The SYN II Synthesizer is designed to operate over a frequency range of 140 to 149.995 MHz in 5 kHz steps and is compatible with two-meter equipment using transmit crystals in the 6, 8, 12, or 18 MHz range, and receive crystals in the 15 or 45 MHz range.
The synthesizer may be used with either FM or phase-modulated transmitters and with mobile or base transceivers. The SYN II features unique IF programming which permits the unit to be used with
receivers having IFs in the range of 100 kHz to 30 MHz. Detailed programming instructions are given in the construction manual so that the builder may select the standard 10.7 MHz IF or any other IF frequency in the permissible range, permitting use of the SYN II with older commercial equipment as well as currently available two-meter units.
Standard repeater offsets of +600 kHz and -600 kHz are provided, along with three user-selectable offsets in 100-kHz steps, permitting the user to operate into standard repeaters or with unique offsets. A modification kit is available for MARS and CAP offsets.
