Morse code required for the privilege to use the HF bands. Until 2000, proficiency at the 20 wpm level was required to receive the highest level of amateur license (Amateur Extra Class); effective April 15, 2000, the FCC reduced the Extra Class requirement to five wpm. Finally, effective on February 23, 2007, the FCC eliminated the Morse code proficiency requirements from all amateur radio licenses. While voice and data transmissions are limited to specific amateur radio bands under U.S. rules, Morse code is permitted on all amateur bands—LF, MF, HF, VHF, and UHF. In some countries, certain portions of the amateur radio
Morse code for non-Latin alphabets not have a Morse equivalent, with Е used instead. Hebrew letters are mostly represented using the Morse representation of a similar-sounding Latin letter (e.g. "Bet" ב≡B); however the representation for several letters are from a Latin letter with a similar shape (e.g. "Tet" ט ≡U, while "Tav" ת≡T). See also The following telegraph code table is adapted from one given by Ashok Kelkar, where the Latin letters are encoded as per the International Morse code standard. Some variations on this code exist, and there have been some attempts to introduce other telegraph codes to add efficiency and make it suitable
