Ken My experience is very similar. My 3/8 wave GP - 160 ft tower, 15 ft mast - is fed at 32 feet with 5 radials. I saw a very minor increase in signal with radial #4, none with radial #5 checking wit

Tom, please don't stop there. What was the dollar spent on?? Did you get rid of the 775DSP? My 781 probably uses a similar scheme but, except for crossband like JA, I use RIT/TIT for splits under 10K

I think you'll be happier with the 775. The R4C has relatively low dynamic range and TOI compared to today's transceivers. Get competitive with it (ie, contesting) and it'll fold early. But, has real
