Sent my 1200S to Ken.
He fixed what was broken and let me know what else need to be fixed to bring it back to better than factory.
VERY HAPPY !!

There is a dual access PL 110.9 or P25 - NAC293 on Usery Mt.
448.725Mhz minus offset.
You can see all the coordinated repeaters in Arizona at
http://www.azfreqcoord.org/listings.htm
Also a 927.1625 / 902.1625 at Scottsdale Air Park-cross band to 441.625 tied to North Link.

Does any one have a copy of a schmatic for a Maxtrac D33MJA7JA5AK that they could E-mail or FAX ?
Thanks

1motoman

Will,

You hit it exactly right...

Thanks

I have a D44 KXA7JA5BK - Spectra that I want to change to an A7 head. I have a working A7 head off a 900Mhz Spectra. I have changed the location 6060 to ED from AF with Spectra LAB. Now the problem is after installing the A7 head, the transmitter stays keyed as soon as it is turned on - with no mic ...

1motoman

You might try to replace the cap's in the transmitter audio chain.
They sometimes dry out after 30 + years.

I have a D44KXA7JA5BK Spectra. When I go to change the name of a mode I have a problem. Using Ver R06.00.05 RSS, when I change the name from " mode 1" to something like "449.000" the "." is displayed as" \ " in the display. like 449\000 What am I doing wrong ?

1motoman

Yes it can be done.

All that is required is a little bit banging.

The extra 4 channels are displayed as unique combination of segements.

I got the information from AR902Mhz@yahoogroups.com

If you can't find it there, I can dig through my notes.

1motoman

Get a RJ45-8 (the same as a mic plug)
Connect pin 4 to pin 5.
You know have a diagnostic test plug.

1motoman

If you want a single package, tune up and forget radio with that kind of power - MICOR - old yes put they keep on workig and very cheap.

1motoman

Hartley,

You nailed that one.
Differnt version of Adobe, all the pages are there.

1motoman

Thanks for the informatiom.
Only problem is, the file only contains every other page.

1motoman

I know they are long out of buisness, but

Does any body have a manual for a Communication System Incorporated - Super 32 tone panel ?

1motoman

Its normal for the MICOR repeater. You might check the shields to see if they are RF tight.
If not clean up the finger stock/chassis to decrease the siginal leaking out.

1motoman

OK, I've heard of people putting a mobile dual-band rig, a couple of sealed lead-cell batteries, and control electronics into an ammo can for a temporary cross-band repeater which is weather tight and reasonably robust. And as others have said - if this was an emergency, "get-something-on-the-...

1motoman

The "AK" in the model number is 10 channels - convential
If you find a " BK" it will do 128 channels - convential

1motoman

Try AR902Mhz@yahoogroups.com

1motoman

See if it will fit under the seat.

1motoman

Tried to take one down to the 430mhz-420mhz part of the Ham band -
did not work !!

1motoman

A stock MICOR is rated at .5 uv for 20 db With the factory pre amp, you should get .25 uv. With an after market pre amp I have seen .1 uv or less. Using a pre amp depends alot on the enviroment of the site. If there are a lot of other transmitters, you might not relize any improvement because of the...

1motoman

Yes & no.

There are jumpers in the mic that can change the operation of the buttons.

Look in the manual to configure it to your needs.

1motoman

Are you asking about the factory original channel selector switch?

1motoman

Do you have the HUB inabled ?

1motoman

Will it guyed ?

1motoman

VHF or UHF ?

1motoman

Acording to the book, J40301 (the power connector on the rear) has 5 pins in use.
Pin # 9 = ext DC in (goes to F18002 - 7 1/2A fuse)
Pin # 7 = AC in (goes to one side of xfmr)
Pin # 8 = AC in (goes to F18001 - 1 1/4A slo blo fuse and then to xfmr)
Pin # 10 = Gnd
Pin # 11 = Ext. Battery charger

1motoman

Don't forget to check the ignition sense wire for +12 volts.

1motoman

This might be what you are looking for.

Just think for a minute, why would the FCC want a internet system that radiates thru the airwaves. easy answer, so that it can be monitored from remote distances, that is most likely the only reason that the Govt. is pushing it so hard. Prior to 9/11 it didn't even exist and suddenly in the last 3 ...

It all comes down to money.

If you have the "A7" face plate, you can enable DTMF generation from the front panel with the RSS.

1motoman

What part of the country are you in ?

1motoman

It depends on the band width of the antenna. The antennas are designed to work at any point in the range of frequencies it is made for, the wider the band width, the more frequencies it will work well on. As you get further away from it resonant frequencie, the worst will be the match and as a resul...

1motoman

If you have hear clear on, it has to be on for both radio's.

The problem I have run into is using non Motorola radio's on systems that have hear clear enabled - they sound like Sh*t ! , so alot of the times hear clear is not used.

I have seen mini UHF adapters at Radio Shack.

1motoman

Try a CB shop, or Fry's Electronics.

1motoman

It is a voice compression system.

It is suppose to make the audio more like real speach - with out the frequency - response- roll off you get with the 2.5KC deviation.

1motoman

Are there two bars in the display when you press the scan button ?

If so, what position are they in ? (top, middle bottom)

Have you selected the channels to be scanned from the front panel?

1motoman

The T-band Micor comes in different ranges. 406-420 Mhz, 450-470 Mhz & 470-512 Mhz. Depending on which range you have, determines how much work you have to do to make it work. If you have a low split radio (easly identifed by - it's removable offset transmit oscillator crystal) it should come on...

1motoman

Best bet would be to find someone in your area that has a service monitor to assist you.

Second , find a local radio shop to do the work for you.

With out the proper tools you won't get all the performance the radio could do.

I use 1/4" super flex.

Its like hard line but very flexable.

Conectors are not real expensive and come in all flavors.

1motoman

There are many amature and commercial controllers available that perform the functions you require.

The one I like is

As a radio out lives its intended service life, it gets old.

I would guess the capacators in the audio chain have dried up.

1motoman

If the red dangling wire is connected to the DB-15 connector on the back of the radio.(the same plug that the speaker is hooked to),
it is ignition sense wire.
You need to hook it up to switched + 12 V through a 3 amp fuse.

1motoman

MICOR will go there easly.

Yes I know they are old - but they still work good!!

1motoman

How much loss can you expect at 927 Mhz by using a "N" type barrel to splice two lengths of 7/8" hard line?

1motoman

All that effort for less than 3 db

1motoman

You shouldn't have to change any thing.
I have used the 450-470 PA at 440 with no noticable difference.

1motoman

[quote="mancow"]I think it's one of these he's talking about. It's some sort of PTT type adapter with a clip.

This plug/jack was used by the Air Force in it's CH3 & CH53 helicopter for connection to the intercomm and radio.
