Quadrantids meteor shower marks the end of the season?

3 January 2018 marked the peak of the Quadrantids meteor shower. The Quadrantids also mark a break in the procession of the main showers in the Northern Hemisphere until April.

At GM4FVM Quadrantids 2018 produced this result:-
VHF meteor scatter QSOs at GM4FVM 30 December 2017 to 8 January 2018

This year saw me working many of the usual stations, but it felt very different. Only one QSO was on 6m, the rest were evenly split between 4m and 2m. All were on MSK144 mode. This was the first year when I could call CQ on 2m MSK144 and get successful results.

For too long now 2m operators in Western Europe have been sticking with FSK441 mode. This time I watched PSK reporter carefully and I noticed several stations working into Russia, Belarus and Ukraine. As those Eastern stations were using MSK144, the people trying to work them had to use MSK144 as well. This gave me the opportunity to be heard, and it worked. If some people want to stick with FSK441 then that is their choice, but they are not going to work me.

I did hear stations from Belarus and Russia myself but I have never worked that far on meteor scatter (though I have worked Belarus on Sporadic E). I suspect that some of these stations run quite high power levels.

Perhaps I am beginning to find 6m meteor scatter "too easy". Well, not really, but when I call CQ I can see that I am heard by many stations but few answer. So maybe they find it too easy to work me, so they don't try. I find that on 2m there are fewer stations but a lot more of them are ready to reply and try to make a contact.

So that was a successful Quadrantids campaign to round off the VHF year.

I am still left wondering whether 10m would be any good for meteor scatter from here.

Between now and April there are still plenty of things which might happen. Random tropo and aurora events can be very good fun but they are impossible to predict until a day or two before they occur. There may be several or there may be none.

The NOAA 27 day Space Weather Outlook (which you can find here) suggests no recurrent auroral activity can be expected - or at least the test of Kp index over 5 is not predicted to be met in the 27 days from 8 January. However, this predictor only really lists recurring coronal holes; a solar flare could happen at any time, or not, as the case may be.

Meteor scatter will still work of course. Just because there are no major showers does not rule out taking advantage of minor showers or background meteor action.

Plus there could be some minor Sporadic E events.

I might try some Earth Moon Earth operation. More accurately I might try listening again. My station is not well suited to EME, but it might be worth trying. There is nothing to lose. I had an email from Gordon GM4OAS which has given me a nudge towards listening again.

I had a phone call from Keith, MM6KFE, asking for a test on the local 70cm repeater GB3BE. As I had no antenna I had to try to reach him on my £8 Baofeng hand held. Not a sophisticated rig and I ended up standing in the middle of the back garden in the rain. So I have relented as far putting a 2m dipole in the loft which works (badly) as a 3/4 wave dipole for 70cms. I have managed to work Keith on that so I am back on 2m and 70cms FM for now anyway. There followed contacts with Wallace, MM0AMV on BE and Paul GM0IQI on GB3DU. Active locals! Things are not as bad as they looked.

I am quite looking forward to a lull. This has been very eventful year.
