Have you seen my rotor controller for this type of rotor? https://sm6vfz.wordpress.com/2019/12/01/rotor-control-for-spid-antenna-rotators/SM6VFZhttps://www.blogger.com/profile/13161876522136015143noreply@blogger.comtag:blogger.com,1999:blog-6891312687175550342.post-49470584283754069242020-07-05T08:30:44.206-07:002020-07-05T08:30:44.206-07:00Hi Bill. Just found your comments. The electrical ...Hi Bill. Just found your comments. The electrical noise on the SPID is the only disappointment I have with it, and that noise really causes me trouble on weak signals. As JJJ used to say "move it on transmit", but then you have to find them first.<br />I really think the SPID is a great thing, apart from that. I would also consider a Create, and I reckon that worm gear rotators must surely be at an advantage in our wind conditions.<br />I was working on it yesterday as the antennas appear to be moving slightly in strong winds. I gave the bolts a bit of a tighten. I wonder was I distorting the ali alloy pole underneath (never got round to using the steel pole I got).<br />Anyway - ground loops have been a huge problem to me in past lives. I do not do top band much and I have not noticed a sprog. That is interesting. I just get raspy contact type noise from 50 to 144MHz. Not noticed so far above or below those bands. I do not often go as low as 1.8MHz. I will have a look at some stage.<br />I know people have tried to silence it with capacitors across the motor without any success.<br />Thanks. you got me thinking there.<br />73 JimGM4FVMhttps://www.blogger.com/profile/10794029618635259984noreply@blogger.comtag:blogger.com,1999:blog-6891312687175550342.post-89094644410802832712020-06-26T06:40:21.535-07:002020-06-26T06:40:21.535-07:00Hi Jim,

However I also found it seems to produce a radio broadcast sprog on 1.818 Mhz ( mixing ?)so it may be a ground loop of sorts...any issues with yours ?<br />73 Bill GM4UBJgm4ubjhttps://www.blogger.com/profile/13219644599645326930noreply@blogger.comtag:blogger.com,1999:blog-6891312687175550342.post-54519620921988608402020-04-28T04:55:07.430-07:002020-04-28T04:55:07.430-07:00Steve

So far I just put up with it. The SPID is FAR more accurate than the Yaesu so it is much better for VHF.<br />73 Jim GM4FVMGM4FVMhttps://www.blogger.com/profile/10794029618635259984noreply@blogger.comtag:blogger.com,1999:blog-6891312687175550342.post-22993470494085119382020-02-01T13:08:34.547-08:002020-02-01T13:08:34.547-08:00a nice reveiw Jim did you ever get round to curing...a nice reveiw Jim did you ever get round to curing the noise on 6 and 4<br />cheers steve<br />G1PPAsteve PPAhttps://www.blogger.com/profile/09191707204165605099noreply@blogger.com
