== Shortwave -vs- Longwave ==Radio wavelengths longer than 1000 meters (frequencies less than 300 kHz), including the ITU's low frequency (LF) (30–300 kHz) and very low frequency (VLF) (3–30 kHz) bands. Sometimes part of the medium frequency (MF) band (300–3000 kHz) is included.Radio wavelengths generally 1.6–30 MHz, just above the medium wave AM broadcast band, the ITU Region 1 defines the span 1.6–30 MHz, just above the medium wave band, which ends approximately at 1.6 MHz.To simply, if it's below AM Broadcast they call it LONGWAVE and if it's the portion above it is SHORTWAVE. A typical shortwave broadcast receiver doesn't include longwave reception. Consumer radios capable of both typically receive the longwave frequencies 100-519 kHz, just below the AM band (520-1710 kHz) like the longwave signals used by those interested in low-frequency experimental radio (LowFER) communications as well as ITU Region 1 broadcasters in Europe to China. MF - Medium Frequency (535-1705 kHz) === LF - Low Frequency (30–300 kHz) below shortwave ====== MF - Medium Frequency (535-1705 kHz) below shortwave ===shortwave:=== Extended MF - Medium Frequency (1705 kHz - 3000 kHz) also shortwave radio ====== HF - High Frequency (3000–30000 kHz) also shortwave radio ===
