5.2 Series II Radio Tuning
This section covers some basic Series II base station modules radio tuning and verification for:
- VHF (T83x-xx-0200),
- UHF (T85x-xx-0250) and
- 800 MHz/900 MHz (T88x-xx-0200).
Note: Usually, this section is not done unless called for in section 5.1 “Series II - Radio Programming”
or in
Table 9 “Checklist B” (General).
To identify the radio modules, check the part number on the manufacturer’s label at the back of the
Receiver, Exciter and Power Amplifier modules:
