[Elecraft] question about Elecraft receivers

[PTA_ABD]

< I have not heard of many incidents with diode damage with the K3, but 
with the K2, we hear of this problem frequently.  I do not know why the 
K3 has escaped damage to the wattmeter diodes, since its power control 
mechanism is similar to the K2.>  from  W3FPR

Not quite. My early K3 developed the bad wattmeter diodes, even though not exposed to any obvious static buildup. I know of another local unit that had the same problem. They were replaced with a more robust set at Aptos, and working fine ever since. I'm sure more modern units have the better diodes.

I "castrate" all my stuff before threatening weather arrives: everything is disconnected, including AC. Any radio stuff has no cables attached. Outside cables have Polyphaser or static discharge devices, but I feel better doing what I do.
