I am using a K3s but the KIO3B is the same for us and I believe the
config settings are the same for a K3 with it. I have the USB from
the KIO3B going to a powered USB hub with 5 devices total on it. I
have the RS232 from the K3s going to a P3 with the CBLP3Y.
I was working the Stew Perry contest last night, using N1MM and using
its macros to send CW. The only problem I had in sending is in
remembering which function key to hit as using a keyboard to send CW
is new to me (Well... I did have an Apple II+ back in 1981 that had a
board in it for CW/RTTY but nothing keyboard to send CW since then)
Someone (here, I believe) kindly helped me with the settings to use
with N1MM & the K3 and be sure if you use N1MM, to have in CONFIG,
the PTT-KEY set to OFF - RTS. I don't know if any of this will help
you but I can say that up to 30 WPM, there is no problem on this end
whatsoever. Your solution will likely be easy to resolve once you pin

> Installed a KIO3B in K3 #345, no problems all working either RS232 or
> USB or both together for CAT and audio.

> Expanding upon this I transferred K3 RS232 to a USB/serial converter,

> My non-PC specialist conclusion is that either the driver supporting the

> No big deal for me to transfer CAT/CW during my very infrequent CW
