[Elecraft] loss of RX sensitivity

[Dave B]

Wunder, I'll second you on that!

Of all the 1000's of RF connectors I've assembled and used over the
years for my own hobby and at work.  The venerable "UHF" series have
always proved to be the nastiest most unreliable types ever.  Period.

All my own personal radio kit, either get's them replaced (Sadly, not
always an easy job) with a N or BNC (in one case, a TNC.)  Or a BNC (or
N) adapter is securely fitted as a permanent fixture (including LocTite
on the threads, in mobile/portable situations!)

I also use BNC's at HF, as we do at work.   They can happily carry well
over 150W at up to 220MHz even in the presence of some very bad VSWR's
(6:1 or higher.)  Assemble them correctly and look after them
physically, and they will last a lifetime.

The UHF series are just plain unreliable.  It is no surprise that the
military (NATO) don't use them any more.

73.
