Re: LF: JT9-1 questions

[Chris Wilson <dead.fets@gmail.com>]

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 :)
