Oke Boys

Here is a new TS-480SAT and I did remark the problems whith cat remote TRX and WSPR X.
first in the remote cat on a comport set the port and the transmitter on 57600 baud,
and on hardware control! , oke, then i connect the data port for the audio input and audio output
from the pc interface , so you have also set a secundairy com-port for the switch ( PTT ) to data mode on the data connector see the manual TS-480sat
This switch from the PC interface is muting the Mike and connect the data input to the audio from the TS-480sat

it works this way also in Mixway and FLDigi

Hope you have some use by this info
