Motorola equipment, follow the link you like the most!! They are truly "Deep In The Heart Of The State Now your CPS package will accept frequencies up to 480 MHz on a 403-470 radio.It's gotta be Motorola. To perform the switch, open up the executable and run a search and replace function to replace every occurance of 80A1031C with 00389C1C. Let's say you wanted to increase the upper limit to 480 MHz, or 480000000 Hz.

The band edges are stored in units of hertz, so for instance an upper band edge of 470MHz would be stored as 470000000 Hz, and in intel unsigned long format this would be 80A1031C. The short version of what you need to do is spelled out below.įor most CPS packages, the bandsplit numbers are stored as intel unsigned long hex strings. The Akardam website has a very in-depth and helpful article on changing the band limits for Motorola CPS packages, diving deep into the theory behind the mod. The use of a hex editor such as HexWorkshop or HxD is required, but the process itself is fairly straightforward.


Because of this, changing the band limits to allow for amateur frequencies can be slightly more difficult. Some RSS packages will give a warning about out of band performance, but for the most part you can ignore this.Ī partial listing of known RSS packages that support the shift-key method is shown below.įor some DOS RSS packages, and for almost all newer Windows CPS packages, the band limits for radios are stored in hex within the executable file itself. Note that you must fill out the entire field while holding the shift key, including adding extra zeros as necessary until you run out of space. At first this will appear as though you are typing jibberish into the frequency field, but it will automatically change to the entered frequency when you exit the field. Out of Band Radio Support Motorola Radios Jedi Seriesįully working, hex-edit method with hardware modĪPX radios are firmware locked to in-band onlyįor early DOS-based software such as the Maxtrac and Visar RSS packages, entering out of band frequencies is as simple as holding down the shift key while entering your desired frequency.
