PTT over CAT in WSJT-X no function, does not transmit in FT8

 

开云体育

Hello,

?

my QMX is working now. I didn't have to adjust anything on the band filters. On all bands, the transmission power is about 5W in CW. The sensitivity in FT8 is good and significantly better than with my QDX. An interesting module is the SWR bridge. It protects the PA from mismatch. The QMX only achieves full performance when the antenna is tuned.

My device still has a problem. It does not broadcast in FT8. If I tap the PTT button in the configuration of WSJT-X, it lights up red. There is no signal on the antenna when transmitting. Does anyone know the problem or is it a firmware issue?

Reinhard,

Possibly PC configuration? /g/QRPLabs/topic/100624101#108489

The PTT test does not put out any power. It's just tests the control lines.

Set the "power" slider in WSJT-X all the way up. In the digital mode the QMX is not modulating SSB. Its doing true FSK, based on the tones on the input. If they're below the threshold to decode, there's no output.
