having a single qualification in that area, was completely lost. Not only are the devices all looking strangely similar, often they are not marked with anything meaningful, and too small to work out what they are.

In days of yore amateurs would have built their own equipment and changed individual components. Now we are operating at the level of changing entire power supplies. Happily not mine though. It is working again until something else gives up the ghost. Great work John, thanks.

John was fairly sceptical about using this power supply at the full 48 amps I might need to drive the 6m linear. True, but I cannot find any other way of generating 13.8V at that sort of current which is both affordable and fits into the shack. Anyway, in general use it only draws a mere 32 amps (!) at the output power I tend to run.
Moving on, Xmas brings the RSGB Christmas Cumulative Contests. I have taken part in these for some years. There was Sporadic E all around the times of the four day contest, but none for me during the actual contest periods.

In fact, since I reported on the Es opening on 26 December I have completely missed out on various Es openings. I can hear other stations in G and GM working stations I cannot hear. I have been a bit unlucky, but that is what you can expect on Es. Sometimes you win and sometimes you lose.

There was a little bit of tropo on the 2m part of the contest on 27 December.
2m contacts at GM4FVM on 27 December 2016
Goodness! F6DBI!

After all my fulminations about how I cannot work south from here, I managed to work France on 2m tropo! I have only worked France on 2 metres once before from here, and that was a meteor scatter contact with a station almost far enough away to be on the border with Spain. But France had never been done by me on 2m SSB or tropo before.

Well, it did take 8 years to do it.

I am not about to revise my views about the rather large hill outside the window. It does block me to the south and east, and if you look at the map above you can see that this particular station was west of south. I know that I can work along that path into Devon, so this cannot come as too much of a surprise.

I was actually trying to find stations round the side of the hill when I heard F6DBI.
All-time squares worked on 2m from GM4FVM
If you look at my all-time squares worked from here on 2m you can see a pretty definite pattern. This site definitely favours the east for dx working.

Mind you, 2m has never been my favourite band and I guess that is partly due to that hill. Perhaps if I tried harder I would do better. On the other hand, I think I can see the shadow of the hill, stretching from the Isle of Wight to the Pyrenees, and from Belgium to the Alps, plus everywhere in between.

Hey, look on the bright side Jim. Now you have worked France on tropo. Even if you ignore the shadow of the hill, there is still all the coast down to the Bay of Biscay, and all of Spain as a possibility.

While I have been busy reporting on WSJT, MSHV has been revised several times.

We have now reached v1.31. Recent additions include the ability to double click on callsigns and reports to enter them into the tx messages. Also, v1.31 includes three additional measures of MSK144 signal quality. These are "Navg", "Bit err" and "Eye", new macros for contest exchanges and RX equalisation selections (off, standard, dynamic, and standard +  dynamic).

I am not exactly sure how all of these will pan out as I have not had much chance to try them.

So why, if everyone is so taken with WSJT-X 1.7.0 am I still persevering with MSHV?

Well two main reasons:-

1) MSHV uses a lot less processor power, and
2) MSHV has the only route I know to run FSK441 and JT6M with CAT control.

As I run two or three rigs at once I could easily overstress my PC with various demands, so something lighter helps. As for FSK441 and JT6M, well my view of those modes is well known. I do not like them but until they die out I need to be able to summon up MSHV.

But there are less significant reasons for using MSHV. Unlike WSJT-X it does not changes the frequency of the rig without me knowing. Yes, it is great on WSJT to change band and mode, and even rig, without touching them, and to have everything done for you. But somewhere you lose control and I am yet to be convinced that I can avoid some terrible mistake while I was on autopilot.

The automation in WSJT is a joy to watch, but you still need to show it who is master.

Speaking of which, this may well be my latest piece of confusion:-
Above is WSJT with its QRG setting, which you set up by setting your receiver on the rig dial and selecting which frequency you wish to Tx CQ on: and
Above this time is MSHV, which you set up QRG as to where you are going to RX and then TX that on the calling frequency, using the split control on the rig.

In practice the two systems work in an opposite sense. With WSJT, you enter where you want to call CQ and as you turn the rx frequency on the VFO the entry on the CQ lines changes with the VFO dial ... whereas on MSHV you enter where you are going to Rx, not where you are going to Tx, and that sets up the Tx line message.

As they used to say on the marvellous Tv 1970s series "Soap", starring Billy Crystal and the superb Robert Guillaume as the butler, after their long explanations of the plot so far:-



Yes, I got WSJT back to front this week. Have I got it right now? Hard to tell as my USBs all failed today ... and the IC-7100 had to be re-set and ... well, I will let you know.

Thanks to David, GM4JJJ, for pointing out my confusion (but I couldn't get it work either way, which really threw me off my path). I will try again later.

This never happened with the FR50B/FL50 combination.
Have a great 2017 everyone, and calm down, it is only a hobby.
