T800-30-0000 & T800-30-0002 DFSK Modulators
The T800-30-0000 (formerly T800-30) and T800-30-0002 (formerly T800-35) are DFSK
modulators for T800 Series II transmitters, suitable for POCSAG or similar paging data
formats. Analogue transmissions (e.g. tone or speech) are still possible by disabling the
data path via a control line. 512 or 1200 baud data rates are link selectable. The
T800-30-0002 is adapted for use with an external reference oscillator for simulcast trans-
mission. The T800-30-0000 and T800-30-0002 are not designed for use with 66 to 88MHz
equipment.
Refer to the T800 Ancillary Equipment Service Manual for more information.
T800-32-0000 & T800-32-0010 DFSK Modulators
The T800-32-0000 and T800-32-0010 are DFSK modulator PCBs which can be fitted to
T800 Series II transmitters to enable them to function as low-speed paging transmitters.
These new PCBs have been specifically designed for Series II transmitters and will be
much easier to fit into the latest design transmitters.
Both PCBs are suitable for POCSAG or similar paging data formats, but are not
designed for analogue transmissions (e.g. tone or speech). The T800-32-0010 is adapted
for use with an external reference oscillator for simulcast transmission. The T800-32-
0000 and T800-32-0010 are not designed for use with 66 to 88MHz equipment.
