• 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.

My HT1250's will do at least 450-490. High UHF split radios do not go below 450, so you can't use them on 440.

Low UHF split units will not go over 470 but will do the 440 ham band.

I haven't tried going over 490 on my HT1250's since my area doesn't require that.

One of my HT1250 model numbers: AAH25RDF9AA5AN

The "R" in the 6th position designates 403 - 470 MHz
Radios with an "S" in that position designate 450 - 512 MHz

Yes, a "S" split radio will go as high as 512mhz. Though, there isn't much up that high in most areas, congested areas such as high population cities will probably use frequencies up that high. Technically speaking, all HT1250's can DO 403-512mhz its just a matter of reliability of the RF section of the radio, since 403-470mhz radios aren't designed to be used up that high, problems such as poor Rx, poor Tx or VCO unlock can occur, and visa versa. Of course, this is not to mention the firmware and codeplug modifications that need to be made to force the radio to do the different split.
