Frequency Range 3 kHz – 250000 MHz
Mode CW
Modulation OOK

Is 40m USB or LSB?

You will notice that on 160, 80 and 40 meters, LSB is mostly used and on the higher frequency bands, USB is used. This is a leftover from the early days of SSB when radios were designed a certain way, when SSB was in its infancy. Operating habits will not likely change in the future.

What frequency should be used for QRP CW?

QRP Calling Frequencies

Band CW Phone
12m 24906 kHz 24950 kHz
10m 28060 kHz 28385 kHz 28365 kHz (EU)
6m 50060 kHz 50185 kHz
2m 144060 kHz 144285 kHz

What is CW signal?

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 in Morse code?

Essentially CW refers to a Morse transmission using a radio signal – the abbreviation coming from the fact that it uses a Carrier Wave, or Continuous Wave that is interrupted. In this way, CW can be used to denote a simple Morse transmission that interrupts the carrier to give the required Morse characters.

What is 12m band?

12 meters – 24.89–24.99 MHz – Mostly useful during daytime, but opens up for DX activity at night during solar maximum. 12 meters is one of the WARC bands.

Is 80m USB or LSB?

SSB Frequency Lists

Basic Frequency Lists and Bands for Listening to SSB (in KHz)
160 Meters 1850-2000 LSB
80 Meters 3600-4000 LSB
60 Meters USB
40 Meters 7125-7300 LSB

Is 80 meters USB or LSB?

Lower band edge The lower edge of 80 meters is predominated by CW emissions, with the lower 10 kHz (3.5–3.51 MHz) primarily used for long distance communications. It is common for illegal marine operations, generally using USB voice, to occupy frequencies on the low end of 80 meters.

What is the calling frequency on 20 meters?

The 20-meter or 14-MHz amateur radio band is a portion of the shortwave radio spectrum, comprising frequencies stretching from 14.000 MHz to 14.350 MHz. The 20-meter band is widely considered among the best for long-distance communication (DXing), and is one of the most popular—and crowded—during contests.

What frequency is the 10 meter band?

28.000 to 29.700 MHz
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 40 meter band on the radio?

40-meter band. 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.

How many meters in a CW band?

Band CW SSB Novice CW Europe CW 160 Meters 1.810 1.910 80 Meters 3.560 3.985 3.710 40 Meters 7.040 7.285 7.110 7.122 7.030 30 Meters 10.106

What is the novice frequency for 40 meters?

I have been looking at old forums on which frequencies are for the novice portions and i have found that for 40 meters the novice portion was 7.025 and 7.125 . Is It the same area on 20 meters?

How far above the channel frequency should CW emissions be centered?

CW and digital emissions must be centered 1.5 kHz above the channel frequencies indicated in the above chart 40 Meters (7.0-7.3 MHz) 30 Meters (10.1-10.15 MHz) 20 Meters (14.0-14.35 MHz)
