Each signal can be a question or an answer, as shown in the Meaning column. Here are the Q signals most commonly used in day-to-day operation. Hams use three-letter Q signals on every mode and even in face-to-face conversation.

As a Technician licensee, you have free access to all amateur frequencies above 50 MHz, but what about on the shortwave high-frequency (HF) bands? This chart helps you follow the rules. When you’re getting started, remembering where you’re allowed to operate is important. Thank you, too, for your support of these sites.Technician Class Frequency Privileges in Ham Radio Additionally, we always try to include links to other retail options if they are available, as we support and freely advertise independent ham radio retailers.

Many of you have suggested in the past that the SWLing Post join an affiliate links program. If you’ve roamed the bands for RTTY signals you’ll find that most are encrypted with a few exceptions, one of which is WLO which is transmitting continuously. These are most commonly used by amateur radio ops too. The RTTY ( Radio Tele TYpe) parameters used by WLO transmissions are 45.45 bauds, 170Hz shift. Those of you who are neophytes to RTTY or just want to dabble then this is the place to be to try your hand at an old and venerable digital mode. Here on the East Coast it is received with regularity due to it’s strong signal. Non-voice high seas weather broadcasts and safety messages to mariners can be found by spinning your VFO dial to 8.472 MHz USB courtesy of WLO from Mobile, AL, which provides these transmissions continuously.
