N1BUG would you share your 2200 meter amp design? I had my Mag loop up
catching your WSPR until I moved shack to other side of house. Will be back
listening this weekend again. Anyway attempting to join the TX side.

Thanks to all who ran grabbers and sent screen shots during last night's test.
This was an experiment to see how the little amplifier would hold up at 200+
watts output under higher duty cycle and to see whether my CW ID would be
visible on grabbers.
The amplifier did fine. Efficiency was down a little this morning because a big
drop in temperature overnight drastically lowered the antenna system
resistance. I didn't bother going outside to change taps on the transformer.
I did not see any evidence of the CW ID even on grabbers where my signal was
quite strong. Next time I run this test I will reduce the speed of the ID to
see what happens.
I am behind on email. I need to get a little sleep now so I will remain behind
a bit longer. :)
When I wake up I plan to make a few changes to the transmit converter. If
successful, I hope to be QRV for JT9-1 and JT9-2 QSOs for the next few nights.
No promises yet. If not successful the worst result could be a ded FET and a
fuse. That's about $1.50 cost plus 20 minutes to repair, so I'm not worried
about it... ;-)
