[Amps] 87a cured

[Charles Harpole]

For over 5 years, my Alpha has sat in the shack with high humidity and temps of 30-34C.  During that time, it automatically went to Fault 9... and sometimes Fault 20.... when tried to use.  The "go to fault" was all over the map in terms of when it would occur but it was usually early after turn on.  The air conditioner would be switched on in the shack only during operations.
 
My very smart friend worked on it several times, including replacing all those expensive PIN diodes, but the problem reappeared soon after that.
 
On advice of several locals, I began recently to run my shack air conditioner continuously at about 25C. and set to "Dry."  After abt 40 hours, I tried the 87a.  Perfect operation resulted with no other changes.  It now drives, outputs RF, and in all ways works as it should.
 
I guess it just likes cool and dry.   Or the local spirits do.  73,
