Across all of North America, the National Simplex Frequency (also referred to as the calling frequency) is 146.52 MHz. In areas that use 15-kHz channels, the adjacent channels are 146.535, 146.550, 146.565 MHz, etc.
What are US calling frequencies used for?
A national calling frequency in the USA is a radio frequency that is widely accepted and understood to be a place to start communicating with other hams. This frequency is established for each RF band under the voluntary US band plan and is not regulated by the FCC.
What is the 70cm calling frequency?
70 Centimeters (420-450 MHz) 420.00-426.00 ATV repeater or simplex with 421.25 MHz video carrier control links and experimental 432.07-432.10 Weak-signal CW 432.10 70-cm calling frequency 432.10-432.30 Mixed-mode and weak-signal work 432.30-432.40 Propagation beacons.
What is the most popular ham radio frequency?
20 meters – 14.0–14.35 MHz – Considered the most popular DX band; usually most popular during daytime. QRP operators recognize 14.060 MHz as their primary calling frequency in that band. Users of the PSK31 data mode tend to congregate around 14.070 MHz. Analog SSTV activity centers on 14.230 MHz.
What is the 220 MHz calling frequency?
The 1.25-meter, 220 MHz or 222 MHz band is a portion of the VHF radio spectrum internationally allocated for amateur radio use on a primary basis in ITU Region 2, and it comprises frequencies from 220 MHz to 225 MHz.
What is CW and SSB?
SSB is a mode. AM is a mode. FM is a mode. CW (Continuous Waveform aka Morse Code) is a mode. RTTY (radio teletype) is a mode.
What is the 6 meter calling frequency?
Six Meters (50-54 MHz) is known as “The Magic Band” to many of its fans, but the best description I ever heard came from a ham I worked during a frantic summer Sporadic-E opening: “This is a great band if you like having Mother Nature pull your chain.”.
What is the 10 meter calling frequency?
The 10-meter band is a portion of the shortwave radio spectrum internationally allocated to amateur radio and amateur satellite use on a primary basis. The band consists of frequencies stretching from 28.000 to 29.700 MHz.
What is the 2m simplex calling frequency?

What is national 2m calling frequency?
Across all of North America, the National Simplex Frequency (also referred to as the calling frequency) is 146.52 MHz.What Frequency Do I Use on 2 meters? 144.000-144.100 CW (Continuous Wave, Morse Code) 146.400-146.595 FM Simplex (National Simplex Frequency =146.52 MHz) 146.610-147.390 FM Repeater Outputs.
What frequencies can I use without a ham license?
The Family Radio Server (FRS) authorizes 22 channels in the 462 MHz and 467 MHz range, and it is available without a license. This device can operate outside those frequencies. Using these outside that frequency in the US could land you with fines, loss of device, or worse.
What frequencies can a technician talk on?
Technician Class Frequency Privileges in Ham Radio Band Frequencies (In MHz) Modes You Can Use 80 meters 3.525 – 3.600 CW 40 meters 7.025 – 7.125 CW 15 meters 21.025 – 21.200 CW 10 meters 28.000 – 28.300 28.300 – 28.500 CW, RTTY/data, 200 watts PEP maximum power CW, phone, 200 watts PEP maximum power.
Where are my local ham frequencies?
The best way to find local frequencies is to download the app RepeaterBook. It will find your location and instantly tell you the local repeaters around your area. You’ll then program those into your radio.
What is the 40 meter calling frequency?
160 METERS 40 METERS 7.000 – 7.010 CW DX & DXpedition Window 7.005 DXpeditions CW are frequently here 7.035~7.045 SSTV Operating Frequency — IARU Region 1.
What frequency is 40m?
The 40-meter or 7-MHz band is an amateur radio frequency band, spanning 7.000-7.300 MHz in ITU Region 2, and 7.000-7.200 MHz in Regions 1 & 3. It is allocated to radio amateurs worldwide on a primary basis; however, only 7.000-7.100 MHz is exclusively allocated to amateur radio worldwide.
Why is it called the 11 meter band?
In 1948, the original CB radios were designed for operation on the 460–470 MHz UHF band. Some hobbyists continue to use the designation “11 meters” to refer to the Citizens Band and adjoining frequencies.
What is CW band?
A continuous wave or continuous waveform (CW) is an electromagnetic wave of constant amplitude and frequency, typically a sine wave, that for mathematical analysis is considered to be of infinite duration.
What is CW on a CB radio?
CW stands for “continuous wave” transmission. Continuous Wave (CW) transmissions were a vast improvement in both efficiency and tone. Today, Hams proudly refer to their communication through Morse Code as CW.
What is RTTY on ham radio?
RTTY (Radio TeleTYpe) is a method of using tones to send digital messages between radios in amateur HF bands (and other services). While it has been around for many years, these days it usually involves using a computer and modulation/demodulation software to send/receive messages.
Is 6m band good?
The 6-meter band is the lowest portion of the very high frequency (VHF) radio spectrum internationally allocated to amateur radio use. During the last sunspot peak of 2005, worldwide 6 meter propagation occurred making 6 meter communications as good as or in some instances and locations, better than HF frequencies.
Is the 2 meter band AM or FM?
While the 2 meter band is best known as a local band using the FM mode, there are many opportunities for long distance (DX) communications using other modes.
What band is 45 MHz?
Despite objections from the Department of Transportation (DOT), the FCC voted today to allow unlicensed use of 45 MHz of spectrum in the 5.9 GHz band. The spectrum was originally dedicated to intelligent transportation systems (ITS) over 20 years ago, but few such deployments have occurred.
