Re: [Elecraft] Attempt #3 - Any larger more efficient heat sinks for the K2/100 Lid PA?
I've never had any such heat issues with my K2/100, Paul. I wonder if there's some other issue you need to address? Are you operating in a mode with a very high duty cycle (RTTY, PSK31) at more than 30 Watts or so? That could lead to higher than normal temps. 73, Phil w7ox On 9/27/14, 11:06 AM, Paul Metzger wrote: Sorry, my email GUI by default was sending emails in HTML which does not get processed by the reflector here.

Please, if anyone can provide me with a larger heat sink / solution to cool down this radio, I would be extremely grateful !

Paul, What modes, what power level? Does the internal fan run on high?
