[Elecraft] KIO3B

[Mike Harris]

An observation.

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

I use Logger32 and prior to installing the KIO3B my 3GHz clock PC 
comfortably delivered software CW from within Logger over RS232 without 
the need for a Winkey unit.

I have been running the CAT/audio over USB but apart from checking that 
CW keying was working, lights flashing, never listened to it. This 
weekend, however, I did a bit of S&P in a CW contest using Logger macros 
for calling and serial numbering. The CW was rather choppy and 
noticeably staggered at times. So much so that it put me right off my 
stride and I had to resort to hand keying.

For experiment I transferred CAT and CW over to the K3 RS232 port driven 
from a real RS232 on the PC and everything was back to normal. Toggling 
between USB and RS232 equally toggled the "problem" on and off.

Expanding upon this I transferred K3 RS232 to a USB/serial converter, 
original Elecraft with Prolific chip set, and all was still OK. Couldn't 
hear any difference between the native RS232 port and the USB adapter.

My non-PC specialist conclusion is that either the driver supporting the 
KIO3B or all the USB routing action within the KIO3B is causing the damage.

No big deal for me to transfer CAT/CW during my very infrequent CW 
contest activity, just unfortunate that in my cast the one cable 
solution at present isn't.

Any thoughts.
