• 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.

Anybody know who the first public safety user of UHF (450 to 470 Mhz) was? Maybe somewhere around 1960?

Boston Mass Police apparently went to UHF around 1972. Maybe 1970. Philadelphia Police might have been on 453 Mhz before that. Maybe NYPD and Chicago PD were on UHF before 1970 also. ???

According to this page (GE MOBILE RADIO HISTORY), GE made UHF radios (their Pre-Progress line of radios) starting in July of 1954. In 1955 they released the new "Progress Line" of radios to compete with the Motorola Twin-V series (the T44 models were their UHF versions).

I haven't yet found links to any of the early users of the UHF band, but this would have been in 1954 or so since that's when the FCC opened the 450 - 470 MHz band up to the land mobile users.

I once had a Motorola UHF base station that once belonged to a county agency in Southern California. Manufacture date of the radio was around 1956.

City of Atlanta PD migrated to UHF in 1970. Detectives remained on VHF, as did Atlanta fire until 1995 when the city purchased their first Smartnet II 800MHz TRS, and that system was replaced in 2009 with their Astro 25 digital system.

Maybe I can try to find some APCO Magazines from around 1954. Or some police or fire magazines. Maybe a local newspaper might have a story also.
