"Weak Signal" refers to SSB and CW long distance
communication. Tropo, meteor scatter and moonbounce
contacts are made in this part of the band. 144.2 is the SSB
"calling" frequency, but otherwise this operation is not
"channalized" FM is not prohibited above 144.1, but good
operating practice suggests keeping all FM above 144.3
SSB / WEAK SIGNAL
.3
With the exception of 144.39 and 144.49,
this territory is “unplanned.” FCC rules
prohibit repeaters, including crossband
mobile repeaters

The Crowded Two-Meter Band
WHAT'S ON THIS CHART? If you scan across the two meter band, you may hear a few
conversations on a few repeaters or simplex channels. The rest of the band may seem empty.
But, as this chart shows, the band is crowded indeed! Every channel in the SERA and ARRL
band plans is shown, with the activity closest to Raleigh indicated for that channel.

WHAT'S ON THIS CHART? This three MHz segment of the 440 ham band
is used for repeater outputs. The input frequencies are exactly 5 MHz above
the outputs (from 447 to 450 MHz) and are not shown on the chart. The
repeater jocks will call this high in, low out. Channel spacing is 25 kHz. This
is a very regular, well organized band segment. The only significant unusual
feature is that in some parts of the country, repeater inputs and outputs may be
inverted from this plan, or low in, high out. Several Northeastern states and
some western states use the low in, high out plan, or a mixture with some
repeaters going each direction.
Standard repeaters now extend down into the 441 MHz block (see next page)

UHF Bandplan
This is a "catch-all" part of the band - digital, crossband repeaters, voice
simplex, links, and an expanded space for standard repeaters. SERA revised
the band plan for this area in 2000. Note the many 12.5 kHz channels - they're
unusable with standard narrowband FM radios.
