1x1 call sign station identification procedures and other rules

From The WB7TJD Wiki

This page has been reworked, and a correction made in the "ONE TRANSMITTER PER BAND" section.  Since we no longer use the W7W call sign, I have replaced it with a fictitious K7X.

This page is supposed to be a general guide for any special event station operation using 1x1 call signs.


Station Identification While Operating A Special Event Station

If starting out on a new frequency, please ask "Is this frequency in use?" and listen.  Once a clear frequency has been established, proceed with your transmissions.

We will use call signs not issued in the amateur service, but that look like ham calls in our examples.  This way, we avoid using an actual call sign issued to a licensed amateur.

The control operator's call sign is W7XYZ.  Substitute your own call sign in its place.

The Special Event call sign is K7X.  Calls ending in X are not issued by the 1x1 call sign registry.  Substitute the actual 1x1 call for K7X.

The special event is an unlikely "First Manned Mission to Jupiter."  Replace that with your special event info.

At the beginning of operation

Upon determining a clear frequency as close to the published frequency as possible for the event, one should start by calling CQ:


Hello CQ CQ CQ, this is K7XYZ running the "Manned Mission to Jupiter" Special Event Station K7X, Kilo 7 X-Ray, K7X, celebrating the "Manned Mission to Jupiter" calling CQ and listening.

Identify once every ten minutes and once at the end with K7X, identify once per hour and at end of your shift with K7XYZ, making appropriate substitutions.

It would be a good idea if when changing frequencies, you sign K7XYZ as K7X on the old frequency and again on the new.


Start of operation, use of new frequency:


Once at end of shift, end of use of a frequency, or once per hour:


On PSK31 or other digital modes, of course a script can be run to print out info about the special event in addition to these bare-bones minimum ID requirements. If conditions permit, more info can be included on CW as well.

Call Signs Containing Letter Z

English-speaking people outside the United States commonly use "Zed" for the name of the letter Z.  One less point of confusion is created with universal amateur use of "Zed" to distinguish between C, T, P, V and D versus Z.

New Zealand calls beginning with ZL are always called "Zed Ell."

Use of Phonetics Helps

The use of phonetics is very helpful, as well.  The standard phonetic alphabet can be seen here:  Standard Phonetic Alphabet


Brian Betz, W7JET brought up the "One Transmitter Per Band" issue with ARRL/VEC band was advised that we may indeed operate one transmitter PER MODE per band.

This means that two transmitters may sign as K7X, to use our fictitious example call, on the same band, one running a voice mode and one running a digital mode.  Thanks Brian for that tip, for this page was previously limiting the number of transmitters per band to one, regardless of mode.

I would have to investigate further to determine if we can run say PSK31, which is F1B, and CW, which is A1A at the same time on the same band.  As I get the chance I will either have to ask Brian to investigate further or ask the ARRL myself.

When I did a Google search for a clarification on the issue of 1x1 station rules, this page was offered up third on the list, with none of the other leading contenders addressing my question at all.


That is what this event is all about.

This event was intended to give us a group outing, and a chance to get together.  Let's introduce the newest licensees to the world of HF, but beware, there are some bad apples out there who like to abuse the Privilege to operate on shortwave frequencies in the amateur radio service.

Best bet if you hear some foulmouthed so-and-so is to just bite your lip and spin the dial.

Calling CQ

You can Taylor your CQ calls to suit, but the basic idea is, we are not on a channelized FM frequency like we are on two meters.  Therefore, it is important to say "CQ" three to five time and repeat the 1x1 call sign both as letters and phonetics:  This is K7X, Kilo 7 X-Ray."

  • CQ CQ CQ, calling CQ, hello CQ.  This is special events station K7X, Kilo 7 X-Ray, calling CQ.  K7X, Kilo 7 X-Ray calling CQ and Listening."
  • "Hello CQ CQ CQ CQ CQ, calling CQ. This is K7X, Kilo 7 X-Ray, the first ever Manned Mission to Jupiter, calling CQ. Special Event Station Kilo 7 X-Ray by for a call."
  • "Manned Mission to Jupiter Special Event station K7X calling CQ, hello CQ CQ CQ.  NASA's boldest move ever, Kilo 7 X-Ray, K7X.  Whiskey 7 Whiskey, W7W, calling CQ and standing by."

The important thing is to keep the frequency busy.  Stand by for a call, and if you don't hear anything in three to four seconds' time, call again. Leave a break for four or five seconds and call again.

If you put out a short call like you might do on 2 meters and stand by for 25 seconds, you might find someone else using the frequency, so once you pick one, keep it rolling.

Using the microphone

You want to speak across the face of the microphone at fairly close range, and adjust the mic gain downwards versus speaking from half a foot away from the mic and raising the gain.  Speak in a level tone of voice (not a monotone, but a constant level).  This helps you keep the power density of your signal at near the maximum capability of the radio, and your signal is loud and clear.  Watch the ALC meter to keep the meter within the allowable range.  IF you have a WIDE dyNAMic RANGE from a whisper to a loud intensity, you have a devil of a time keeping a reasonable amount of power coming out to the antenna, maybe a peak of 100 watts and maybe an average of maybe 10 watts, instead of an average of 80 watts.

This all takes practice.  Back when I was first on the voice modes I was running AM on 160, and I learned to speak in a very constant level voice, and I accentuated the S sounds of words.  All in an effort to boost my intelligibility on a noisy band.

When I met one of the guys I was talking with, he noted that I Sounded very criSp with lotS of SSS SoundS in my voiSe in person!  I guess I was all of 19 or 20.

Most important rule in using a microphone:  Don't be shy!
