Hello Jasco , I'm going to do something I don't do very often and that is
apologise for jumping to conclusions, I must admit when I read your
original posting I thought, here we go again, some UHf CBer wanting info
on a very high powered Amp, so he can stomp on every one else, for that I
do apologise, in my role as an emergency monitor I get quite a few of the
power heads deliberately interfering with the emergency repeaters which I
monitor daily, I have even had dead set deliberate interference during
actual emergency calls and whilst in contact with the Police Comms Centre,
as in, microphone in one hand and the phone in the other, the Police
couldn't believe what they heard, so I tend to get a bit touchy when it
comes to very high power on UHf CB.
now back to the Amp, I see on the circuit board there is JAS marked in
several places, I'm wondering if this is the manufactures identification,
if so you might get some info from this mob,

I ran a search on the net and came up with that mob, with a bit of luck
they may be the manufactures and should have the info you require, wether
the buggers will give the info is another thing , once again sorry for
****ing you off,
Cheers,
Warren
Jasco,
Maybe here, more info on MSF5000 if you already haven't got this
link ,
http://www.repeater-builder.com/moto.../msf-tour.html .
The following info has nothing to do with Motorola , but I recently
purchased a Philips 828 back end (25 Watt PA from 828 radio) which has been
modded so as to run a hand held 2 Mtr , there was no info available with it
regarding input power, and me being a silly bugger didn't think to ask the
bloke I bought it from :-) ( Hamfest ), so at first I set the h/h to 5 W
max, the amp output was 25W, then I set the radio to low power, 0.5 W , the
output was then 20 W, so I came to the conclusion to run it at low power 0.5
W, as that would most probably be the safe input power, 5 W input only
raised the output by around 5 W not worth potentially blowing the driver or
something major, unless of course the driver had been changed to a more
robust type ?, in your case, maybe try at 1W then say 3W and see what the
output difference is , if it's only 5 or 10 W on higher input power of 3 W
its probably safe to run it at 1 W input,
Cheers,
Warren
