[Elecraft] T/R switching problem

[Robert Redmon]

I have encountered this phenomenon on a number of occasions over the 
past 50 years. In my case, every time, the problem was an oxidized 
connection or relay contact. Transmitting a single dit would clear the 
problem (temporarily), but the condition would always reappear after a 
time, sometimes after only a few minutes, if no other action was taken. 
In most cases, lightly burnishing the connection or relay contact (by 
far the most common culprit...in my experience) would resolve the issue.

73, Bob
