RADIO SIDEBAND Q CODES
11 Meter CB
SSB Q codes
The " Q-Codes
" were initially a standard collection of three letters all starting
with Q used for commercial radio telegraph services. Like any
other code, they were soon adapted by other services. The codes
in the range QAA-QNZ are reserved for aeronautical use; QOA-QOZ
for maritime use, and QRA-QUZ for all services. Sometimes you
will hear a policeman on COPS say "QSL", meaning 10-4. OK. These
codes are are widely used in CW operation in Amateur Radio. They
are not so popular in Ham Radio voice modes. Ham operators on
voice seem to have limited themselves to the use of just a few
on these Q-Codes.
You will also
hear 11meter cb radio operators using these codes on SSB (sideband).
Cb Radio "Sidebanders" often use the efficiency of SSB to talk
greater distances. Cb Sideband operators are usually folks looking
to use cb as a more professional means of communication as compared
to channel 19 AM.
Mistake on Cb Radio: There is one particular mistake in ssb cb
radio q code operations. It's misuse is so bad it has raged on
as an epidemic for years. It is "QRT". QRT means someone is shutting
their radio off or leaving the radio. Someone going QRT won't
be back till later. Usually alot later like tomarro. The usual
designation of QRT is "stop transmitting". The problem is, some
cb sidebanders have confused this and made it literal. You will
often hear a rookie SSB cber say "This is blah blah and we are
QRT and standing by". This is wrong. QRT means you are "shuttin
er down". Sometimes you will hear an old cber mock those that
make this mistake by saying "what are you going to shut your radio
off and stand beside it"?
