Working Falconsat-3 with hardware TNC is piece of cake. compared to combination of multi-software to read data and keying the rig .

TX LINE -WISP-> HW VSP-> SOUMDMODEM -> 9600 DATA --> Keying circuit

I succeed to upload a message to FS-3 .
 Also got the "NO -5" errors.when I requesting the Dir.

Other problem during handshake, the transmitter noise desensitization (desense)  the SDR receiving signal . (instead dozens  ferrite choke on every wire and coax ). All equipment has a decent earthing too.
