[Elecraft] Re： XV50 cooling

[Johnny Siu]

Hello Gentleman,

The structure and architectural of XV50 and XV144 are the same.  The proposed test from Don would be useful.  Eventually, we do need an official confirmation from Elecraft some time in due course.  Let us stay tune and wait for Don's test.

cheers,

Johnny VR2XMC

I would think the major concern would be elevated noise or 
change in the first stage's semiconductor device parameters 
from the receiver's input device temperature increase, not 
from tuned circuit drift or PA noise.

I can't imagine a tuned circuit wide enough to pass six 
meters drifting so far as to change sensitivity, or really 
any meaningful change on a band like six meters.
