Ralph,
Motorola did make a special power supply for running the Micor station off of a
12 volt battery system. It is Model TPN1121A.
They are fairly rare but very nice. I use these on our solar sites here in
Western Oregon for our Micor repeaters.
I would be surprised if you could not come up w
Does anyone know what the replacement button kit part number is for an A9
Spectra? My A9 control head has most of the labeling rubbed/worm off all
the buttons, and Motorola has 5 "possible" on their parts website - they
only describe them as "button kit" so I have no idea what I'm actually
looking
I don't think I ever tuned a hi band LLT. I know the alignment procedure for
the low band LLT tells you to drop the power supply voltage to something like
11 volts (when tuning the transmitter) and then back to normal power supply
voltage for final transmitter alignment.

Mike,
The 150 Mc. has exactly the same 50 Mc. "driver" which, instead of going to an
output filter, goes to the varactor tripler. So the VHF hi radio has the worst
of both worlds; the germanium "drivers" AND the varactor. That's precisely why

Hey group
Does anyone know the points to put a discriminator tap on a TMX8810/8825?
Hi Curt,
Yes, that is the way I recall seeing the Dual Band antenna in the old DB
products catalog. Have you tried checking the upper and lower halves to see
what kind of SWR you have at the operating freq. ?? If it is convient, measure
the end to end length of the upper and lower dipoles. T

I am building up a Micor repeater using a unified chassis
for use in Montana on a Mountain site. Site owner does not
want a micor power supply. He has station batteries and charger
system.
Does anyone have a regulator circuit to make the 9.6 vdc and audio 12 vdc
necessary for the unified chas
Good day Doug. I have a DB dual band antenna similar to what you are
describing, it has 4 folded dipoles for two meters, and 8 folded dipoles
for 440. These are two on each side of the pipe for two meters and four
on each side of the pipe for 440. The diameter of the pipe is slightly
smaller

Hi Tony,
to answer your question if it will work, the answer is yes it will and i am
doing it on a site the same way. You will however need two dual isolators to
add to each transmitter. You will tune the reject the same way as you would
normally for the specific frequencies.
Good Luck,
Mike

Yep I have 3 rotors and have box's for all of them .. I think I have a
couple spare kicking round if not I think I know where there is some I sent
a messgae and waitting for an answer from him ..
if you can wait till the 24th I will be going to a big hamfest and shall
look for you there

Yes. Assuming the duplexer provides sufficient isolati
Steve;
Your CD-45 controller is for an 8 wire rotator. I need a 4 wire controller
for a AR-22. An AR-10 or AR22XL will also work for me. Thanks for your
reply.

Hey everyone,
Thought about this yesterday...would it be possible to use a
conventional pass/reject duplexer to combine two UHF transmitters into a
single antenna?
Example:
Transmitter A is 453Mhz
Transmitter B is 443Mhz
Low-side pass 443, reject 453 (10Mhz spread); high-pass 453, reject 4
Paul and Chuck,
Thanks guy's, that's what I was looking for. 73

I had to build one of these 5 years ago. I had a mast from a DB-413 that was a
406-420 cut antenna. I used a New DB-408 and a New DB-222 and mounted the
DB-408 on top and the DB222 on the lower part of the mast.
I used a good quality RG-8U coax jumper to the bottom of the mast for the
DB-408.
While you have the high band version, the low band version
has matched quad germanium finals that are / were very fragile.
When the California Highway Patrol surplused the 51LLT Motran
fleet (they went to special production 71RTA Micors) I sent
a Motran in a custom fitted wooden box, and both a ca
