[Icom] Battery Operation

[William Lambing]

The problem with battery operation is:

What is the output voltage?

Is it 12V or 13.6/13.8V?

Many radios sound absolutely horrible at 12V.  Some shut down, some =
start to FM...and on and on.  Listen to Midcars or ECARS someday while =
some of these guys, mobile, with the engine shut off attempt to contact =
someone.  95% of the time, they are completely unreadable.  Now if you =
run CW...then all bets are off..!  This mode usually works just great.  =
It is the SSB peak output that gets you in trouble.  Sometimes you can =
cut the power down to 50W and things are ok.....for a while until the =
12V gets lower and lower..!

Using a charger whilst operating on batteries, introduces hum from the =
charger.
