Model Charts
General Description
Programming,
Flashing, and
Cloning
Four model charts cover the three families of radios discussed in
this publication:
Conventional Systems Radios, HT 1000
Conventional Systems Radios, JT 1000 and MT 2000
Private Systems Radios
Shared Systems Radios
Each model chart lists the model number and its description,
and the three main radio components: the transceiver board, the
controller board, and the front cover. A single model may be
built using alternate controller boards and alternate transceiver
boards. The model charts will list all alternate controllers and all
alternate transceivers for any one particular model. Other model
components are referenced in electrical parts lists and exploded
view parts lists located toward the rear of the manual.
To determine which controller and transceiver is in a radio, that
radio must be opened and physically examined. Identification
kit number labels are attached to the controller board and to the
transceiver board.
All HT 1000, JT 1000, MT 2000, MTS 2000, and MTX Series
Radios covered in this manual are clonable. The JT 1000 Model
Radios are also front-panel programmable, and the MTS 2000
Series Radios are

“flashable.” The following cloning information
HT 1000 Model Radios:
VHF DN models cannot be cloned to AN, BN, or CN models.
Any DN model can be cloned from like CN or DN models.
Prior to cloning any AN or BN model into a like CN or DN
model, a code plug fix must be performed on the AN or BN
model. Failure to do so could seriously degrade the scan and
battery-saver capabilities of the CN or DN model radio. For
code plug-fix information, order Service Repair Notice,
SRN-1218.
Note: Cloning any AN model into a like CN or DN model will
remove the TEST MODE capability.

Performance Testing 3
General The HT 1000, JT 1000, MT 2000, MTS 2000, and MTX series radios
have been prepared to meet published specifications through their
manufacturing process, with the use of laboratory-quality test
equipment of highest accuracy. The recommended field service
equipment approaches the accuracy of the manufacturing equipment
with a few exceptions. Accuracy of the equipment must be maintained
in compliance with the manufacturer’s recommended calibration
schedule.
Setup Supply voltage can be connected from the battery eliminator. The
equipment required for alignment procedures is connected as shown
in the Radio Alignment Test Setup diagram.
Initial equipment control settings should be as indicated in the
following table, and should hold for all alignment procedures except
as noted in Table 4.

NOTE: This note applies to software version R02.09
and earlier. If the radio is placed in TEST MODE

with Option•Mate interface plug enabled
through the HT 1000 RSS, TX and RX audio
will be muted. Do not test Analog Voice
Security (AVS) installed radios in the TEST
MODE.
When the HT 1000/JT 1000 radio is operating in its normal
environment, the radio's microcontroller controls the RF channel
selection, transmitter key-up, and receiver muting. However, when the
unit is on the bench for testing, alignment, or repair, it is removed
from its normal environment. It cannot receive commands from its
system and, therefore, the internal microcontroller will not key the
transmitter nor unmute the receiver. This prevents the use of normal
tune-up procedures. To solve this problem a special routine, called
TEST MODE or “air test,” has been incorporated in the radio.
To enter test mode:
1. Turn the radio on.
2. Within ten seconds after the self test is complete, press the
monitor button (side button 3, SB3) five times in succession. After
the fifth press:
a. (HT 1000 radios), a tone is emitted to indicate that the rf test
mode has been entered.
b. (JT 1000 radios), the display will show the firmware version of
the microprocessor for two seconds, emit a tone, then display
TEST MODE).
3. Each additional press of SB3 will advance to the next test channel.
(refer to Table 6), and a corresponding set of tones will indicate the
channel.
4. Pressing SB2 will scroll through and access test environments as
shown in Table 5.
NOTE: Transmit into a load when keying a radio
under test.
To exit test mode, turn the radio off then back on.
