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 res

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

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 all

Apparently I am going to be inheriting the care and feeding of some
MastrII's. First order of business is to get b
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.

Reducing the voltage to 12.8 from the batteries will significantly
lower the output power relative to 13.8v power supplies too..Factory

Hi group whats the deal with the GE Master II PA decks needing to use a
ferrite isolator with a 50 ohm dummy load and a low pass filter between
the PA and the High Q duplexer. Is this something that most do with
the 75 and 100 w Pa's We just replaced one in a Master II Mobile radio
