[Elecraft] K3 Windows 10 and the KUSB

[Bob McGraw - K4TAX]

Here's a response from a friend that is way more knowledgeable about 
computer stuff than myself.

Pertaining to Windows 10 :

"In the instances of the Rascal I was using for RTTY (Buxcomm) the old 
prolific USB to RS232 converters did not work and they are now in the 
junk box.  I bought two new ones from RT Systems with the FTDI Chipset 
and that solved the connection problems. Dave xxxxx and Bruce  xxxxx 
have had the same issues and either have or in the process of changing 
their old converters out."

I too, with other radios, have experienced issues with the Prolific chip 
sets.  When replaced with the FTDI Chip set converter, all was well.

In other words, all USB to RS-232 converters are not created equal.
