Installed a MSTR II VHF repeater in a six foot cabinet on top of a 17 story
building. The elevator got me to the 14th floor but it took 4 of us to get it
the other 3 flights. It is possible to haul without a hoist. Next time I do
something like this I'm going to remove the repeater and power

Normally I have seen these in Lo-VHF stations but were also made for Hi-VHF.

Whenever we had a lightning strike on the tower you can see the

If I remember correctly the Portable Mobile II used ICOMS for the
channel elements. Just like in the PE series radios.

Be very careful when you put that pass cavity on the transmit side. When I was
in Virginia I had a repeater on 147.06 and late at night I would get

it down to a repeater that a cavity was placed on the transmitter
A few years back I had a problem with the GE power supply similiar to yours.
What I found out the fuse was the problem. Replaced the 30 amp fuse and haven't
had a problem since. Did you try replacing the fuse?

Have you run the repeater into a dummy load and check for desense?

Moto has for trunking a re-group. If the control channel goes down the mobile
are re-grouped to a particular repeater. We have a 5 channel trunking system
with multiple sites so not all repeaters will go down at the same time.

Three areas to look for bad solder connections.
1. Driver on the main PA board (usually Collector)
2. Strap between Driver and PA finals. ( this is on the PA board)
3. Strap from PA board to Filter.

Steve, the reason you don't get anyone on the other repeaters is due to you not
being known to them. Most repeater users will only talk to ones they know and a
different call comes on the repeater they all of a sudden get mic fright and
don't answer :)

Jim, here in Texas your ham plates are yours and when you sell a vehicle you
are supposed to go and get regular tags before selling or trading in the car. I
have seen a number of cars on used car lots with ham plates. Seems that the
owner of the plate and the lot owner does not know the law.
In 1976 I upgraded to Advanced and got WD4AYD. Gee not a novice or Tech.
Dropped that call and requested my secondary call become my primary.

Something I don't understand why everyone trouts TONE access as a cure all for
interference. The interference is still there and for weak signals they cannot
access the repeater because of the interference. Sure the repeater is quiet but
it limits the coverage.
