Hello!!
thanks for reading.. I am looking for a GE master exe II mobile that
its already converted to the UHF ham band and all i need to do is add
crystals tune it and presto on the air..
if you have one laying around and you want to get rid off, please
contact me off the list...

Miguel,
Matthew,
Here's a link

put a small load on the end of the exciter and/or a wattmeter that will read
less than a watt. Helps a little.

Neal,
Good controller, easy to program w/software and very versatile.. I love
mine!

hi im thus anybody here who knows on how to build a very simple
repeater controller with-out any programming just a verry simple
repeater controller...and also how to connect the two radio tnx...
Need the brand and model of the line; there are differences. I probably
have some used Andrew (for HJ7-50) and Cablewave (HCC158) in good
condition; I'll donate one if it will work for you. Email direct.

Motorola has a board called the RICK that does what you want,
So you say your site got hit, so did ours but the crackheads cut down a 12KV
powerpole hoping to get at the building feed cables. Only problem is that
the cable was AU. So our microwave site was down for 2 days and it cost
Edison $22K which would of been $7K had not the transformers split open
I've been looking for the same for a year now I don not think it exists

Hi guys,
Built a link radio out of a MASTR II mobile a while back. 444.575 TX,
447.575 RX.
It is NOT duplexed and the RX section turns off during TX, just a normal
MASTR II mobile setup. The only modification done was to by-pass the PA
and run the exciter output over to the Low-Pass Filter
Most certainly it does ... did that 35+ years ago ... one Motorola
Sensicon 'A' Receiver, one Motorola '80D' transmitter strip, a
power supply out of a Motorola 'Stan Pac' railroad locomotive
2-way radio, a couple of crystals, a pair of gold crystal ovens,

Hi guys,
Built a link radio out of a MASTR II mobile a while back.
444.575 TX,
447.575 RX.
It's the LO multiplier chain that you're hearing. 145.460 * 3 + 11.2 =
447.580 (447.575).
After having the link installed in my basement for a few days, I
realized that it's throwing a
Well, since 145 is about 1/3rd of 447, let's see how
it comes out.
145.46 * 3 = 436.38 MHz.
447.575 - 436.38 = 11.195 MHz
Let me guess; the IF in that receiver is close to, or
exactly that frequency!
I'm sure the radio uses a much lower frequency crystal
and multiplies it up to get to 450 MHz.
I just orderd one of these:

for my portable 900mhz repeater project. I will post a review when it comes in.

Jeff is correct
It's the rx xstal freg x9
16.1602037 x 9 = 145.46 ish

Hi ...
447.575 MHz - 11.2 MHz (Intermediate Frequency) = 436.575 MHz
(output of the receiver multiplier injection chain) divided by 3 =
145.45833 MHz. Try high side injection ... that frequency will come
out to 152.925 ...

I'm pretty sure the IF is 11.2MHz on a GE radio.

Users of MII mobiles as repeaters and/or base stations: You should expect
interference when you cut corners to save a buck and use a mobile for a
repeater. The mobile has no shielding to prevent RF entry or exit, none of the
leads are in/out of the Rx and Tx are bypassed as in the MII stations!

You could add a little RC or coax stub suck out trap tuned to the
offending frequency, placed on the RX input connector.

I'm wondering if you can point me to a link that would further explain lo /

subject, especially in repeater operation.

And ICS has a great little controller for under $25.00 in kit form, total
invested is about 35 or 40 with the rest of the parts.

By the way, I did the same thing except it was with a T-44, you remember
those don't you?
