G'day all
well i have a dud CSI-32 pannel and i've tracked the problem down to the
firmwares 2732a going south - rare i know but...
now here is the big ask
does anyone have a copy of the firmware bin file so i can burn a eprom to see
if this cures my woes?
the pannel serial number is R7368
If I want the caps changed, is there anyone in particular at
Crescend I
need to talk to? I wasn't aware that they would support the
Milcom line.
No, just fill out the RMA form from their web site. You might want to ask
for an estimate or quote before you send the unit in, but they'll want
Thanks again!!

You might talk to Mike Burchfield AA9CQ (Not sure of his call)

Greetings Repeater Gurus! Hope everyone had a great weekend!
I have a few questions for youhope its an easy answer.

Hello to group,
Is putting a MOV from hot to ground, neutral to ground, on the primary of the
transformer of the power supply a good idea..
I have a ICE surge suppressor on in front as well but thought I would put more
inside the supply for back up.
Also, are the MOVs that radio shack sell any
Don't use Radio Shack. You're just asking for trouble. Buy from a quality
supplier. Others on the list can give you preferred vendors.

I presume you mean audio-squelch board.
Does he need a single PL tone encoder card for the card cage?

I agree fully with NOT using Radio Shack low quality run-off manufacturer
seconds. Use NTE 140V. The trick is you need to use THREE. One across the hot
and neutral. one from hot to ground and one from neutral to ground. MOV's are a
funny dog they do not usually short but degrade very quickly
Two things leap out at me: Your generator has some very serious regulation
problems, and may be undersized, and your Astron power supply must not have
the correct fuse installed. If the MOV fires, the fuse is sized to blow
instantly. That said, Astron has been known to install MOVs that have a

look at them.

I replaced two in two ASRON power supplies that got zapped with 220 and seem
to be still working. I would recommend getting a good brand if you have the

Regarding your last question, an MOV normally will go into avalanche mode
when the applied voltage exceeds its threshold value. It becomes a low
shunt resistance, which should blow the input fuse in the device it is
protecting. Once the voltage is removed and the MOV cools off, it usually

I'm not that big of a fan of MOV's, but
There is no reason to have to put them period.
Extra protection is well.. to each his own. MOV's are not the greatest, but
certainly wont hurt

Hey guys,
Alright, i've just been giving the responsibility of being the head contact
for a commercial repeater, and pretty much in charge of it.
It's a damn good machine, a quantar. The one thing i'm not the best at is
voting receivers. They only have 2 of them. Here are a few questions, how
