Re: U3S transmitting- how to troubleshoot

Picking this up again. Hans- thanks for the rev5 instructions- I just missed seeing them on the page.
Ryan- I worked my way through the continuity, I don't trust the job I did soldering my antenna coax braid to the board, so I replaced it with a connector. Cleaned up some other joints too. Most notably, I adjusted the bias. I don't think it's perfect, but it was obviously at the 'wrong' end.
So, at a theoretical 100mw, I'm getting some pings. Not as many as I get with the WSPRlite at 200mw, but more than zero is a massive improvement.

The jumpers look fine, Ted. Get an LPF into position 1, or else use a wire to jumper in/out together, and then test continuity back from the antenna connector :)
