Surplus Radio Guide Series, Programming Motorola Maxtrac & Radius models 

Please keep running this programming series, it is very interesting mate! I hold a UK intermediate Amateur Radio licence and I am particularly interested in converting business radio equipment to Ham use. So far I have "done" Kenwood TK350 hand held's and a couple of Maxcom PM100 mobiles. I also have the ubiquitous GP300 handheld but I only have programming gear for the Kenwoods. Bye the way I have recently put my first two videos on RU-vid - please take a look and comment!

Been a whilst since I've seen power menu lol, I'd forgotten about it till just now. It was a great menu system in it's time.

wow pretty good teachings! thanks man.

Thanks for this vid..Great job..Learning this stuff

You will have a to have a later version of the the SM50 program so it will read the radio...

its a sense ignition you can jump it inside so dont need a wire connectet to 12 v

Would it be the same for the maratrac?

Hey Bro wicked video been retired awhile and started getting into the Radio thing .. been a computer nerd since 91 ...dos and all . pretty good at it got an old motorola maxtrac out of my welding truck... model D33MJA7JA5AK . IM Guessing its 136-174 Vhf it has more than 8 channels programmed My question to you is .. where do you get the mic cable , black box , and the other box .. and the software download , ? ..I got nothing but time .. my radio powers up.... works ....might need new mic in future but ya .. wicked man ...dont like to talk on the radio..... just the tech stuff.. Thx ... Canada out

Good morning guys. I just had a someone program 4 Motorola HT600's to communicate with each other. I am looking for a Maxtrac that works and can be programed to communicate with the HT600's. These are the same radios I used when I first became a Sheriff. Also, I am looking for a cloning cable for the HT600's, that goes from Radio-to-Radio, not Radio-to-computer. Thanks for y'alls help.

More than likely the last radio you show in the video was programmed by a newer version of RSS. tis is Motoroni's way of making one buy newer programming software. Their new windows based software is nice but from what I gather very hard to modify when one needs to get into the meat and potatoes of changing the bandwidth parameters of a radio unlike the DOS programs where one could change the frequency range of a radio.

That rib box programs the maxtrac gm300 m120 radios also the gtx900 mobile they are all radius series mobiles. The maxtrac the gm 300 and the m120 are all the same radio. The gm 300 was a 2 channel a 8 channel or a 16 channel the m120 was 2 channel only I believe and the maxtrac was 2 8 or 16 or 32 channels. The maxtrac was also trunking capable on the original 800 mhz trunking systems it is NOT p25 trunking.

There should be a jumper in the radio to disable or enable ignition.

Got a Question, that I hope you can answer I want to add a new ch to a M1225 on the 2 m ham band I just can't remember how to take it out of band. I thought it # and then the freq. Bill WB9SWR

can anyone point me in the right direction of finding all the cables to program a maxtrac 100?

Can u give some info about Power Menu??

I have a maxtrac 300 low-band on 6m question . I use alot m120's, gm300 all time used repeater adapters from Amazon so they repeat . I have also couple radios cross band . I have no issues ever perfect audio all time. Well here's the issue the 6m low band I have works perfect after tuned and brass slugged. I had no pin 8 Cor but programing it fixed that. Now when I put it together with any UHF radio as a remote link guess what... The tx flat audio out is high pitched and low in volume then a r radio as I break the sq and then key up on 6m ht . I just spent a few hours trying capcitors, transformers across the pin 5 audio to source out no good . I changed a few settings in menu extended features key f9 after reading no good . It's almost like I need a preamp with tone control to deepen the squirlly audio. What's your take on that i tried naxtrac into 2 m10's ,2 m120"s ,1 gm309 UHF , 1 vhf gm300 all hi pitched naxtrac"s pin 5 tx audio into other radios thin hi pitched lower audio . The repeater adapters I have two that don't help the audio either it's like a misunderstanding matched tx audio out to other Moto radios? Frustrating.

Just to note - 800 MHz is not legal for anyone to use in the USA except law enforcement and some commercial users that still have license. You should NOT have to adjust the ref osc. unless you recapped the PLL section or did a board change, otherwise you really should not be messing with it. Your Maxtrac has a hacked or bad codeplug in it = double high low POST beeps.. The SM50 as well as the SP50 (handheld version) are no longer legal to use in the US on part 90 bands due to narrow banding. Ham and GMRS radio they are OK to use because they Sm50 and SM120 and SP 50 have part 95 certification. SM50's are good for building compact 25 watt repeaters but I would recommend the PM400 (UHF) / CM300 (VHF) for a more modern build in the same form factor ERROR 22 Radio Not Supported = The SM50 can not be read with the SP50 RSS, You need SM50 RSS. The SM50 and SP50 are part of the same product line but Motorola made separate programs for them. USB based cables WILL NOT work reliably and can brick the radio

Always good info on your videos Whst ever happened to the simple repeater you left on the mountian

Where would one find the Maxtrac software?

Why does the rib need 9 volts?

Where do you get the hardware interface cables / boxes???

Where do I download the software?

Anyone have download links for Motorola CPS? I have cdm 750 I would like to program.

Hi, Have you ever programmed an out of band radius gp300-5t portable please?

I have Rss on a cd rom and used it back in the late 90s early 2000 to program some maxtracs but cant remember what machine I used to do it. Is it possible that the software is windows based since it is on cd rom? I don't remember using dos but may have. Any chance you could jog my memory and tell me what i need to do? I have the rib, the cables and software just confused with the software being on a cd.

Do you have a video for an old MCS2000 VHF Model? Trying to set one up for 2M Ham radio, can't get the software to talk to the radio @Guerrillacomm

You are using the RSS for SP50 not SM50. You need the proper RSS.

can i have a software

I have a 16 channel MaxTrax on 45 Mhz. Can you modify for 32 channels and program for 6-menter? If so, please provide your contact info and address so I can send it to you. Thanks, Joe (WD8BVL)

Hy, my model: D34LRA73A5AK works on frequencies 449.0 - 470.0 Mhz I'm trying to drop on the Ham band 430.0 Mhz, I need a RSS program for MaxTrac R07.02.00A or a modified radmbl.mdf that supports lower frequency programming .. can anybody help me? 73 de 9A6GEZ.

Hey GUERRILLACOMM I have some Moto. Maxtracs 440 that i need programed. Do you think the USB Rib you see on Ebay will work?

tons of bad-information here just to let you know

After you download dosbox how do you open the software in dos box

I need program software for motorola mostar.. Any info. of where i can get it? Thanks

I like the Kenwoods because you can use windows based software and make/save data sheets for all of the tx/rx frequencies and details. DOS sucks!

This is what i purchased, is it the correct RIB box programmer for the GM300? And if i understand correct, the DB-25 is where a cable is connected to the RJ-45 microphone connector with a modified RJ-45 with certain pins so the RIB box can communicate? Can i use the Radio Doctor program to program, or program exactly, please? Thank you.www.ebay.com/itm/271591474675?euid=f300a0bd863742c4b07bde4413596e28&bu=43476121132&cp=1&sojTags=bu=bu
