Channel and Hop Tables (900 MHz ISM Band Only)
The number of ISM channels varies with modulation
1
. The following sections provide channel
frequencies, spacing, bandwidth and minimum channel requirements for the available FHSS and DTS
ISM modulations.
The radio generates hop tables automatically based upon the modulation and frequency range in use.
The following is true for the complete 902-928 MHz ISM Band;
– 57 MSK 171 channels with 76.45 kHz bandwidth 1.
– 114 MSK 165 channels with 154.29 kHz bandwidth.
– 153 MSK 123 channels with 207.11 kHz bandwidth.
– 229 MSK 82 channels with 309.97 kHz bandwidth.
– 663 2FSK 26 channels with 900 kHz bandwidth.
– 884 BPSK 20 channels with 1.2 MHz bandwidth.
– 1768 QPSK 20 channels with 1.2 MHz bandwidth.
– 2651 8PSK 20 channels with 1.2 MHz bandwidth.
– 3535 16QAM 1 20 channels with 1.2 MHz bandwidth.
– 3535 16PSK 1 20 channels with 1.2 MHz bandwidth.
– 4419 32QAM 1 20 channels with 1.2 MHz bandwidth. provides

57 MSK uses the lower ISM band (902–915 MHz) even when Band Stop is set to 928 MHz.
Additionally, using the Exclude MHz settings to exclude 902 – 915 MHz has no effect and the Radio will
continue to use the lower half of the ISM band.
To force the radio to use the upper ISM Band (915 – 928 MHz), set Band Start to 915 MHz and Band Stop
to 928 MHz.
The radio will then use the upper half of the ISM Band maintaining 166 channels with 76.45 kHz channel
bandwidth.
