I had similar problem some time ago. No Tx.? I could hear K1 pulling in but in actual fact it wasn't making contact. I replaced it with a different brand of relay and no problems since. But it does make me suspicious of the other relays in the uBITX. If they don't work then? a LPF may not be actually switching either.

Yay! K1 was indeed bad, I now have a working receiver and transmitter, however the output power is only 500mw compared to the 12 watts before. Do we think the IRF510's are shot? What would be the best way to check them or should I just replace them, I have plenty in stock.
