[Elecraft] problem with K2, KAT100 and K2100PA combo

[jerry]

I had a PowerPole fail on me once.  Dirt or corrosion on the one flat 
contact.
Once was enough.  Back in the day, I had standardized on double banana 
plugs.  In 50 years of ham radio, I NEVER had one fail on me in any way. 
  Only trouble with the double bananas is they're not keyed for polarity. 
  I was always *very* careful about that.

   As a electronic bench tech back in the 70's, I had a lot of experience 
with test sets and connectors enduring thousands of cycles.  The very 
best - most reliable - connectors all had a round pin in a round hole.  
All hail Augat machine sockets!

   The AMASS connectors feature a round pin that plugs into a round hole. 
  It has just the right spring tension.  They are polarized - you can't 
plug them in backwards.  They are popular with the RC drone crowd, but 
are also making it into other equipment.

    I am using AMASS XT90 connectors on my kilowatt LDMOS linear project.
