Well I have been working on a Bitx40 TRX for around 2 months now on and off. Well mostly off to be honest.
When I got it,it would not transmit. Two faults I found. One was my doing as I didn't understand that the PA had a separate power supply rail but the second one was a poor solder joint on the bias pot. So soon had it working but only 2 watts and not as stated 7 watts.
