The thing with channel 9

Category: /

jackson ii ch9Since the mid-1970s, CB radio in Europe was gradually allowed by all countries, at that time with lower transmission power and primarily AM mode. Even then, channel 9 (if alternative channel 19 was disturbed) was used as a call and emergency channel, and not without reason. If you look at (see picture) two-way radios, they mostly have a switch that allows the quick change to channel 9.

alan 42ds ch9Back then, it really made sense, because every second car had an antenna, there were no cell phones yet, and in an emergency, the nearest phone booth was often miles away on a highway or country road. With the introduction of the first C and D networks, later GSM car phones, this changed step by step.

Nevertheless, channel 9 on CB radio still has a special position, even if nobody would come up with the idea of calling an emergency doctor via CB radio - which is also logical and a good thing. But its authorization at that time as a call - info - trucker and help channel is undoubtedly still valuable and helps many on the streets.

But what rules apply to CB radio and channel 9 ?

The general basic rules apply that apply to CB radio, but also to amateur radio and in all channels.

  • Channel 9 should always be kept as free as possible, it is not bad if it is often quiet and quiet

Procedure for calling a station

  • One calls e.g. with the following wording: teddy bear QRZ Schlumpfi or teddy bear for Schlumpfi
  • If the called station is QRV (= ready to send / receive), the station answers with a suggestion which channel you want to use, that is e.g. Schmlumpfi is QRV and QSY on channel 5 or simply Schmlumpfi is there, go to channel 5

This prevents channel 9 from being seized, too long radio communications or conversations on the call / emergency (= call and help channel)

Procedure to get information

  • One calls e.g. with the following wording: Teddy bear on A8 towards Munich, need info
  • A station that hears this can now answer and immediately put the questioner on another channel so that channel 9 is free again. that is e.g. Schlumpfi has information and goes to channel 5

This prevents channel 9 from being seized, too long radio communications or conversations on the call / emergency (= call and help channel).

Is this radio discipline necessary?

Out of courtesy to everyone else. If I am not in a call, I usually have channel 9 switched on and everyone can find and call me there. But now many are also in a conversation. These radio operators can (and do) use the so-called DUAL WATCH (= two-channel monitoring). That means they are talking e.g. on channel 12, but have set DW (= dual watch, two-channel monitoring) on channel 9. So if you get a call, you can answer (or not) and a smooth process and quick and good information can be passed on quickly.

Generally applies in any caseCourtesy, respect and adherence to radio discipline

  • No interruption and disruption of ongoing calls
  • Compliance with the pauses between the radio messages
  • Do not interrupt ongoing conversations or only interrupt them with a 'break break' if you want to register and have a say in the topic, or if you have important additional information to share.
  • Why break break twice? the second break will definitely get through. QRX or XXX have completely different meanings, even if this is common in Germany.
  • The XXX is (Morse code --..-- --..-- --..--) an emergency call signal on amateur radio.
In addition, some rules are important to enable regulated, fluid and problem-free radio communication
  • The more participants the more important are short, crisp and informative radio messages without long decorations
  • Breakers, i.e. when someone with two 'break breaks' switches into radio communication, always have priority on channel 9 because it is usually about important information or requests.
  • If you want to have a longer conversation with other participants on a topic or for other reasons, you suggest another channel, conduct your conversation there in peace and then return to the call info trucker and help channel 9
  • Since Midland CBtalk now also has DUALWATCH (two-channel monitoring). Is there also a great opportunity to talk on a channel and still not miss any important information, a call or a call for help (channel 09 set to dualwatch).
  • Small talk is possible as long as the sayings are as short as possible and above all the breaks in between remain. Loose conversations of this kind are immediately interrupted if, for example, accident or traffic jam reports or other important information are reported. Normally, the station concerned breaks into the channel with two 'break breaks' in order to be able to communicate the information.
  • In addition to the previous CB radio devices with HF radio, device and antenna, there is now also the CBtalk APP from Midland, which can be considered a valuable tool for professional drivers. Of course, channel 09 (highlighted in yellow) (depending on the country, e.g. DEU09 or AUT09) is also available here.
What to avoid
  • The 'break in' so interrupting to join a conversation should not be misused. For example, if there is a conversation, the exchange of traffic information, etc., it is not appropriate to set a 'break break' just to say 'good morning'. Then you have to wait until there is a longer break and simply register with a 'Station XY is QRV' as ready to receive. (Abbreviations and so-called Q codes can be found here)
  • Above all, it is rude to interrupt and disrupt ongoing radio traffic with interruptions. Listening, waiting to see what it is about and if you want to have a say in a 'break break' is the more correct and above all polite way.
  • If there are larger radio rounds on one frequency / one channel, one of the radio operators is usually active as a moderator and tries to call up the participating stations as equally as possible.
  • What you should not do under any circumstances is to pass on the microphone (request to speak) to another station if a radio operator acts as a moderator. Otherwise the radio discipline is gone again and everything is mixed up. Everyone is frustrated again and nobody is helped.
  • Simply to enter conversations here and change the subject, for example, or if you were asked to speak to another station to continue speaking and thus to override the moderator is not only very rude, but a 'no go'
What else to say

As in normal everyday life and in dealing with fellow human beings, you should have a respectful and polite conversation with everyone, especially on the radio. If there are really troublemakers and contemporaries on the channel, the best defense is to change the channel, ignore these troublemakers or simply be silent for a while - then such incidents usually take care of themselves after a short time.


Lead by example, be a role model - others will follow and you will meet new friends from all over the world and the hobby radio will be an asset!
