• 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 work for a PS agency that uses Motorola Type 2 Smartnet trunking for statewide ops and conventional regional repeaters at fixed sites. I am also a HAM and I want to dabble in 900mhz. I recently acquired an MTX9000 B3 unit in working order. I have seen a couple of good How To-s describing how to open up the 900mhz HAM segment of the band in these radios. I would also like to open up my work site repeater and the trunk network as well if I can. Anyone know whether these 900mhz units can stretch down to mid 800mhz with a codeplug hack?

No - they won't go down that far. Even if you could do a rss hack the VCO will not lock
that far away from the intended 900 freq range.

You will need an MTX8000 for that lower freq range.

not only the VCO but the RF amp will not work (it falls off rapidly in the 925 area). The same for the rx front end although it isnt as noticable.

Unfortunatly for 800meg you will need a 800 meg unit. There are lots of 800 MTSX series untis available.
