ASTRO Spectra Firmware: ASTRO25 Trunking R10.72.00 / 08.03.05 
This CVN will update the 1MB ASTRO Spectra to the following firmware version:

Host: R10.72.00
DSP: 08.03.05

This firmware package is used for conventional and ASTRO25 (9600bps control channel) trunking operation. Limited 3600bps trunking features are also supported. Key-word: LIMITED.

ASTRO25 trunking is only supported on 800 MHz. No VHF/UHF support. This firmware hasn't even been tested on VHF/UHF conventional. Steer clear, unless you want to experiment or use for 800 MHz.

Note: Supports REBANDING.

For the overwhelming majority of users, this is not the CVN to use.

Note: DSP will automatically flash analog or digital, depending on your existing flashcode. (N08.03.05, A08.03.05, etc.)

The following hardware is required to utilize this flash file:

- Valid refresh iButton with remaining flashes;
- Motorola CPS or RSS (CPS R05.03.00 is recommended);
- Motorola SmartRIB (SRIB) with power supply;
- ASTRO Spectra Flash Cable. RKN4047A. Programming cables DO NOT WORK.
