Radio "Q" Codes
Q Codes for Radio Communication
The "Q" code is a standardized collection of three-letter message encodings, also known as a brevity code, all of which start with the letter "Q". Q codes are commonly used in voice communications as shorthand nouns, verbs, and adjectives making up phrases. Q codes can be used to confer information, or when followed by a "?" used to ask a question.
Initially developed for commercial radio-telegraph communication, these codes were later adopted by other radio services, such as marine, aviation, and amateur radio. The codes are broken down into 3 catagories for use in different radio services:
QAA to QNZ For Aviation use.
QOA to QQZ For the Maritime Services.
QRA to QUZ Used in all radio services.
Q Codes QRA-QUZ - All Radio Services
QHF Going to the Hamfest
QRA Name of your station
QRB Distance from my station
QRD Departing & destination Locations
QRG Exact frequency

TERMS:
YOU ARE REQUIRED TO AGREE TO THESE TERMS IN ORDER TO PURCHASE FROM THIS WEB SITE.
I BELIEVE IN QUALITY BEFORE QUANTITY! (And from the sales I'm receiving, so do you!)
SO IF YOU'RE IMPATIENT, DO NOT ORDER FROM ME!! Let me repeat that, IF YOU'RE IMPATIENT, DO NOT ORDER FROM ME!! I SIMPLY REFUSE TO RUSH MY BUILDS.
Each radio goes through 24 hours minimum of burn-in testing when it's finished. IT WILL BE RIGHT WHEN IT LEAVES MY SHOP!
Normal turn around times;
"Major Custom radio's" 280 to 320 business days.
"Custom/Modified radio's" 45 to 60 business days depending on model.
"Stock/No option radios" are usually 1 to 2 weeks.
Depending on the difficulty of your build or the builds in front of it, this time could be longer.
"Major Custom" in this case means that you have added an option that requires a significant modification(s) to the stock radio that takes more than 3 hours to install. Such as the SP-1a, AD-203, upgrading amp deck, LesComm RCI Noise Filter, etc. are considered Major Custom builds.
"Custom/Modified" examples include LesComm Enhancements, Basic Clarifier mod, Amp Switch, Hi Cut Filter, etc. just to name a few. However if you add a lot of these small upgrades it could move your order to the "Major Custom" category.
"Stock/No option" means just that. These receive only a general tune up.
***Does not apply to Scanners. Scanners ship within 48 hours of purchase.
Customers are taking advantage of the MANY custom options we offer . Depending on the difficulty of your build OR THE BUILDS IN FRONT OF IT, this time could be longer!
There are NO REFUNDS for custom radio, amplifier or power supply orders. NO EXCEPTIONS! NO EXCEPTIONS!
SO BE SURE BEFORE YOU ORDER!
20% restocking fee on "as new, non-customized" radio returns. Radios are built AFTER they are ordered in the order of "payment" received.
AGAIN, THERE ARE NO REFUNDS OR RETURNS ON CUSTOM RADIO, AMPLIFIER OR POWER SUPPLY ORDERS, AND KITS, NO EXCEPTIONS. So be sure BEFORE you order!
This is how it works folks. When you place an order for one of our custom radios we immediately (that day) order the necessary parts needed to build that radio including the donor radio, and set them aside for your build. So we have already invested your money in your order. We do this to prevent coming up short of the parts needed because it was discontinued or changed. (Which happens a lot!) I know this is a long time folks. But I'm only one person. I will work as fast as I can, without compromising quality, to get your order out. So as it says above, if you are an impatient person, do not order from me.
YOU ARE REQUIRED TO AGREE TO THESE TERMS IN ORDER TO PURCHASE FROM THIS WEB SITE.
We very much appreciate your business. And to all of my many, many repeat customers a very special thank you. Tells me I'm doing something right! 73 Everybody!
