1.5.2 Model Designation
To correctly identify your Paragon
PD
unit, check its catalog number label located on the rear of the
BDLC
PD
adjacent to the power connector.
The first four digits designate the model:
-
BDDD = Paragon
PD
(DGFSK)
-
BDD4 = Paragon
PD
(SRRC4FSK)
The next three digits designate the Band used:
- 83X = VHF, 100W
- 85X = UHF, 100W
- 88X = 800 MHz, 70W
The next digit designates the RF band of opera-
tion:
For the 83X band:
- 1 = 136 – 156 MHz
- 2 = 148 – 174 MHz
For the 85X band:
- 1 = 400 – 440 MHz
- 2 = 440 – 480 MHz
- 3 = 480 – 520 MHz
For the 88X band:
- 1 = 800 – 880 MHz (RX
850 – 870 MHz (TX)
- 2 = 870 – 960 MHz (RX)
(TX, 5W only)
The next digit designates the RF Bandwidth
used:
For the 83X band:
- 0 = 25 kHz full channel, 2.5 ppm*
- 5 = 12.5 kHz half channel, 2.5 ppm*
- 6 = 12.5 kHz half channel, 2.0 ppm* (U.S.
model only)
For the 85X band:
- 0 = 25 kHz full channel, 1 ppm*
- 5 = 12.5 kHz half channel, 1 ppm*
For the 88X band:
- 0 = 25 kHz full channel, 1.5 ppm*
- 5 = 12.5 kHz half channel, 1.5 ppm*
* denotes Frequency Stability
The next digit designates the transmitter power:
- 005 = 5 watt transmitter
- 070 = 70 watt transmitter (850-870 MHz
only)
- 100 = 100 watt transmitter
The next and last digit designates the Power
Source:
- 0 = Power supply deleted on order
- 2 = heavy-duty 120 VAC dual supplies
1.6 Radio Series I or II
System-engineered installations use one of two
complements of Paragon
PD
radio modules. To
identify the radio series model, check the part
number on the manufacturer’s label at the back
of the Receiver and Exciter:
- T8nn-nn identifies a Series I model.
- T8nn-nn-nnnn identifies a Series II model.
where “n” denotes a number.
Examples:
- T881-10 is a Series I Exciter (850–870 MHz)
- T881-10-0000 is a Series II Exciter (850–870
MHz)
They are assembled on a common chassis:
Series I models:
- 800 MHz frequency range radios
- Frequency programming is done via
EPROM. (This model does not use the pro-
gramming port of Series II models).
Series I models will not be available after the Series II
models receive FCC’s and IC’s approvals.
Series II models:
- VHF and UHF frequency range radios. The
800MHz Series II models are pending FCC
& IC approvals.
- Frequency programming is done using soft-
ware via a programming port located on the
speaker front panel.
