The 2-meter amateur radio band is a portion of the VHF radio spectrum that comprises frequencies stretching from 144 MHz to 148 MHz [1] in International Telecommunication Union region (ITU) Regions 2 (North and South America plus Hawaii) and 3 (Asia and Oceania) [2] [3] and from 144 MHz to 146 MHz in ITU Region 1 (Europe, Africa, and Russia).
A Restricted Grade licence holder was previously authorized the use of radio telephony emission on frequency bands below 30 MHz on submission of proof that 100 contacts have been made with other amateur operators using CW (Morse code). [2]
The 2 200 metre band is available for use in several countries, and the 2007 World Radiocommunication Conference (WRC-07) recommended it as a worldwide amateur allocation. Before the introduction of the 2 200 metre band in the U.K. in 1998, operation on the even lower frequency of 73 kHz, in the LF time signal band, was allowed from 1996–2003.
The first signal report format code may have been QJS. [citation needed]The U.S. Navy used R and K signals starting in 1929. [citation needed]The QSK code was one of the twelve Q Codes listed in the 1912 International Radiotelegraph Convention Regulations, but may have been in use earlier.

Several countries in ITU Region 1 have access to frequencies in the 70 MHz region, called the 4-meter band. The band shares many propagation characteristics with 6 meters. The preferred location for beacons is 70.000–70.090 MHz; [5] however, in countries where this segment is not allocated to Amateur Radio, beacons may operate elsewhere in ...
for all letter-digit-digit-letter callsigns, if the first character is B, F, G, I, K, M, N, R, or W then it is a 1×2 call sign; PNSSS, 1×3 call sign these have the same precautions as 1×2 call signs to prevent confusion with 2×2 format; PPNSS, 2×2 call sign these have the same precautions as 2×1 call signs to prevent confusion with 1×3 ...
