VK3YNG Sniffer 4 Instruction Manual (for V2.2 hardware)

Frequency Entry

The sniffer can operate at any frequency in the range 120.000-122.995 and 143.000 -

149.995MHz in 5KHz steps. Pressing the "F" button initiates frequency entry. The

display confirms this by displaying "F". The sniffer then expects four digits to be

keyed in to set the desired frequency. If an error occurs while entering frequency, the

letter "E" is briefly displayed and the sniffer then reverts to the previous operation

frequency. The first digit sets both the 1MHz frequency and the band. 0 through 2 sets

the 120MHz band. 3 through 9 set the 140MHz band.

145.300MHz

145.700MHz

144.250MHz

146.500MHz

121.500MHz

146.575MHz

Note: 121.5MHz is used as an international personal, maritime and aeronautical

distress beacon frequency. With an appropriate antenna, the sniffer can be used to

locate ELT and EPIRB emergency beacons.

For the scan function to work correctly, the frequencies stored in channels 5 and 6

should be in the same band. This is not the case for the factory default configuration.

Direct frequency entry is not permitted in reduced functionality mode.
