Ham band propagation

WebThe 80-meter or 3.5 MHz band is a band of radio frequencies allocated for amateur radio use, from 3.5 to 4.0 MHz in IARU Region 2 (consisting mostly of North and South America), and generally 3.5 to 3.8 or 3.9 MHz in Regions 1 and 3 (the rest of the world) respectively. The upper portion of the band, which is usually used for phone (voice), is sometimes … WebAug 14, 2024 · Now with declining "propagation" I still love 30 meters. In fact, last week, while driving through seven states, I made 191 mobile QSOs on 30 meters in four days. Of course I was mostly running counties, but there were also a fair number of casual QSOs on 30 meters while driving between run counties. Some say the bands are dead!

Six Meters: An Introduction

WebSingle hop propagation already starts at 70 in lower latitude areas. Worldwide long distance propagation (DX) may turn up already with a solar flux at 120. From experience, an average solar flux of 170 seems to be ideal for 10m-20m bands QRP DX with good possibilities during these conditions to reach every possible part of the globe with a ... WebThe 15-meter band (also called the 21-MHz band or 15 meters) is an amateur radio frequency band spanning the shortwave spectrum from 21 to 21.45 MHz. The band is suitable for amateur long-distance communications, and such use is permitted in nearly all countries.
