• 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.

Crossband repeaters on Itinerant Frequencies?

I believe you're referring to VEHICULAR REPEATERS (See Pyramid and MSI) which are an approved and common use of cross-banding in Part 90. There's even an MO3I station class for an itinerant VEHICULAR REPEATER.
also called "mobile extenders" because they're located in the mobile (i.e. squad car) and they extend the range of H.T.s carried by police officers (while out on foot).

This further reinforces the need to check with the FCC or a frequency coordinator to make sure what is legal and licensable. It may be perfectly legal to cross band within a part 90 license but you might need radio equipment specifically type accepted for cross band repeater use. You can't guess or assume, you need to know and I don't think anyone here does.

I noticed an old Anytone 5888uv is Part 90, crossband capable in the covered frequency ranges. Would that not be acceptable assuming his license includes that station as MO3I?

I think only the FCC can answer that, all we can do here is guess. When doing research in the early 80s when putting together a GMRS repeater I read the radios used must not only be FCC type accepted for Part 95 GMRS but also for use as a repeater and the specifications for a repeater were tighter than just a radio. In other words sticking two mobile radios together was not legal unless the radios were FCC type accepted for use as a repeater. I have not been able to find that wording in recent searches but its probably still there.

All good points and I appreciate the input on this and I think it's a good conversation.

Something else occurred to me. IF it turns out he is OK to do crossbanding, is there a restriction on which particular itinerant frequencies may be used? I'm not familiar with if some of them are identified as simplex, repeater in and repeater out. Are they?
