[Elecraft] USB to Serial Ports adapter: a product test

[Don Wilhelm]

Ken,

I believe the radio will not take direct RS-232 input, but it needs TTL 
levels derived from the RS-232 signals.  I ordered a serial port 
programming cable from Powerwerks and when it arrives, I can tell you 
the relationship.  In the meantime, I cut the USB end off the existing 
cable and trashed the USB end.
Be careful what you buy since Prolific and FTDI have both updated their 
drivers to detect the counterfeit chips.

I have only 3 computers all using Windows 8.1 and so far a work around but haven't used it for a month so don't know if it is working today or next time I need it. Please respond here on the reflector as I know other people need this information just as I have for almost 2 years. If possible it would be nice to use the KX3 USB adaptor also.
