• To anyone looking to acquire commercial radio programming software:

    Please do not make requests for copies of radio programming software which is sold (or was sold) by the manufacturer for any monetary value. All requests will be deleted and a forum infraction issued. Making a request such as this is attempting to engage in software piracy and this forum cannot be involved or associated with this activity. The same goes for any private transaction via Private Message. Even if you attempt to engage in this activity in PM's we will still enforce the forum rules. Your PM's are not private and the administration has the right to read them if there's a hint to criminal activity.

    If you are having trouble legally obtaining software please state so. We do not want any hurt feelings when your vague post is mistaken for a free request. It is YOUR responsibility to properly word your request.

    To obtain Motorola software see the Sticky in the Motorola forum.

    The various other vendors often permit their dealers to sell the software online (i.e., Kenwood). Please use Google or some other search engine to find a dealer that sells the software. Typically each series or individual radio requires its own software package. Often the Kenwood software is less than $100 so don't be a cheapskate; just purchase it.

    For M/A Com/Harris/GE, etc: there are two software packages that program all current and past radios. One package is for conventional programming and the other for trunked programming. The trunked package is in upwards of $2,500. The conventional package is more reasonable though is still several hundred dollars. The benefit is you do not need multiple versions for each radio (unlike Motorola).

    This is a large and very visible forum. We cannot jeopardize the ability to provide the RadioReference services by allowing this activity to occur. Please respect this.

I have an old Mt-1000. It has 8 channels, and works pretty good. it has some old security fequencies in the UHF band. How can I tell exactly what the coverage is?

Model # is H44GCU7180AN

Any help would be greatly appreciated.

Thanks
Mark

Unless you know what frequencies are programmed in it already, you will have to dismantle the unit and get info from the RF board in order to know what UHF split it is.

Could be 438-470MHz but not sure. If you knew just one frequency it would help

I know one channel is programmed for 464.325. I believe the others are all fairly close to that. I'll have to check it out a little further.

look at the inside back of the radio and get the model number. Call a Motorola tech and he/she will be glad to give you the frequency range of the radio. It is actually THAT simple.

It's actually not that simple. Not with the HT600/MT1000 radios.

The model number would decode as "UHF" 403-520 or whatever the max split of the entire radio series in UHF was. The radio is actually a sub-split of this.

from HT600/MT1000

"HT600 Bandsplits

Again, there are only two ways to determine the bandsplit in the radio. You can read the radio with the RSS, or open the radio and look at the split printed on the VCO board.

The available bandsplits for these radios is as follows:
VHF UHF
136-151MHz 403-433MHz
146-152MHz 438-470MHz
157-174MHz 470-500MHz
488-520MHz"

And there it is.

If he has freq's similar to 464.325mhz, I'm pretty sure that the freq split of the radio is UHF-Lo2 (438-470). Other than that guess work, opening up the radio and looking at the RF board or reading the radio with RSS will determine the bandsplit.

If it is a 464 radio, then the bandsplit is 438-470. They don't really go "out of band" well, from what I've read which has got to be a plus on the selectivity standpoint.

If you were to call Motorola and give them the Model number and Serial number they can look up the record without taking appart the radio. The other option is goto a local Motorola dealer and have them connect the programmer to it and they can tell you what is programmed in the radio.

If one frequency is around 464 then the band split is 438-470MHz
