Change of Address

Have you moved since you got your amateur radio license?  This is a common concern for renters or apartment-dwelling hams and revocation or suspension of your license is the ultimate consequence of failing to notify the FCC.

If you have relocated your QTH from one place to another, or if you have otherwise changed your mailing address, you are obliged to update your postal address with the FCC in the United States.  The FCC needs to know where to reach you by mail for either operator or station license questions or issues.

It’s also common courtesy to other hams who want to send QSL cards or just to know where you are located based on your call sign.

US Code of Federal Regulations 47 C.F.R Section 97.21 requires you to file timely for an update of the license as necessary to show your correct mailing address, name, club name, license trustee or custodian name. Revocation of your station license or suspension of your operator license may result when correspondence from the FCC is returned as undeliverable because you failed to provide the correct mailing address.

In the US you can update your address online (filing electronically) at Continue reading

Q-Codes

Back in the ham-speak topic we noted that ham radio vocabulary includes plenty of jargon and lingo.  As mentioned there, it is best to not use too much ham-speak on the air, since plain language is preferred for voice modes (phone) but in reality you still hear many code words and abbreviations being used.

You will run across many terms on the air as well as in books and magazines and perhaps in email that are cryptic to the new or prospective ham.  To help you with this we will present the topic of Q-codes here.

The Q code (or Q-code) is a standardized collection of three-letter codes, all of which start with the letter Q, where each code has a particular meaning. These brevity codes were originally developed for commercial radiotelegraph use but were quickly  adopted by amateur radio operators.  Although Q codes were created when radio used Morse code exclusively, they continued to be employed after the introduction of voice transmissions. Some history on Q-codes can be found here and here and here.

Listed below are ten Q-codes the average ham is most likely to hear (in the author’s opinion), along with their meaning and common usage:

  • QRM- Man-made interference, interference from other stations.
  • QRN- Natural interference, typically static or crashing from thunderstorms.
  • QRP- Low power transmit, generally 5W or less.
  • QRT- Quitting; stopping transmission or shutting down station.
  • QRZ- Who is calling me?
  • QSB- Fading signal.
  • QSL- I acknowledge receipt; also confirmation of contact.
  • QSO- Conversation, radio contact and exchange.
  • QSY- Change frequency.
  • QTH- Location.

You should be familiar with at least these and perhaps some others as well.  Comprehensive lists of Q-codes can be found here and here and here and here.t21b10

The main point here is not for you to learn Q-codes to use them, but to understand them when you inevitably hear them.

That’s all for now so 73 and I’ll be QRT.
