I do not largely recommend the Astron BB series for proper battery
maintenance. The issue is the charge voltage is directly related to
the operating voltage so to se the appropriate float voltage you need
to tweak the operating voltage pot to a lower level and the charge
current is strictly

Mid power Mastr II stations used 15 amp factory power supplies...100w
stations used 30 amp power supples..
so.. probably less than 15 amps.. maybe 10-12..
Reducing the voltage to 12.8 from the batteries will significantly
lower the output power relative to 13.8v power supplies too..Factory
Let me clarify - this is a Mid Power Mastr II station, however, it has a
high power P/S (original 15 amp power supply was repurposed).
This factory supply at no load typically sits around 15 VDC with 121 VAC
input.

Apparently I am going to be inheriting the care and feeding of some
MastrII's. First order of business is to get
The loaded voltage is about 12.5 to 12.8 comparable to what would be
in the trunk of a car starting at 13.8 at the battery alternator
connection.. including voltage drop...
That was the design anyhow... Astron's or eq are some what of a
problem as they really do not sag at all.. 13.8 all day

Careful..
1) You should never let a lead-acid battery go completely down, not even a
so-called deep-cycle one, if you want it to last a long time. Look at the
manufacturer's specs and build a voltage-based cut-off switch that will shut
down the output before they go below the manufacturer's

With regard to the Intermittent Duty 50 watt Stations, what is the lowest
these will tune down to without excessive spurs?
I have a Mastr2 VHF station we're looking at placing in our command trailer
for temporary operations - AC power most of the time, but would like to have
it draw as little
, you can use only the driver if you need low power out.

An isolator with appropriate harmonic filtering AFTER it (they create
harmonics, which are not friendly to your neighbors), presents a nice solid
non-reactive 50 ohm load to the transmitter. It doesn't matter if it's a GE
MASTR II PA, or someone elses. Many Motorola PA's have the isolator built
