I am having this same issue with RTTY on my low band QMX, firmware level 014. WSJT works fine with FT8.
- fldigi attenuator IS set to 0db (saw the pointer on YouTube about that)
- audio out is 100% (before that change, there was not tx at all)
- I doubt I have changed rise/fall times
- I doubt I have changed minimal samples from the default
- I am sure TXID is off.
I do see transmit bars on the QMX, but only for a seemingly random, typically very short (1s or so, but as much as 6s) transmissions. My macros DO set it back into <RX>, but I would have thought fldigi would not send that until it was done transmitting the text in the macro?
