[Elecraft] Boost power supplies for RF amps

[Bill Frantz]

I'm trying to reconcile this advice with our experience running 
QRP field day. We frequently have two or 3 K3s on a single band 
(CW, SSB, Digital/GOTA). We use batteries and solar cells since 
our site does not permit generators. When the radios are being 
fed from a charged battery or a battery being charged from the 
solar cells, we don't have a significant problem with 
interference between stations. (Antenna placement helps a lot 
too.) When the voltage drops, the complaints increase.

Of course, our 5 watts is quite a bit below the full power of 
the low power RF amp in the K3.
