WSPR 2.11, build r2250 works fine with my FT-817nd and my HP laptop via a CT62 USB interface lead but I cannot get it to work on my Acer Aspire One with the same hardware and software. I am using the same program settings (with the com port number set accordingly).

The message window reports "Error executing rigctl to set Tx mode.....".

(See attached image)

Can anyone offer any ideas?
