[CQ-Contest] Question about USB to Serial (DB9) port adapters

[Rick Lindquist, WW3DE]

I've used Prolific and Belden serial to USB adapters without problems for
RTTY and rig control. Don Hill, AA5AU, has information about this on his
RTTY page, http://www.aa5au.com/gettingstarted/rtty_start8.htm

The general consensus seems to be that the FTDI chipset is most
compatible and most reliable. You can find products that use the FTDI
chipset at:

I'm not affiliated with FTDI nor ByteRunner - just what I've heard "on
the block"...

I went through this a while back and my experience was that many of the USB 
to Serial Converters did 
not work in all applications.
 
I did try an I/O Gear one and, although it worked OK for rig control, it 
did NOT work for RTTY FSK keying.  This is where I believe the FTDI 
requirement comes in.  I ended up getting the Keyspan unit and it worked
fine.
 
I don't think you can go wrong with either the Keyspan or Byterunner 
solutions.  I can't vouch for any of the others.
