Re: Heat sink

 

No? mods but have adjusted PA? for more output..
It started as an experiment to see what? I could get out of the Final.
I started with lower values and went up over time ..
I had purchased a half dozen finals from digikey --- just in case... but never used one yet

I have all 3 of my bitx running from 9-11 watts.
I have large heat sinks and fan on each . using digital modes - jt65 and ft8 - they stay very very cool.

They have been running? at the above levels for hours of continual working the digital modes and no issues...

Measurements with 2 power meter - and swr 1.0
Also same level recorded into to a dummy load.

6w sounds about right.
11w sounds really high for 13.5v, I'm curious how that was measured.
