• 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.

Do commercial repeaters usually follow a offset for inputs like amateur radio repeaters do?
If they don't how would you be able to find the input?

Thank You

Only on 220 MHz and higher bands.
There are no standard offsets or channel pairs on VHF except for some of the paging channels and the 152/157 MHz business channels that were formerly used only by taxis. On VHF you find the input either by looking up the license or by searching.

220-222 MHz repeaters are -1 MHz offset
406-420 MHz repeaters are +9 MHz offset
450-470 MHz repeaters are +5 MHz offset
470-512 MHz repeaters are +3 MHz offset
764-776 MHz repeaters are +30 MHz offset
851-869 MHz repeaters are -45 MHz offset
935-940 MHz repeaters are -39 MHz offset

There doesn't seem to be any pattern at all on the VHF high band.

When I first started scanning in the 1970's, I don't recall any repeaters in the VHF high band for public safety. Since the band was already occupied when VHF repeaters became popular, it would have been difficult to establish a standard offset without relocating other users. This would have been a time consuming process at the time, when you consider the radios of that era were crystal controlled and trunk mounted.

Additionally, the band was dotted with different radio services...business, utilities, taxi service etc, that would have made it impossible to establish a standard.

The 450-470 mhz band is pretty much a 5 Mhz split, with the lower frequency of the pair being the transmit side of the repeater.
