Typically this can be 3.5 – 3.8 MHz , although in North America, frequencies up to 4.0 MHz can be used, although there is a broadcast band allocation above 3.8 MHz. This ham radio band can be quite noisy, especially at night as it is shared with other services and this can make it very busy.
Read moreWhat HF frequency is best?
HF users have found that using a frequency that is the MUF times 0.85 gives the best chance for good results. This is called the frequency of optimum transmission (FOT).
Read moreWhat frequencies are in the HF band?
High-frequency (HF) radio is in the 100- to 10-metre wavelength band, extending from 3 megahertz to 30 megahertz . Much of the HF band is allocated to mobile and fixed voice communication services requiring transmission bandwidths of less than 12 kilohertz.
Read moreWhich has better range 2m or 70cm?
2m can pass around trees, leaves and other such foliage easier than 70cm which makes it good for rural settings, but 70cm is better if you’re in a place with lots of buildings since it can pass through doorways and windows easier.
Read moreHow far can you talk on 70 cm?
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.
Read moreWhat is the most popular ham radio band?
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.

In particular, the 2m band extends from 144 MHz to 148 MHz . The FCC Rules say that any mode (FM, AM, SSB, CW, etc.) can be used on the band from 144.100 to 148.000 MHz. The FCC has restricted 144.0 to 144.100 MHz to CW operation only.
