The XTL1500, XTL2500, and XTL5000 are three closely-related single-band mobile radios, all part of the Astro25 series of Motorola radios.


W3 Connections

See the Astro Spectra page for info.

Using a standard Odyssey TIB with a W3 Control Head

If you connect a W3 control head to a standard Odyssey-series TIB (p/n HLN6913, HLN6895, PMUN1036D, possibly others too), most functions will work without any issues. However you will not have transmit audio (a big deal if you're planning on using the radio to talk to people)

A simple jumper swap is all that is needed to restore TX audio

Dual Brick W3 Configuration

XTL5000 only

Two XTL5000 radios can be configured to run on a single W3 control head. This configuration requires special wiring of the remote head cabling, and specific codeplug and flashcode options. See the below guide:

Flashport Options

These radios share the common Astro25 flashport option set.

Out of Band

See the Hex-Edit Method. All three mobiles will operate in the ham bands without issues, although 900MHz models may exhibit some slight desense due to filter bandwidths.

W-Series Flashzap Mode

To put the W-series head XTL5000s into flashzap mode, the normal button combination does not work. Instead, you can connect to the radio serial port via a terminal program such as putty or hyperteminal. The command AT#FZAP=1 will put the radio into flashzap mode. However, please note that the head will show no indication of the radio state, and the only way to exit flashzap mode is to reboot. Proceed at your own risk, as the dirty flash method of firmware upgrading is even more risky with no indication of progress.

Debug Mode

Using the same console setup as above, entering the command AT&DEBUG will put the radio into debug mode. From this point, the ? command will print out available commands that can be used in this mode. Try it out!
