2) *_AFSK is being regularly produced by WSJT-X through the computer sound card_*, then I guess that there is a sort of "*/software muting/*" of this signal which is blocked in some way to feed the rear data connector of my YAESU FT-100 which in turn doesn't transmit any RF. May be if I would attach the AFSK output directly to the radio mic plug, then the RF transmission would be possible.

Hi Marco,

This a wild guess as I have no access to YAESU FT-100, but in some rigs you need to select Mode Data/Pkt not USB in order to get audio via the rear data connector.

Yeah Jarmo!!!

You are right, in fact yesterday I was playing around the modes and I verified that if I select digital and set accordingly my FT-100 menu to use "PCT_USB", then my environment works: AFSK reach the rear data port and my FT8 signal is being transmitted.

However I guess DIG mode is not ideal for my setup because it looks like nobody is answering to my CQ's (tested some minutes on 40 meters band).

I will try again today the DIG mode on the higher frequencies, where is more easy to get a station reply.

Best regards
