[TowerTalk] Ameriton RCS4 and N Connectors

There should not be any heat in the first place with 600 watts on SSB or CW.

7/16 are a good connector, but an overkill for MOST amateur installations. 
They are a superior connector to the type N, but, they are heavy, (for 
hanging on a dipole) and expensive.

Again, a PL259 is just fine for HF as long as they are of good quality, and 
installed properly.

In the business, 7/16 is used for low IMD and low passive intermod  at VHF, 
UHF and higher.

It doesn't look like a voltage induced failure, by the looks of it, the 
spring just lost tension, and when it is COLD out, it was fine.  Looks like 
a thermal cycling failure

Like I said, just going to go with N connectors, but no huge rush, as I 
replaced the barrel connector, and all is fine right now.

I've never loved the PL-259, and probably never will.  I'd love to see 
readily available 7-16 DIN, which gives you the best of N connectors and 
PL-259
