Hello DK7FC, JT-9 on hold as I can't find the plug for the TX signal out of the TS-590, I had forgotten that I needed to make a lead to the antenna change over box. I tried a couple of TX only sessions from the U3S but it was more experimental than useful as receiving meant very rapid BNC changeovers. Will do some WSPR2 tonight, although the band looks quiet. I have got the photos of the bridge amp, very useful, will collect bits! Could the choke wound on the iron core of a transformer be wound on a scrap mains transformer toroid instead Stefan? Thanks for the high res photos, they are a big help. The question re gate and drain waveforms was to Paul N1BUG though, about his antenna? troubles :) Wednesday, December 5, 2018, 7:39:21 PM, you wrote: > Hi Chris, > Try something below 137.400 kHz and above 137.200 kHz. > I will watch for you. > 73, Stefan > PS: Did you see me last reply email? -- Best regards, Chris mailto:[email protected] |
