• 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 know about Trisquare, Nextel Direct Talk, and Motorola DTR series using 902-928 mHz. What other portables are using this band for two way communications?

Its a part 15 license free band in addition to an amateur band but very few 900MHz amateur radios are made. I have an Alinco DJ-G29 that does 902-928MHz and a lot of people modify 800MHz commercial equipment for the 900 amateur band.

I have about 50 of the standard HX587T. A FEW Visars and Maxtracs for 900. I was a sales mgr for a radio company that owned trunking systems all over the US. We used these for out 900 community repeaters that operated in the southern states. We had good systems that covered from Slidal, La, New Orleans to Baton Rouge. Had a bunch of Johnson flip type radios, but threw them away. Standard covers the ham band though had to play around alittle. Units are software programed.

Since there is no Part 15 forum, and the OP mentioned the TriSquare and Motorola DTRS Part 15 radios, this is probably the best spot for this thread.
There's no MURS forum, either, but since MURS is Part 95 alongside FRS/GMRS, MURS threads get lumped in here as well. (Probably better than getting lumped into the CB forum.)
Anyway, I thought Hams modified 935-940 MHz radios down into the 902-928 MHz band? Or is it both? 800 MHz radios get modified up into and 935 MHz radios get modified down into 902-928?

In my personal experience, 900 MCS2000's, GTX's, 9250's & most Jedi's go down to 902/927 no problem & well within spec. 900 Spectra's need a VCO mod to work there. The only 800 radio that goes up to 900 is a 800 Maxtrac, but only the receive in repeater use. The 800 Maxtrac will not tx in the 900 spectrum.

I guess we will just have to live with this forum being a catch all for non-GMRS discussions.I asked for it to be moved but no word yet.

This may come as a shock but there are other brands than /\/\.

Except for radios like the low power Trisquare, you have to have an FCC Technician license to use the ISM band with a radio with any power. There is lots of experimental things going on there, but you will need a ham license. Also, 900 MHz is very much line of sight, even a tree can stop your signal.

The others have been moved to off-topic wireless

The TriSquare (which is out of business) and Motorola DTR radios cannot be programmed with different frequencies. They are preset with the FHSS simplex only frequencies and .5 watts. I don't know a Ham that would want a .5 watt radio.

DTR are 1 watt. I know hams that have talked around the world on 1/2 watt

Trisquare is out of business. So scratch them off this list.

My comment consisted of 3 seperate paragraphs. The 3rd paragraph was in response to prcguy's comment about 800 MHz commercial radios being modified for use in the 902 MHz Amateur band. It was not intended to suggest that Ham's should attempt to modify TriSquare eXRS or Motorola DTRS radios in order to operate under Amateur rules, instead of Part 15 rules.
And even though I am a Ham, I also believe that CB, 49MHz, MURS, FRS, GMRS and eXRS/DTRS radios have a place, and are useful within their limitations.
