351 MHz UHF Digital Personal Radio Service - Japan. Registered station “standard waves” (channels, frequencies). Sometimes translated as simple radio service or simple UHF radio service.
351.025 MHz - 351.6375 MHz One of numerous UHF band personal radio services available in Japan.
Similar in function to FRS in the United States, Canada, etc.
Uses the low-UHF 300 MHz band like the 325 MHz Short Range Radio Service in the Philippines, the 350 MHz Short Range Radio in India and the 300 MHz - 344 MHz "River Cruise" radio service in Russia and the former Soviet Union. This is likely why the 350 MHz band is included in some multi-band transceivers coming out of China in the mid-2020s.
82 channels at 6.25 kHz spacing, plus 15 receive only channels for a total of 97 channels. Transceivers are advertised as 97CH transceivers, 82CH transceivers and variants of those two. 351.2000 MHz is often shown as "Channel 1" or "Channel 001".
351.03125 MHz - 351.10000 MHz transmit and receive 351.10625 MHz - 351.19375 MHz receive only “sky channel” 351.20000 MHz - 351.63125 MHz transmit and receive
See also: 27 MHz CB in Japan as well as double side band DSB (AM) and SSB 27 MHz fishery radio services in Japan and the Specified Low Power Radio 420 MHz/421 MHz/422 MHz band service.
5 watt transmit power limit, digital voice using ARIB type vocoder standard 3R3T 4-level FSK. F1C F1D F1E F1F emissions designators:
- 6K00F1C
- 6K00F1D
- 6K00F1E
- 6K00F1F
351.025 MHz - 351.6375 MHz. Like other personal radio services in Japan, all radios must be registered and transmit a unique radio ID number via a built-in ROM. Automatic digital callsign identification. 6.25 kHz channels, narrow band, similar to DPMR446.
Selective calling (user to user calling, group calling, etc. using UC user codes 000 to 511 (512 unique user codes). Encryption capability included with 32,767 unique “codes” encryption keys. Handheld and vehicle mounted (mobile in-vehicle) radios available on the Japanese market.
