Guide to ASTRO Digital Radios
With this said, the Motorola Inc. ASTRO25 line has been compromised. There exists a very
covert market which offers XTS 5000 portables with nearly all FLASHport features enabled, latest
host and DSP firmware and legitimate serial numbers. While there is no definite source for these radios,
they do appear for sale on eBay and certain radio-related Internet discussion boards from time-to-time.
The value of a featureless XTS 5000 with old host and DSP firmware (anything below R07.xx.xx) is
about $1000 US.
Meantime, a feature-rich XTS 5000 with the latest firmware can easily fetch $2000 or more.
Some hobbyists dispute this price, but if you want to play, you’ve got to pay. The main incentive of an
“enabled” XTS 5000™ is the FLASHport Q52 feature, which is a restricted US Government Front Panel
Programming option. This allows the radio to be programmed without the need for a computer. This
option supports conventional programming onlytrunking systems cannot be manipulated by Q52.
The Q52 FPP menu allows a user to change the transmit and receive frequencies, the transmit
and receive PL/DPL tones, the transmit and receive Network Access Codes (NACs) which are used for
ASTRO transmissions, the transmit and receive modulation types (analog, digital and mixed), the
transmit and receive bandwidth and the channel and zone names.
Figure 6.2 A sampling of some of the various options which can be changed via the Q52 FPP option in the Motorola Inc. XTS 5000 portable
radio. The FPP option is available for VHF, UHF and 800 MHz models. FPP ranges are the same as what may be entered normally in CPS.
Despite the contrary information on certain Internet discussion forums which suggests Q52 and
H37/H38 (trunking) options cannot be in a radio together, this is untrue. There are several Q52 + H38
(SmartZone) radios in existencebut again, trunking is not user-programmable via the keypad.
FPP+trunking radios are NOT offered legitimately through Motorola Inc. at the time this guide was
published. This is a stable “community hacked” feature.
