Batboard

I was wondering if a Maxtrac model#D45MQA5GB5AK will do conventional 800mhz, and what type of antenna connector is on the radio?

Thanks,
Tony

I think the antenna connector is a "SMA" style. I don't know exactly what model that Maxtrac is, but I have a bunch of 2system/2fleet trunking radios that I wanted to do conventional. I went to one Motorola shop, and they said that my radio would not do conventional. The only trunking Maxtracs that would do conv. were the ones with the channel selector. I asked here and I was then told to blank the board with LAB RSS, change the firmware and use conv. software to program it. I don't have any RSS at all so I can't try it.

If anyone has Maxtrac LAB RSS, I would like to see if you could do it. If the radio dies, no big deal. I bought them for next to nothing on Ebay.

I'm pretty sure the connector is called a Mini-UHF. At least that's what Motorola refers to it as. SMA is for the newer portables.

The conector is a mini-uhf on all maxtracs. the B5 model is only a trunking radio. To use it on conventional, you were told right. You have to blank the board and make it a conventional radio or change it to a B7 model and put a display face on it. Takes Lab Rss to do this.

Can I reblank a 800mhz maxtrac as a 16 or 32 channel radio, conventional, that will do MDC decode? I know how to do the blanking, have done it before, Just need to know what settings have worked for people.

HI:

Before you get to deep, please be aware
that you should " Save " all the Transmitt
Soft Pot values.

Failure to observe that will make it very
difficult for you to realign the radio
back to normal, and using the default values
makes the radio just useable

Also, there is a Firmware Eprom that has
spacific instuctions as per the model number
of the radio you wish to make.

Also, using 800 Mhz Simplex Channels in the
US unless yu have a spacific license for the
operation could land you into some trouble with the organizations that have digital trunking in serivce....Operating on some of their freqs could make thier system inoperatable, and bring undue attention to the operator...

If its outside the US, then you only have to comply with the country its being used it.

Either way, you will be spending a nominal
amount of time getting the radios to due
simplex.

If you have the " 16 " Pin Series Logic
Board, you will have a much better chance,
but if they are the older 5 pin style, I would suggest a alternative,

If you need futher information, it would
be advisable to email me direct.

Hi Monty,

Just sent you an email.

It's to monitor a conventional system if that helps clear anything up.... it should be a B7 16 pin radio...

Hi:

This is just for the group.

There is a Major Difference in the
RF Boards between a B5 radio and a B7

The B5 uses a HLF4095B which is Trunking only

The B7 uses a HLF9122A which will do
trunking and talkaround...

Soooo, you will have to do more to a B5 series radio other than just logic board manipulation. The HLF9122 operates over
the range 806-825Tx / 851-870Tx for the
talkaround version vs the B5 which is
just 806-825.

The RECEIVER is limited to 851-870 Mhz
in BOTH series of radios.


Typical of ~//~ to make 2 different RF boards for the same radio !
