Hi Dave, and to the masses of readers we can hear breathing in the
background...

I've surely done that myself, once with the equipment out and ready to ship
before logic gained the upper hand and I started checking cords and
connectors, finally detecting a male BNC on a cord with a retracted center
pin.  Sound familiar?  :>)

So many of us have had experiences like this. Cord goes bad and to start
off we spend time trying to figure what's the matter with the box, the K3,
the transverter, etc.

One local ham went nearly nuts thinking his box had been supplied with
non-standard type F female chassis connectors until a friend discovered
that the male F connector in question had not been threaded in the
manufacturing process ! That story was source of a lot of local ham laughs.

Carefully checking the cords and connectors *first* seems to be
counter-intuitive. While logic says that connectors and wire in the cords
take all the mechanical abuse, our gut lurch is elsewhere. Maybe it's
because making cords is such a royal pain in the *ss and our subconscious
is rebelling against making another jumper.

I share your pain. Maybe half the time I take advantage of experience and
go after the cords first off. My personal gut lurch is still, "What the
&&$#@$$ is wrong with the <insert box name> now !!!"
