    Default HPD 1000 Radios?

    Does anyone know what series the HPD 1000 radios are from or related to? I'm interested as to how Motorola solved the "Class-C" PA problem with 16- or 64-QAM, as well as the baseband signalling rate that develops a 17K7 transmit mask. Is this radio available on bands other than 800MHz? (I suspect being 17k7 emission mask or 25 KHz channels, the answer is no).

    My gut feeling is that they went with a linear PA and the idle current is high on this radio; can anyone confirm that? Is there a manual for the beast, and if so, what's the price?

    Just put the googler on it:
    http://www.motorolasolutions.com/web...n_Brochure.pdf

    Looks like the HAI version (HPD air interface) is only licensed for 794-824.

    You can get more info from the FCC's site:
    http://transition.fcc.gov/oet/ea/fccid/
    FCC ID is AZ4 92FT5850

    Idle current is about 1.2A.

    I'm not sure if this answers your question, but the HPD 1000 is part of Motorola's "High Performance Data" system (HPD), which is the replacement for the aging RD-LAP system. The radios are used in vehicles (police/fire, for example) to interface to the data terminal or computer in the vehicle for license queries, etc.

    They communicate with GTR series base stations.
