MTR3000 Programming and Tuning: Base Station/Repeater Tuning Setup 13-3
13.3 Base Station/Repeater Tuning Setup
A personal computer (PC), Windows
TM
operating system, and the MOTOTRBO Tuner application
are required to tune the Station. To perform the tuning procedures, the base station/repeater must
be connected to the PC and test equipment setup as shown in Figure 13-4.

13.4 Tuning Setup (MTR2000 MOTOTRBO Digital Upgrade)
13.4.1 MTR2000 Calibration Coefficient Entry
This feature is used to allow entry of the transmitter (Tx) output power coefficients of an MTR2000
Power Amplifier (PA) into the MTR3000 tuning codeplug.
Since an upgraded MTR2000 Base Station/Repeater does not have its PA upgraded, its PA
calibration coefficients must be entered into the tuning codeplug, as the non-upgraded MTR2000 PA
does not have an Electrically Erasable Programmable Read-only Memory (EEPROM). The
calibration coefficients, which exist on a sticker on the face plate, consist of two 7 digit hexadecimal
numbers and two 6 digit hexadecimal numbers. The sticker itself is created and applied at the factory
in which the PA was calibrated.

Section 13.4 on page 13-3 only applies to an upgraded MTR2000 Base Station/Repeater.
