Wade,
I've found that the power output can be dependent on the operating
frequency. For example, my vhf-hi Maratrac mobile runs at 100w above
146 MHz, but on repeater inputs in the 145.xxx range, the power jumps to
120w. Fortunately, I don't need the lower frequencies that much so the
radio
Hi Wade,
You're correct. Ground the PTT pin to TX. Mic audio would go to the TX
audio output on the controller, or else this is gonna be a rally
quiet repeater. ;)

The short answer, Grady, is no. The Maratrac uses the same oscillator
for transmit and receive. To make a one-box repeater like with a Micor
or MastrII, you have to be able to separate the TX and RX so that both
work at the same time. Just can't be done with a Maratrac.
That being said, the
As usual, Batlabs is your friend...

They give functions for all but 2 pins, as well as part numbers for
connector kits. I have the RSS for the pro series (older version, but
should be ok). If I can determine what pins 19 and 20 do, I'll pass
that along.
If I remember rightly, Nate, the keying is via 2 ridges on either side
of the locking tab. They allow the connector to only be inserted in the
centered position. If you don't need to flash, the 16-pin kit is the
deal, and probably cheaper. :)

The 16-pin connectors work just fine on CDM mobiles. They install on
the middle 16 pins, leaving one pair of unonnected pins on each side.
I worked for a Moto shop a few years back and we used them frequently.

Hi Peter,
The tone panel's function is to let each group hear their own users, but
it doesn't prevent someone from stepping on someone else when the
repeater squelch is already open (as it is when a valid user is
talking). Most radios have an activity light that will indicate if the

Hi Henry,
The 8 channel GM300 units have a different logic board from the 16 channel
units. On an 8-ch radio, pin 8 is CSQ/PL Detect and is active low, no
programming option at all.

If you use the info on Batlabs, the hex edit for the UHF unit is only
changing 2 bytes. Don't get much easier than that. Dig in there ;)

Best thing to try :
Get the MoSlo program here... http://www.hpaa.com/moslo/
Use it at the default speed (IBM PC/AT 4Mhz). This should allow the
R100.com program to run on most any system. If it still won't run,
DISABLE CACHE in your CMOS setup and try again.

I agree with you that the MTR's are super machines... but I was

machines wouldn't do 2 meters... something about the VCO's or some such

Far as I know, TLD would be hi-band VHF. A UHF board would be TLE.

Hi Brian,
In my years as a tech at a Mot MSS, we were told that most Motorola
PA's perform to spec until about 50% rated power. For a 25W radio, I
have run them at 10W with no problems. At 10W, with a good fan, I'd
say a Maxtrac/Radius mobile would probably be ok for continuous duty.

Hi Jason,
Sounds like you have either a Maratrac or a Radius M400. The Maxtrac,
as far as I know, didn't come in a 100W model. I'd also be curious to
know if the lowband Maratrac will go to 6m and/or 10m. I know that the
m400 is NOT a good choice for ham-band use (see Batlabs for details).
According to my chart,

Hi Bob,
The R100 can be easily retuned to 70cm. Trick is, you must modify the RSS
program in a hex editor to allow programming of frequencies below 450 MHz. The
how-to for that is found at http://www.batlabs.com/r100.html. After modifying
the RSS, program your frequencies and re-align per
