[600MRG] No Corona Dope Needed.

[Paul Signorelli]

Sherlock thought the same thing about high altitude operations but found out
that Pikes Peak can cause some RF and HV failures.
See https://www.airborn.com/docs/OpenAccessProvider/product-documentation/ptb35.pdf?sfvrsn=12
Also Multipactor Discharges are described at

I found another spot where my 866's had arced from the tube socket to the mounting hardware. Corona Dope won't fix this, I have ordered some new 'all ceramic' tube sockets.
This may have been caused by my high altitude operations in Colorado.
It could have been a Multipactor Discharge !
Didn't you read Sherlock's paper on "The Failed State of Electronics"?
Get CQ Magazine, Dec. 2016, p.34-37.
