CB Radio: Skip propagation and the Superbowl on channel 6

Citizens Band (CB) radio has long been a staple of communication for 
enthusiasts, professionals, and hobbyists alike. Originating in the 
United States in the 1940s, CB radio gained widespread popularity in 
the 1970s through the 1990's. Since then it's popularity has 
significantly waned, but in the world of CB radio, you can still hear
camaraderie among the hobbyists who continue to use this free and 
accessible service.

Operating on 40 channels within the 27 MHz, or 11 meter band, the 
users of CB radio broadcast within a range of frequencies designated 
by the Federal Communications Commission (FCC) for personal and 
business use. Channels are spaced at intervals of 10 kHz, starting at
26.965 MHz and ending at 27.405 MHz. Each channel has a generally 
accepted purpose, from general conversation to emergency 
communication, with Channel 9 historically designated for 
emergencies.

The typical range of a CB radio signal is limited to within a few 
miles to tens of miles, depending on terrain and the elevation and 
arrangement of the antenna. Basically the reach of the signal is 
within line of sight of the antenna, however, under certain 
conditions, radio signals can travel much farther than usual in a 
phenomenon known as skip propagation.

Skip propagation is when radio signals reflect off the ionosphere 
allowing CB radio signals to travel well outside the typical line-
of-sight range. In these conditions, signals can travel hundreds or 
even thousands of miles. Sunspot activity, weather patterns, and the 
time of day all affect this phenomenon that seems to come and go 
without much warning. However, monitoring sunspot activity can help 
determine when the best chances of catching skip propagation occur.

During periods of high sunspot activity, or "solar maximums", the 
ionosphere becomes more ionized enhancing the way radio signals 
reflect. This allows CB radio signals to reach across continents 
turning it's normally short range into a global reach. Even with the 
4 watt limitation on transmitting power, signals can literally travel 
across continents.

To boost a signal even more, some CB users will illegally amplify 
their signal to power levels well beyond 4 watts. These amplified 
signals are much stronger and can drown out weaker signals operating 
within the legal limits. Users of amplified CB radios have 
congregated around channel 6, or 27.025 Mhz, and created a language 
and culture all their own. Calling out to each other using nicknames 
called handles they try to reach the farthest with the strongest 
signal.

Tuning into channel 6, nicknamed the "Superbowl channel", you can 
hear these enthusiasts use the typical superbowler lingo like "giving
a wave", "getting down" and "bye, bye, bye" They refer to themselves 
using handles or 3 digit numbers that may coincide with their zip 
code or birth date. The channel 6 regulars have an awful lot to say 
and at the same time aren't saying much at all, just shouting out 
their name and listening for confirmation they were heard.

Some CB users look at these superbowlers as an annoyance, with their 
overpowered signals bleeding into and interfering with signals in 
channels above and below their operating frequency. With 40 otherwise 
unused channels and 3 different modes of operation to choose from, 
though, it seems like an issue that is easily be remedied. After all,
CB radio fosters a sense of community among its users. On Channel 6, 
this community is particularly pronounced, those in opposition can 
form communities on a different channel. There is plenty of frequency 
to go around.

To me, the camaraderie found on Channel 6 reflects the enduring 
appeal of CB radio. Individuals from diverse backgrounds come 
together to share their passion for radio and communication. Whether 
discussing the latest equipment upgrades, swapping stories from the 
road, or simply calling out nonsense in an effort reach distant 
receivers, these interactions contribute to a rich tapestry of 
experiences unique to the CB radio community.

CB radio continues to captivate enthusiasts around the world, 
offering both practical communication and a sense of connection that 
transcends its technical limitations. The phenomena of skip 
propagation and the vibrant community on Channel 6 illustrate the 
enduring allure of CB radio, where each transmission carries not just
information but also a piece of the shared experience that binds its 
users together.
