Arvo -- there is no desired adjustment of the gain due to the extra voltage.? That is the goal of the few extra volts...to get a few extra watts.? You most defiantly do not want to adjust anything...just let the extra volts do their magic thing to the finals and bask in the glow of accomplishment.?
Having said that, I did adjust the PA bias per instructions when I first got the rig and used a 12v wall wart for the the whole radio.? Did I need to do that? Na...it was set fine from the factory, I just wanted to hook up my meter and see what every body was talking about. I've never set the bias of anything in my life, never mind two little plastic/metal thingies in the back of the board.? So I used the meter and twisted the little driver pot till I got the 100ma. I even did it a few times just to show off to myself. hahahah. I'm easily impressed. hahaha.
Anyway, there MAY be a case for adjusting the PA basis when you (me) use a higher voltage, I have no idea and didn't look it up.? But I'm not going to mess with it regardless. Having flown high to the sun with my first successful PA bias adjustment, I have zero motivation to try my luck again. hahaha. [but typically I will mess with something until I break it, then I figure that I now understand what is going on...well sort of..hahah]
Now, I did bolt on larger heat sinks (hack sawed from a ancient Pentium CPU heat sink), and I'm glad I did -- given that I left the TX on full power for 15 minutes while in stupid mode (a new digital mode for the inattentive and easily distracted).? Things got all Chernobyl on me, but everything recovered.
So the heat sinks and fuse were the only adjustment I made to accommodate the higher voltage.?
