But at that they do need mods, mostly the front end helicals have to be changed, and the mods only work on certain models. I don't think there has been much success moving the transmitters up at all.

Re: [Repeater-Builder] Maxtracs as Repeaters, some Questions (no flames included)
Go to (www.batlabs.com)
for real good info. Just a reminder that the 800 MHZ are wide band IE: 5 kz the
900 MHZ is mostly 2.5 KZ. You can buy already converted and programed 927 Ham
band stuff from Cook Towers.
They have Maxtrac's GTX's and outher mother M stuff for the
927 Ham bands.
NO I DO NOT WORK THERE. Just for info. BTW they are very nice
folks to deal with.

Hi

As the title suggests, I
have a couple of questions about the use of Maxtracs as repeater radios,

All the time. If yours will
allow you to program the pins .. its easy. I have used S-com, and Link-Comm
controllers on Maxtracs, CDM series, GM series
radios.
1. I've seen the MRT
articles for linking 2 maxtracs together, besides theRICK and these
adapters,has anyone rig a full blown controller, say a Scom 7k to
these bad boys using the 16 pin plug on the
back?
2. Under the software
control of these radios (RSS) can the RF power out be dialed down low
enough as not to mess the finials and still drive an external PA?
Low enough maybe to drive a Micor 60-100 PA. (In the Micor, if you
turn the power down to low the finals don't like it... a
lot!)
Is your radio a 40 or 45
watt version ... then it will only go down to 20 watts and still hold specs.
If it is a 20 watt version, then it will go all the way down to 1
watt(model # beginning with D44 is UHF high power, D43 is VHF hi power,
D33 is VHF low, D34 is UHF low)
3. Not being as robust as a
micor/mastrII, what about heat, cooling, fans? Do these radios have any kind
of continuos duty rating?
I use cooling fans on even
the ones that are just link radios. I also run them at 20 watts for hiigh
power units, or 10 watts for low power units.
4. Some have called these
radios "barn doors" for being so wide open on the front end. Has this
been a problem? Can they be preselected? This was a good thing
on the Micors!
I preselect them using
bandpass cavities, or you can use the DCI filters or celwave preselectors
(the latter mentioned is sold as an option with this type unit for repeater
use.)
5. What other pit falls
have I missed?
Check the PA transistors, I
usually resolder them with silver solder. If you do not do this, and they
get a little too warm, they will unsolder themselves. The silver solder
gives you a little more temperature range.
A couple of Club members in
our weather spotter group are crossbanding an UHF to VHF maxtracs to get
