Beacons
Beacon Channels are allocated on a state/frequency basis - eg 144.410-144.419
is allocated to VK1, 144.420-144.429 VK2 etc. The beacons are channeled
in 2KHz increments.
Narrowband & Weak Signal Segment
This segment is reserved for modes such as CW, digital modes and SSB with bandwidths up to 4 kHz. Weak
signal operation has absolute priority. Calling frequencies should be used only to make initial contact and
then vacated as soon as possible. Please avoid any terrestrial operation within the EME segment.
The following spot frequencies are recommended for digital DX operation using SSB-based modes:
144.220 / .320 Weak signal modes with bandwidths below 100 Hz, e.g. PSK and slow CW
144.225 / .325 Weak signal modes with bandwidths up to 750 Hz, e.g. MFSK, JT65 and similar
144.230 / .330 High speed meteor scatter modes with bandwidths up to 3 kHz, e.g. FSK441
Note that the segment 144.110 � 144.160 MHz is also used for international digital mode EME operation.
The band 144.3 - 144.5 MHz is not an IARU recognised satellite band, however some frequencies in this
segment may be used at times for space communications
Exclusive Simplex Channels
The following simplex channels are available for general use on the
2m band.
145.325 146.425 147.425
145.350 146.450 147.450
145.375 146.475 147.475
145.400 146.500 147.500
145.425 146.525 147.525
145.450 146.550
145.475 146.575
145.500
145.525
Be aware that 146.500 and 147.500 are national call channels. Contact should be established on
these channels and then the operators should QSY. Where a repeater pair is not in use in the
local area, it too is then available for simplex working, but users should be aware of DX conditions
that may trigger distant repeaters.
Historical information: Packet Channels
The following channels have been allocated to packet activity requiring
a bandwidth less than 16KHz.
144.700 147.550 145.075 (>1200bps Primary Use)
144.725 147.575 145.100 (>1200bps Primary Use)
144.750 147.600 145.125 (>1200bps Primary Use)
144.775 145.150 (>1200bps Primary Use)
144.800 144.975 145.175 (>1200bps Primary Use)
144.825 145.000
144.850 145.025 145.200 WICEN Packet Channel
144.875 145.050
144.900
144.925
Repeater Channels
Repeater Channel spacing is 25 kHz for repeaters occupying 16 kHz bandwidth, or 12.5 kHz wherever possible for
repeaters occupying 10.1 kHz bandwidth. Transmit - receive offset is 600 kHz, but 1.6 MHz offset may be
used in the 147 MHz segment.
The alternative repeater input segment 145.400-145.800 (-1.6 MHz offset) and the repeater outputs in the
144.925-145.050 segment will only be allocated when no standard 600 kHz offset channels above 146 MHz
are available.
