AN vs BN Radios
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. Earlier models of the XTS2500 and the Astro Spectra Plus are considered AN radios and are limited to the firmware version specified below.
Firmware
The latest firmware (as of 12/21/2016) is R20.50.08 for 8-meg BN radios and R09.00.41 for 4-meg AN radios.

Software
Astro25 radios program using the Astro25 Portable and Mobile CPS Packages. The portable version of CPS supports the XTS2500, XTS4000, and XTS5000. Astro25 Mobile CPS supports the Astro Spectra Plus, XTL1500, XTL2500, and XTL5000.
Amateur Use & Bandsplits
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. This is done using the Hex-edit Method which works for many CPS distributions, and detailed information can be found on the information page.
All Astro25 radios excluding the Astro Spectra Plus will tune to all frequencies in the amateur bands without issues. The Astro Spectra Plus VCO will not lock on some frequencies far from its rated band and requires a hardware mod to allow it to lock properly at these frequencies.
Single-Zone FPP Setup
Contrary to other reports, it is possible to set up a radio running BN firmware (R10+) for only a single zone of FPP channels, as opposed to 16 zones with 16 channels each. The way to do this is not immediately obvious however, as it may seem like all zones are locked as FPP only. The "gotcha" here is that any FPP zone must be preceded by only other FPP zones. I don't know why Motorola decided to do it this way, but you can't just take any zone in the middle of the codeplug and make it FPP or non-FPP.
Starting with a codeplug that has all 16 zones set up for FPP (meaning you also have 128 personalities - yikes), the procedure to get to a single FPP zone is as follows:
- Start from zone 16. You should be able to uncheck the "FPP Zone" field. Once you acknowledge the warnings and this is done, the 16 personalities assigned to that zone should be deleted and the codeplug structure will have been reopened.
- Now you should be able to delete zone 16.
- Follow the above procedure for the remaining 14 zones (zones 2-15)
- You should be left with a single FPP zone and 16 un-deletable conventional personalities. Configure these however you like per your FPP preference.

Astro25 Tuner Virtual Com Ports
Astro25 Tuner is known to have issues with reading & writing with higher COM port numbers. Ports above 20 appear to cause issues and give errors such as "Read Radio Failed." If you encounter issues, try lowering the com port number of your virtual com port.
