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 are the 2 meter simplex frequencies?
| 144.00-144.05 EME (CW) | 146.40-146.58 Simplex | 146.52 National Simplex Calling Frequency | 146.61-146.97 Repeater outputs | 147.00-147.39 Repeater outputs |

What is the national simplex frequency?
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 simplex frequencies used for?
Simplex radio communications is the simplest means of communications. It uses a single
frequency for the transmission and receiving of a radio signal
. When you are using a little store-bought FRS walkie talkie, you are communicating in simplex mode. Simplex is also used in amateur communications.
What is the most popular ham 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.
How far can you talk on 2 meters?
On VHF frequencies such as 2-meters, antenna height greatly influences how far one can talk. Typical reliable repeater range is
about 25 miles (40 km)
. Some repeaters in unusually high locations, such as skyscrapers or mountain tops, can be usable as far out as 75 miles (121 km).
What are MURS frequencies?
The Multi-Use Radio Service (MURS) uses channels in
the 151 – 154 MHz spectrum range
. … MURS is authorized five channels that were previously in the industrial/business radio service and were known as the “color dot” frequencies in Part 90 of the FCC rules.
Do you call CQ on 2m?
The conventional wisdom in amateur radio is that
we should not call CQ when
using FM on the VHF and UHF bands, especially on repeaters. FM communications are often quite clear and noise free, which also helps. …
Who uses 1.25 meter band?
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.
Is 70cm better than 2m?
2m- Good all around band for talking/chatting, but since its VHF, signal travel depends on what’s in its way and the power output of the radio.
70cm- Good band
, since its UHF its good to have in the city or around tall buildings or inside of buildings because its wavelength penetrates obstacles better.
What are simplex channels?
Simplex communication is
a communication channel that sends information in one direction only
. The International Telecommunication Union definition is a communications channel that operates in one direction at a time, but that may be reversible; this is termed half duplex in other contexts.
What frequency is 70 cm?
The 70-centimeter or
440 MHz
band is a portion of the UHF radio spectrum internationally allocated to amateur radio and amateur satellite use. The ITU amateur radio allocation is from 430 to 440 MHz; however, some countries, such as the United States, allocate hams 420 to 450 MHz.
What are kdr444 frequencies?
- 2182 kHz.
- 500 kHz.
- Coast radio station.
- Marine VHF radio.
- Maritime mobile amateur radio.
Can a ham radio be traced?
When it comes to an Amateur Radio license in the US,
yes you can be tracked by that since it’s public record
.
Can a Ham Radio talk to a CB radio?
Can ham radio be used as a CB radio? Generally, the
answer is no
. … If a licensed amateur radio operator wanted to speak on a CB frequency range, the operator would need to use a CB radio. That said, amateur radio can be used in many applications where people currently use CB radios.
How far do Ham radios reach?
As I’ve mentioned, Ham radios have an average range
between 2 miles and 18 miles
. But, if you’ve recently purchased a Ham radio (especially a handheld unit), the manufacturer might claim that you can get substantially more range than 2-18 miles. In fact, many 2-way radio units claim as much as 36 miles of range.
