[Elecraft] K3 No Receive, No Transmit - SOLVED

[Charlie T, K3ICH]

What were those dinky looking cable to board
connectors that Drake used in their TR-7?  I'm
certainly NOT advocating a change to those, but I
don't think I've ever seen them used on any other
equipment.  As chintzy as they looked, I seldom
ran into a situation where their connection was
flaky. They used the center conductor of the coax
and had some sort of crimped on shell for the
shield.  They were also a bit tricky to align, but
seemed to work OK.

Since this is way off the thread, I'd request a
direct reply since I doubt if anyone else cares.

I'd be careful what I asked for.  Sma connectors
are way more difficult to connect than TMP.  In
close quarters almost impossible to turn the nut
on a sma and the fine thread has to be exactly
aligned.  I have two custom-made tools for doing
that and that is not always good enough.

Better would be one of the miniature mw connectors
that just push-on.  But cost comes into the design
consideration.  These TMP are used in many radios
for low-level RF connections that are hardly ever
disconnected (except for maintenance or upgrades).

What you are doing is making upgrades which most
hams never will do with other brands (they get to
buy new rigs instead).  Be glad you are not asked
to solder sm parts to make the upgrade!
