Hi

Welcome to the group :-)

My Arduino UNO also uses a CH340 USB to TTL Serial chip - typical of cheap chinese clones - and I have never had a problem. Since your UNO works correctly with the Arduino IDE it should work fine with the G8JCFSDR.

Also I don't recognise the error message you describe. Could U please run the G8JCFSDR in TRACE mode and email me the logfile to help me understand what is going on ?

In G8JCFSDR, U need to select the Serial I/F tab under config, and then select the correct COM port, set baudrate to 115200, 8 data, 1 stop, no parity.

A really simple way to test the connection is to launch a terminal emulator, eg Tera Term, PUTTY, and connect to the UNO using a serial connection. Typing V<enter> into the terminal emulator should result in a response of 1.2 or 1.3 depending on which build of G8JCFSDR you have installed. If U can't make a connection into your UNO from the terminal emulator, then something very strange is going on, eg incorrect COM port, another program has the COM port opened already.

Please let us know how you go.
