• 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.

it uses the licensed frequency of the agency you are monitoring. can be VHF, UHF, 800 mhz or 900 mhz, all depends on who has that system and what they needed.

Any frequency with emission designator 7K60FXE is a good start albeit certainly not all inclusive. Entities do change radios without chaning license info sometimes. Also some licenses have multiple modes on them some of which may not be or may never become active.

Your best bet generally will be UHF. There is a wiki article that is kept pretty current called MOTOTRBO that has a list of all MOTOTRBO licensed systems...

I find searching small ranges at a time (such as 420-430, 430-440 etc etc) helps nail things down. Listen for the occasional 'braaaap' of digital that TRBO systems generally give off every 10 seconds or so.

Mototrbo repeater / on channel or are two freqs.

Is Mototrbo capable of on channel repeat? This means no duplexers needed, just one licensed frequency.
The radios and repeater are on same frequency, just time division seperated.

If not, why?

No. And I would say because the Transmitter would desense the Receiver and the Receiver recovery time is a lot longer that the time slot.

Mototrbo?

I'm not sure if this is the right area to ask/post this but.
Has anybody in southern New Jersey shore area logged some sorta of "noise" on 152.030?
It's suppose to be one of Morey's Pier frequencies, but I'm not sure considering the strength of the signal in the AC area.

I think you mean 153.020. It is part the new AtlantiCare Medcom MOTOTRBO wide area system. Morey's Pier is also licensed to that frequency.
The site location for the MOTOTRBO freq. is Ocean City.

The receiver recovery time is not longer than one time slot. Otherwise, transmit interrupt would not work. Technically, it is possible to run 'full duplex' using TDMA. That's how TDMA cell phones have worked for years. So, it should be possible to do an 'on frequency' repeater, too, repeating between the two time slots.
