3 cm amplifier

Hello,

I have a question concerning the switching of a 3 cm pa.
What is the best thing to do,leaving the PA running or just switch it
on when pressing PTT (with a sequencer ofcource).
The PA doesn't have a sepperate bias pin so i have to switch the main
12V.
This gives a big difference in the size of the heatsink/cooling.
Some OM i spoke to are in faver of leaving the amp running for
stability purposes.

regards
Bart
