No SSB output

Tim All Messages By This Member #33574 PTT working, it goes into TX and amps increase, relays click. I2C checked out on all but BPF which I am using 3rd party BCD to control. Audio hat works fine for RX. Tim? ?
Oliver KI3P All Messages By This Member #33573 Are you certain that your PTT button is working? You should hear relays click when you press it. If the PTT button is working, then a lack of signals out of the audio hat implies that the hat is not working for some reason. I'm assuming that the I2C connection to the audio hat did not have a fault on the BIT screen at boot?

Oliver KI3P All Messages By This Member #33566 Yes they are. Step through the circuit starting at the audio hat. Do you see the 750 Hz audio tone on the I and Q outputs of the audio hat? Then, walk through the transmit chain on the RF board and find where the signal disappears.
