Russian UHF short range handheld radio service. Probably authorized or at least used in other former Soviet republics (CIS, etc.)
Portable UHF service, 300 MHz band. NFM
- 300 MHz - 300.525 MHz
- 301.125 MHz - 305.825 MHz
- 307.025 MHz - 308 MHz
- 336 MHz - 336.525 MHz
- 337.125 MHz - 341.825 MHz
- 343.025 MHz - 344 MHz
Output power 5w, full CTCSS and DCS selective calling, 5 kHz, 6.25 kHz, 10 kHz, 12.5 kHz, 25 kHz spacing. Specifications are from the "river radio" model Cruise-7, which appears to be a modified Yaesu handheld.
- 300.000 MHz - 300.525 MHz
- 301.125 MHz - 305.825 MHz
- 307.025 MHz - 308.000 MHz
- 336.000 MHz - 336.525 MHz
- 337.125 MHz - 341.825 MHz
- 343.025 MHz - 344.000 MHz
Possible pairing with 36 MHz offset (split)
- 300.000 MHz - 300.525 MHz with 336.000 MHz - 336.525 MHz
- 301.125 MHz - 305.825 MHz with 337.125 MHz - 341.825 MHz
- 307.025 MHz - 308.000 MHz with 343.025 MHz - 344.000 MHz
Total spectrum is 14.350 MHz. At 12.5 kHz channel spacing, that is 1148 channels. If the system is half-duplex or split, then 574 channels. At 25 kHz spacing the total available channels drops down to 574.
Additional research regarding this spectrum indicates that it may be allocated a shared service status with NB-IoT narrowband Internet of things.
Frequency allocation table and notes from Moldova indicate that a very similar frequency band is "shared", but information is sparse.
RN024 Within frequency bands 299.6 – 300.0 MHz, 300.525 – 301.125 MHz, 305.825 –307.0 MHz, 308.0 – 308.4 MHz, 335.6 – 336.0 MHz, 336.525 – 337.125 MHz, 341.825 –343.0 MHz and 344.0 – 344.4 MHz separate frequencies can be used by non-governmental users subject to agreement with competent state security entities.
