Hi all. I received my second BitX40 a few days ago (the original design with the veractor not the dds) hooked up the necessary wires to get it receiving an all worked ok. I had been playing with the receiver for a day or 2 comparing it with a TS830s and it seemed to work very well.
Then I decided to hook up the microphone, I connected the ptt line but not the audio input. I clicked the ptt to check it worked, there was a quite loud pop in the speaker and when it came back on RX the Bitx40 is now quite deaf. Band conditions have been poor here and there were not many signals to listen to, but ones I could just hear on the bitx were s9 on the ts830s. Has anyone else had the same experience and could point me in the right direction as to what part of the circuit is the most likely area I need to troubleshoot.
Thanks in advance
