[TowerTalk] Circuit Board Question

[Steve Hunt]

Agreed!

However another factor in the design process is the duty-cycle of the 
mode. Voltage breakdown is likely to be pretty much instantaneous and 
mode independent; but excessive thermal dissipation will be associated 
with a time constant, and depend on the mode.

Then again perhaps you folks are all running 1.5kW 100% duty-cycle RTTY ;)
