Let's program the hunting channel now by letting the LHS button go first, then the RHS button. The sniffer emitts a continueous high tone to indicate it is ready for programming. Now you program in the 10 channel bits. The LHS button is used for binary "0" and the RHS button for a binary "1".
The first set of 5 bits represents the number of 125kHz (1/8 MHz) steps from 144.000 MHz.
ie: bit: 1st 2nd 3rd 4th 5th
step: 2MHz 1MHz 500kHz 250kHz 125kHz
The second set of 5 bits represents any furthur offset in 5kHz steps to obtain the required frequency.
ie: bit: 6th 7th 8th 9th 10th
step: 80kHz 40kHz 20kHz 10kHz 5kHz
eg. 146.750MHz = 144.000MHz + 2MHz + 500kHz + 250kHz = 10110,00000
145.550MHz = 144.000MHz + 2MHz + 500kHz + 50kHz = 01100,01010
The same entry scheme applies to the liason channel when you let the RHS button go first. When you finish programming the sniffer reverts to normal operation.
