Not only when the exact same thing happens, but anytime something
strange happens, the first thing to check is the cables (including the
coax). It happens so often.
At the workbench, my 3 foot BNC to BNC cables get quite a workout from
so many plugging/unplugging cycles - there are 3 or more cycles for
every transceiver that I service, so the connectors get a lot of use.
At the first sign of something strange, I substitute a different cable
(I have learned my lessons long ago). That does remind me - in the next
few days, I need to make up some more 3 foot cables, I am down to 3
known good ones.
Always suspect the easy stuff first - it may be counter-intuitive, but
it is the cause of problems more often than not.
Telling on myself, I recently tried to check a KIO2 for communications
with the computer, so I cranked up Ham Radio Deluxe to see if it would
connect. It did not, so I spent some time trying to 'scope the
communications path in the KIO2 - about half way through my tests, I
glanced over at the computer and found the serial cable end on the
desk. Yes, I had tested something else with that computer serial port
and forgot to re-connect the normal test cable to the computer. I guess
I am old enough to blame it on age, but just the same, that is only an
excuse! :-)

I did realize I had just plugged the KPA500 cable into the Y cable
and FORGOT to tighten the screws. My error for sure. Tnx agn guys. If
this happens again I'll go to the cables right away.
