• 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.

Master IIIs are a bit vintage but there are some still in operation. Base/repeaters are like a short rack cabinet to several 6 foot racks.
Mobiles are getting rare and hard to find, maybe a search on ebay or poke around ham fests.
Questions you can post here.

I left GE when Mastr II mobiles were replaced by Deltas. Unless Mastr III mobiles existed in the lab, don't believe they were ever manufactured. Rangrs were a cost improvement project on the Delta and manufactured by Hatachi for GE/Ericsson.

BTW: I have numerous clients with Mastr III base/repeater systems still in operation. Really hard to find replacement modules especially the final amplifiers that were manufactured by Crescend. They are all resorting to canibilization.

It was a great station manufactured in two versions pre and post 2004. The post 2004 (digital ready) is the one to find.

Make sure the all MIII's are post 2004. They are labeled on the front panel "Advanced digital..." The main difference are portals after transmitter pre-emphasis and before receiver pre-emphasis so you have a flat frequency response.

You stated P-25. They can be simulcasted but the non-linearity of the transmitter signal (class C amplifier) will require the inter station difference to be 9-10 miles maximum.
