XTS 2500

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.

Changes to ParPort.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

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.

Blocks

FDB block 4100 is the serial/model number.

0x052 (82/32d) and 0x53 are the FPP band limits.
