Part 15 band - ISM band and 33cm amateur radio band shared.
These radios operate with 50 kHz channel spacing and 8-level FSK digital FHSS 902-928 MHz band (channels start at 902.525 MHz and continue to 927.475 MHz, 525 kHz from band edges for a total of 500 available channels at 50 kHz channel spacing), in compliance with Part 15 of the FCC rules - specifically 47 CFR 15.247. The DTR 900 MHz digital business radios offer performance comparable with UHF walkie-talkies as far as in-building coverage goes.
Hopsets
10 frequency sets of 50 frequencies each. Spacing within each hopset is 500 kHz. Since each hopset is 50 kHz offset from the previous hopset, the overall channel spacing is 50 kHz.
- Hopset 1 902.525 MHz, 903.025 MHz, 903.525 MHz, 926.525 MHz, 927.025 MHz
- Hopset 2 902.575…927.075 MHz
- Hopset 3 902.625…927.125 MHz
- Hopset 4 902.675…927.175 MHz
- Hopset 5 902.725…927.225 MHz
- Hopset 6 902.775…927.275 MHz
- Hopset 7 902.825…927.325 MHz
- Hopset 8 902.875…927.375 MHz
- Hopset 9 902.925….927.425 MHz
- Hopset 10 902.975, 926.975 MHz, 927.475 MHz
