Hi Radi, I don't use PSK31, but the Prolific USB - Serial converters are known to have many problems. My first recommendation is to change to USB - Serial converters that use the FTDI chipset.
Also, I believe his second connection description is not correct. The Signalink must be connected directly to a USB connection on the computer. There is a special cable required for each type of radio that connects the audio outputs of the Signalink to the radio. The radio serial port must also be connected (through the USB - Serial adapter) to the computer directly. I hope this helps. 73, Bud N7CW On Fri, Aug 14, 2015 at 2:41 AM, Radivoj Kar, F6GNZ via DX4WIN < [email protected]> wrote: > There have been no responses for my requests.
