If you have a radio whose bandsplit is outside the amateur bands (a UHF-R2 'S'-split radio for the 450-520 MHz band would be an example) you must modify the CPS executable to allow the software to accept frequencies which are out of band for the model. Astro25 Mobile CPS supports the Astro Spectra Plus, XTL1500, XTL2500, and XTL5000. The portable version of CPS supports the XTS2500, XTS4000, and XTS5000.

The latest firmware (as of ) is R20.50.08 for 8-meg BN radios and R09.00.41 for 4-meg AN radios. Earlier models of the XTS2500 and the Astro Spectra Plus are considered AN radios and are limited to the firmware version specified below. Several radios in the Astro25 line are considered 'AN' or '4-meg' radios and contain a smaller flash rom chip (4 megabyte vs 8 megabyte) and are more limited in firmware and feature support.
