I need a preamp for a VHF Mastr I Exec. Anyone have one?

I think it's a standard Molex or Amp connector. You might be able to buy it
from Mouser or Digikey. I can get the Motorola part numbers for the cable end
but you will pay less elsewhere (unless it's a custom part).
I can get you the wiring for it, but I'd guess the center pin is ground and the
George have you received a reply to your query re manuals ??/Let me know-I
may be able to assist??

I'm working on collocating a 2-meter remote base with our repeater, and
naturally every time the repeater transmits, it makes the remote-base radio
totally deaf. I've been playing with quarter-wave stubs with some success
(and have lots more ideas/experimenting in mind) but would like to hear

Maybe you could use a fixed 9 volt three terminal regulator and lift the

I once read that there is a problem in lifting ground on those 3 terminal
fixed regulators in that you lose output short circuit
No pigtails..thanks for all the suggestions.will try another one...

Geez, Mike, you're not asking for much, are you? I assume you are using a
half-duplex radio for the link, and it receives on 145.110 MHz and transmits
to the distant repeater on 144.510 MHz. So, you need a high-Q notch at
146.850 MHz to protect the link receiver at 145.110 MHz, while not
Thanks I will check that out and get back to you.
Thanks

Eric,
Yeah. we're always trying to do something for nothing! We're a low-budget
operation and I'm pretty much left to my own devices to try things that the
club wants to do. The good thing is, if this one just doesn't come to
fruition, we haven't spend any money on it.
The radio is an
Thanks to everyone for the info suggestions. Lee's route is the one I was
planning to take, using the schematic from the National Semiconductor
datasheet for the LM317. Just wanted to make sure I wasn't exceeding the
regulator's ratings (was going to hang TIP3055 pass transistor on it if I

exciter i have one and i need to put it in service on the 444 mhz band

Will,
The tuneup instructions for the UHF PLL exciter are in LBI-31209, here:

I erred in stating the tuning instructions are in LBI-31209; you need to
have that manual, but LBI-30200 is also needed:

The GE Mastr II UHF exciters that I have are not PLL. They do use the direct
FM Icom that is used on the VHF PLL exciter, but the UHF model just multiplies
the crystal frequency like the phase modulated exciter. It is a very
straightforward tune up, peak and dip like the phase modulated
Well Mike, here we're linking to a 145.49 repeater using an Exec II
for the linking radio. The antenna is a single dipole (from an old
DB264) about 80 ft. below the DB224 repeater antenna which is on
147.06. The 5.49 repeater is 25 miles away. We have no desense
whatsoever and we use no
I am using an in-band link on 2 meters to another repeater 10 miles away. I
use a GE Mastr II mobile radio with the amp removed and feeding the exciter to
the low pass filter and antenna relay removed from a defunct amp.
I am using a 3 element beam pointed at the other repeater only 20 ft
Can anyone please offer me some assistance.
I am trying to link my VHF repeater to a club machine on 440 MHZ.
For now I received permission to link directly on their input until
the club installs a remote base and yagi next spring.
There repeater is about 20 air miles away. I am using a 5
You can try lowering the antenna.
You can try a better antenna, one with a better front to back ratio
and better side lobe rejection.
If that does not work, you can try something that we do to our
microwave dishes when we receive off axis interference, place a
shield near the side of the yagi
