If it is the wrong place to ask then why did you do it? Just spit out your question without apologizing. Another snow flake? I guess it is better to ask for forgiveness than to ask for permission. Do

Hi All, I see quite a few members of this group asking about exciters, amps, antennas etc, so here goes:- I'm active on 630m, usually WSPR but also JT9 and FT8. I had been active on 136khz and I am b

I use the Elecraft K3, it outs out 1MW via the transverter interface, that drives a single MOSFET amp easily. Antenna I use my 160m InvL 70 up 70 out with a large variometer to tune to 475khz, tap th

Get a Central Electronics 10A. Plug in coils and be will work with 2.5 mh chokes and tune 455 ok. Real simple. Use an old 6 mtr crystal (8527). Just off the shelf stuff. Colin K7FM __________________

Good question Jim, dont know if they are still available. I rarely use it as I have a low freq coupler for the LP-100A I find it more useful as it will measure low power as well, Merv K9FD/KH6 <I was
