[Elecraft] NG0R - K2+K60XV+XV144/222/432 - Setup Issue

[John Hoaglun]

Hi Don, Peter, and the rest of the list.

I think that I might have found the problem.  My IO port appears to the
check out fine.  When I connect the cable I was getting NOTHING on all
of the pins on all of the connectors. I removed the plastic D shell for
the connector at the radio and then rechecked the remote end of the
snake and I then had power on the pins as expected.

It turns out that the plastic D shell is not letting the pins get
inserted/engaged far enough into the connector to make contact. I will
either need to trim down the plastic or replace the D shell.

Once I resolve this little item I can reconnect stuff and retest.
Hopefully that is my only problem in the tune up but anything is
possible as I am just getting started.

It will likely be a day or two before I can get enough bench time to
make the mods and restart the testing.
