[Elecraft] TMP connectors (Jim Rhodes)

I use Dow Corning 5 Compound dielectric grease on all of my outside coax 
connectors, just a little pinky size on the SO239 or F connector. 
However I use it to prevent any moisture contamination but I suppose it 
could inhibit any dissimilar metal corrosion or oxidation. Not sure if 
there would be any benefit for your application though plus it's just a 
tad messy. Since you have an intermittent problem I suppose you could 
try it and see what happens (or doesn't happen.)
