[Elecraft] USB to RS232/DB9 adapter

[J F]

Hi Chuck,

I had similiar experiences with several USB adapters.
It seems to be an issue, not just with the K2, but
other devices as well. 

Drivers may help, configuration is important as well.
On my laptop, the default com port was com11. Your
equipment might be looking for a device on a different
com address (ie N1MM looks for com1, but you can set
it for a different port).

Don's point is important to remember, you still have
to use the K2 DB9 cable to interface to the USB
adapter.

I also found many of the multiport USB devices were
useless (or more of a pain to use than they were
worth).

This is what I found that worked (except I can't use
it to send CW via N1MM) with the K2 and my computer:
Tripp Lite U209-000-R Serial Adapter - mini USB Type A
- DB-9 - male . Your mileage may vary ;o)
