Hello Mark,

Yes, I ran into a similar problem a few months ago.   Tried five 
different USB/RS-232 adaptors without success.  Each one 
failed in a different way.   Finally hit pay dirt with a BAFO BF-
810, which happened to be one of the lower cost units I tried.  It 
has worked well now for several months with the following 
limitation.  To get the computer and Pegasus talking to each 
other, I must first start the N4PY software and then turn the 
radio on.  If I have the radio on before starting the software, 
communications is not established.   I can live with that.   :-)   
The same is true for Ten Tec software.

I now have a BAFO 7 port USB hub in line with the BF-810 and 
all is well.

Good luck on your search.
