JA> Repeaters for CB! WOW!
Yes, we've had them since the end of the 1970s! :) In the cities they have
tended to be cesspits for every carrier dropper and pissing contents, but away
from the major cities, repeaters are community hangouts and resources, commonly
called upon during emergencies.
Repeater specs are:
Output frequency 476.425 - 476.6125 MHz in 12.5 kHz steps (UHF channels 1-8 and
41-48).
Input frequency - 477.175 - 477.3625 MHz (UHF channels 31-38 and 71-78, 750 kHz
offset).
The reason for the odd channel numbering is the band plan. Channels 1 - 40 are
from 476.425 MHz to 477.400 MHz in 25 kHz steps. Channels 41-80 were added
when the channel spacing was changed to 12.5 kHz in 2011. They start at 12.5
kHz above channel 1 at 476.4375 and go up in 25 kHz increments (i.e. between
the original 40 channels) up to 477.4125 kHz. So the repeater segment is
actually contiguous, despite the spacing in the numbering.
