I was just given an XTS2500 to test P25 with, but of course it would not accept the ham bands on 900 MHz. This required editing the values in the PatPort.exe file in the Astro 25 Portable programing software. I've not tried the Tuner, but assume it would be the same.

If this is you, here's what needs to be done if you want to have FPP out of band (say on 902 MHz). BTW, FPP sucks ass (aka a rimjob) on this radio.
- CPS/Depot needs to be modified to allow ham band frequencies to be programed in the CPS.
- The radio must be modified to change the FPP limits in the radio using flashzap.
- CPS/Depot needs to be modified to not correct any FPP band limits it finds in the radio when programing it. This prevents CPS from "fixing" what's been changed on the radio when reprogramming it.
Or, don't understand shit, and just download the already edited patport.exe and use that.
Changes to PatPort.exe
For 20.01.00
Offset | Original Frequency | Original Hex | New Frequency | New Hex |
---|---|---|---|---|
0x1200CE8 | 901,987,500 | AC3C C335 | 907,987,500 | 2CCA 1E36 |
0x1200DDC | 935,012,500 | 9428 BB37 | 926,012,500 | 54D4 3137 |
0x1200ECC | 935,012,500 | 9428 BB37 | 926,012,500 | 54D4 3137 |
0x1200F1C | 935,012,500 | 9428 BB37 | 926,012,500 | 54D4 3137 |
0x120134c | 935,012,500 | 9428 BB37 | 926,012,500 | 54D4 3137 |
0x120139c | 935,012,500 | 9428 BB37 | 926,012,500 | 54D4 3137 |
Feel free to put the new frequencies to what ever you want, but I've chosen here to give the standard 25 MHz ham split. I'm not sure what is the Talk Around and normal tables here, but if you find it please add to this wiki.
For OOB FPP to work the code must be changed in patport to cause the bytes to not be re-written. 0x3df2e5 - change 74 to EB
Any FPP band edges modified using flash zap will then work after programing with CPS.
FPP is kinda gay though.

Blocks
FlashZap reads out in decimal numbers.
FDB block 4100 is the serial/model number.
0x052/0x53 (82/32d) are the FPP band limits.
Example blocks:
82d - Receive Range | Multiply the long by this to get frequency in Hz 00 00 00 08 00 05 00 01 < one range 0B256E84 0B37AA7C - 935,012,500 - 940,987,500 CF 60
83d - TX Range, Primary and Talk around | Multiply the long by this to get frequency in Hz 00 00 00 08 00 05 00 02 < two Ranges 0AAE69C4 0AC0A5BC - 896,012,500 - 901,987,500 0B256E84 0B37AA7C - 935,012,500 - 940,987,500 4A 12 - Checksum
To cover the hamband I'll come down 2 MHz from either edge:
82d 0B09ED80 0B37AA7C - 926,000,000 - 940,987,500 83d 0AAE64E2 0AC6CA00 - 896,006,250 - 904,000,000 0B09ED80 0B37AF5E - 926,000,000 - 940,993,750
Be sure to recalc the block checksum after changing each. If you hit the radio with a non-modified CPS you will revert these changes.
Hardware
Several of the XTS2500's on the market have a dim keypad. Here's how to fix that
Universal Side Connector
aka xts2500 pinout or accessory connector.
