Flex6500 + 70 cm Transverter

Dear OMs,

My station was off for 2 years. I used it for 70 cm EME in the past without any issue. Now I try to reactivate it. It shows a behaviour that didn't exist before.

I have a Flex6500 with SDR v3.2.39. I use a transverter (432 / 28 MHz) connected the RX A for receive and XVTR for transmit. It used to work very well.

RX A and 70 cm receive is working fine.

I'm not able to get a transmit signal out of XVTR anymore. I checked it with a spectrum analyser. No tune, no CW or SSB signal is comming out of it.

The transverter (stand alone) Tx is ok too - checked it with a 28 MHz 0 dBm signal from a generator.

My questions: Did something change in the Smart SDR Software or is it my configuration of the rig . . . ?

Thank you in advance !
