• 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.

Sounds like you are trying to program a UHF1 frequency into a UHF2 radio and it keeps defaulting to the low end of the band split

That literally answers your question. The radio is not capable of 444mHz
It sure is. I have several hi split 6550’s on 440-450 freq’s, & they work perfectly. A simple hex edit using regular CPS takes care of that problem. No “funny tools” needed. There’s hours of reading on that subject.

I'll add the caveat *as it is currently configured*

And specifications not guaranteed.
90% of the local Motorola ham DMR repeaters are 450-512 split. They are hex edited to work in the ham band. If one is buying new, one buys low split. But if buying surplus used, & only hi split repeaters are available, they get used with no degradation in service. The only problem with using a Hi split Moto repeater in the ham band is they won’t play with a Hytera radio. It’s not like we’re asking a 450-512 radio to work at 405 MHz. Just slide down another 10 MHz. Half our group is using hi split radios in the ham band, & no complaints. They were $100 cheaper vs the lo split version.

Ok, but specifications still not guaranteed.
