If you believe you know of more "appropiare" groups, or just wish to
drop all pretence and continue developing this into an argument, please
enlighten us all, cheers.

You seem to be the one pushing for an argument, I just can't see why you
would bother posting in CB and Scanner groups,

Mate, these groups are inhabited by radio enthusiasts whose interests
don't necessarily begin or end with Amateur radio, CB radio or scanning.

Had I posted with robot-like compliance, I wouldn't have posted the
question at all, since there is no news group for Motorola commercial
equipment. I could use your same logic to not even post it to any of the
amateur radio groups as well.

I think you really do understand why it posted to these groups, it's just
common sense. I wondered before originally posting whether I'd hear from
some pedants, sure enough I did. Oh well, par for the course isn't it...
Some people don't necessarily read whatever groups you feel
are more appropriate, hence cross-posting to a range of radio related
groups.

All I was asking for were the specifications of a piece of radio
equipment, nothing more. But some will never miss an opportunity, no
matter how petty, to have a go at someone over the flimsiest of pretexts.

have look here, http://www.eserviceinfo.com/ there is a lot of Motorola
stuff there,

Thanks for the link Warren, will check it out.

The general consensus is that it did indeed come from an MSF5000, I
started a thread over at batlabs just prior to posting to these
groups, which has paid off somewhat
(see: http://batboard.batlabs.com/viewtopi...&unwatch=topic
) but now of course there is also some conflicting info in the
replies... info on Motorola gear can be hard to find!

I'll play it safe and keep it below 3W until I get definite
confirmation of the specs being different. Cheers


Good idea. I worked on Motorola, etc, for the past 35 years, up to
and including MSF5000 UHF like you have. Best I can recollect, never had
an PA that took more than 1 or 2 watts drive..... I could be wrong,
maybe.... its been a couple years.

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,

Jas Commerical Printers

West,,Mumbai-400064.Maharashtra.
Send : On-Line Trade Inquiry

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

You are correct , I have made the conversion on several 828 PA with a
resistive network , latest is an 828 lowband vhf on 6 ,eters with 1 watt
in give 24 watts out , actual drive is about .55 watts via the resisters .

Hello atec77, thanks for the verification, much appreciated, I really should
have thought to ask the fellow I bought it from at the Gold Coast Hamfest,
but it didn't occur to me at the time, I really went down to buy some
N-Connectors as they have had them before, mixed types secondhand in a
plastic bag for around $15 , wouldn't you know it, there wasn't any there
haha, ah well, ya get that :-) ,

N/p
crimps are very cheap . and the pliers are now affordable

Had I posted with robot-like compliance, I wouldn't have posted the
question at all, since there is no news group for Motorola commercial
equipment. I could use your same logic to not even post it to any of
the amateur radio groups as well.



Actually, now that I think about it, your question would best be posted
on the moderated Yahoo group for professionals in the Land Mobile Radio
industry..... LMR. http://finance.groups.yahoo.com/group/LMR/

You WILL get a decent and accurate answer to your question there.

G'day,

Looking for specs on this amplifier:

http://img100.imageshack.us/my.php?image=pa2modhi7.jpg
http://img484.imageshack.us/my.php?image=pa1modzp8.jpg

Don't know much at this stage, apart from 4Watts drive (@
430-480MHz)=
approx. 150W output, draws well over 30A from my poor struggling
power
supply. I'm not game to up the drive any further until I know the
specs!

Basically any specs or any info at all would be great, thanks in
advance.

Cheers,
Let's take a wild guess here, you want to use it on the UHf Chook
Band
to
talk into the 5 w output repeaters, if that's the case, and I do
hope
I'm
wrong, you'd be better off with a decent antenna system,
WRONG, I plan to cause havoc on the remaining analog police
repeaters-
ya idiot. There's more to the UHF band than CB radio you know.


You better be CAREFUL as I will dob you into Simone Templar.

I bet that has him wetting himself and quaking in his uggies.

LOL, quite.

Amazing isn't it - cannot discuss power amplifiers in these
Aussie groups without the usual knee-jerk assumptions, irrespective of
being perfectly within the law to own and use in an appropriate manner.
Apparently no Hams here use amplifiers I guess.

May have something to do with the fact that you posted into a CB
newsgroup????????????

You might want to learn more about interpreting Usenet headers before
trying and failing to flame in a successful manner. Good luck with
that.

Hmm...

You see, I bet, and this is just a guess mind you, that the part of the
headers that solicited a comment was:

"Newsgroups:
aus.radio.amateur.misc,aus.radio.cb,aus.radio.scan ner,rec.radio.amateur.equipment"

And in particular:

"aus.radio.cb"

Seeing as most people posting in this group about high powered UHF gear are
actually referring to high powered UHF CB equipment.....

The fact that you posted no indication that you were seeking info for
Amateur operation but did refer to the frequency range being up to 480MHz,
again within the scope of UHF CB, probably only strengthened that fear...

But that's just my opinion, after all I'm still learning to read Usenet
headers...........................................

Not a problem, I hate usenet as no one shows any respect for each other.
take a look at the **** that goes in within this newsgroup

I generally use usenet or a forum when I want to find an answer, not post a
question and get a ****load of smart ass responses

I know i'm going to get flammed for saying this but I don't give a ****

Welcome to aus.radio.scanner, please feel free to ask any other questions
that are not related to the topic of the newsgroup.

It's a radio related group. Some who subscribe to ARS do not subscribe to
other related groups and vic-versa.

I'd suggest joining www.batlabs.com and ask on there if you want to know
technical specs, whilst there are some people in this newsgroup who
actually know what they are talking about in relation to the technical
side of Radios. I am not one and there are a large portion of people who
response with smart ass remarks

Well, that is Usenet - uncensored and therefore you get the full spectrum
of human behaviour. I have no problem with that to be honest, MUCH more
preferable than censorship or 'moderation'.

Thanks for your suggestion batlabs, I did post a question there on
this matter prior to posting to these groups. I have received a few good
replies, but still seeking those elusive specifications.



Cheers
