LOW 138.025 154.000 25 kHz 001 640
MID 154.005 162.000 5.0 kHz 001 1600
HIGH 162.00625 174.000 6.25 kHz 001 1920
Channel to Frequency Calculation
Channel * Channel Step + Min Frequency = Frequency for Channel
Examples:
- Low Band Channel 20
- 20 * 0.025 + 138 = 138.5 MHz
- Mid Band Channel 300
- 300 * 0.005 + 154 = 155.5 MHz
Frequency to Channel Calculation
(Frequency - Minimum Frequency) / Channel Step = Channel for Frequency
Examples:
- Low Band 151.5 MHz
- (151.5 - 138) / 0.025 = Channel 540
- High Band 172.5 MHz
- (172.5 - 162) / 0.00625 = Channel 1680
