People on certain frequencies and bands use a type of communication that may seem unintelligable. There are 10-codes that first responders use, as does those on the CB (Citizens Band) channels. Q-Codes are used by HAM and sideband CB operators. Some of the more common (but not all) 10 and Q codes are below. You can always search the internet for more specific codes. Also listed are names for each letter of the alphabet and the morse code key.
|10-3||Stop Transmitting or Change Channels|
|10-4||OK, Message Received, understood, yes/affirmative|
|10-5||Relay this to...|
|10-7||Out of service / Off Air|
|10-8||In service / On Air|
|10-9||Please repeat your message|
|10-10||Depending on context, it could mean negative, out of service, transmission completed|
|10-11||Talking too fast|
|10-12||Standby, visitors present, disregard, at scene|
|10-13||Asking for weather/road conditions|
|10-14||Suspiscious person/prowler, convoy or escort|
|10-20||What's your location/My location is...|
|10-21||Call by phone|
|10-25||Can you contact...|
|10-26||Disregard last transmission|
|10-27||Moving to channel...|
|10-28||Identify your station|
|10-29||Time is up for contact (NOTE: FCC CB Radio rules prohibit talking continuously or in conversation for more than 5 minutes at a time. After 5 minutes one must wait 1 minute (60 seconds) before starting a new transmission).|
|10-30||Does not conform to FCC Rules|
|10-32||I will give you a radio check (ie. they will let you know how strong your signal is coming in on their receiver).|
|10-33||Emergency at this station (where you are located)|
|10-36||The correct time is...|
|10-73||Speed trap at...|
|10-90||Talk closer to the mic|
|10-100||Need a pee break :P|
|CQ||Calling for anyone listening to respond. Usually an invite to talk with whoever is out there listening.|
|DX||Used with CQ to run skip, that is asking to talk with someone from out of the area or out of the country. As in CQ DX|
|QRT||Shut down for the night, clear|
|QSX||Standing by on the side|
|QSY||Move to another frequency (Channel)|
For more codes (including those used by police and other responders), and other CB lingo, please see:
These are used to clarify spelling a word, name, or whatever. Often used in military, police, first responders, and also sometimes in general phone and non-face-to-face verbal communication, especially when reception is particularly not very clear. You hear this quite a lot on CB and HAM radio. HAM radio operators use these letter names to clarify their licenced call sign.

Morse code is the use of long and short beeps for each letter of the English
alphabet. This is used in the military, marine and HAM radio mostly. At one time
HAM radio operators had to be able to read and send Morse Code at a certain
rate in order to pass their tests to get a license to transmit. This is no
longer a requirement. CB Radio users never did have to learn morse code, but in
the 70s some toy radios (and some more serious versions) had a Morse Code key
generator and the Morse Code lookup printed on the radio (or as an extra insert
with the radio documentation). Everyone is probably familiar with the
dit-dit-dit-dah-dah-dah-dit-dit-dit pattern (SOS) that was made famous by the
movie Titanic. Though this was not where it originated. For more
interesting information on this topic including where the SOS actually originated,
look at this Snopes Article.
The dots are often referred to "dit" (short beep) and dashes often referred to as "dah" (long beep).

Another way to learn morse code is to learn the Morse Code Tree:
Here is a video to explain how to use the tree:
Here is someone who is very good at the old-style manual keying of Morse Code!
