Batboard

Hello all:

I've read the past posts about Flaxar radios (and how much they suck) but I have one as a "learning project" and I am looking for a copy of the service manual or any other information.

Does anyone have Flaxar documentation they can share with me?

Thanks in advance...

The radio part is just a Maxar and most Maxar manuals have enough info to get you started.

The Flexar manual is a collection of a lot of stuff, several bands for the RF and multiple options boards, about an inch thick.

If I have more info, radio range, and configiration, there may be just a few pages needed to get you going.

Perfect. Now I just need to hunt down a Maxar service manual.
Anyone know if I can still order one from MOL?

Rob, what frequency band/range is the RF chassis?

Hi Will:

It's an L43, so I'm guessing low power VHF?

Also, I'm a little confused... I was under the impession that this was a one piece box, but some other posts have stated this is a two box unit... with the duplexer in the second chassis. I only have the white plastic chassis, shown below.

L43TRK is a VHF 25 watt "Maxar in a box".

They came in three freq. ranges, 136-150, 150-162 the most prevelent, and 162-174. The freq range is determined by the RF chassis number.
TUD2121 136-150, 2122 150-162, 2123 162-174.

The four numbers after the TRK is the station option(s), and from the looks of the photo, you have a 3100.

31=PL, 61=DPL, 11 is Car sq

0= one freq, 3=two freq

0=local control

tow letters Aor B followed by H if it had/has a handset.

Yep...good guess just from looking...

It's an L43TRK3132AH.

For the number of these boxes floating around, it's a suprise there is not much about them on the web. I could find nothing on repeater-builder and only the few posts here on the batboard.

Any help or advice you guys can offer is welcome. (From reading some of the past posts, I have a feeling the first item will be, "Hey Rob, chuck it in a dumpster...")

Rob, Maxras were a good radio, just not top of the line. Mocom 70's had a better receiver!!

The two housings were only for the repeater version, I did not see any in VHF in my years at MSS/Motorola.

I can copy a few pages if you need.

I'd appreciate that.

My two bits worth:
Beware of the power supply in these!

There are two issues.
If the output regulator transistors short the radio will be supplied
with 24 V, which will fry many parts, I have seen one of these with a hole burnt thru the top of the case by the power transformer.
The customer was so impressed, they went out and replaced their entire system with compatitive equipment.

Early models needed modifications to ensure all the grounds, as well as chassis ground are the same.

Motorola used to have a campaign: Sell Flexar First! (That is the last thing you will sell them)

For all the grief that I have had with these critters, I have also seen many units still in service after 25 years or so.

There is a UHF repeater in my garbage pile as we speak.
