Going Lengthy – HF Radio Frequencies
For really lengthy vary communications, you could function within the HF bands. These excessive frequency bands vary from 1 to 30 MHz and are succesful, underneath the suitable circumstances, of transmitting a whole lot and even hundreds of miles.
This offers you the potential to contact different HAMS many miles away, and even on a special continent.
Studying the Bands
HF frequencies are divided in to bands and every nation determines which areas of those bands licensed HAM radio operators can entry. Within the U.S., the band plan chart issued by the FCC lays out like this:
- 160 Meters (1.8 MHz) – 1.8 to 2.00 MHz
- 80 Meters (3.5 MHz) – 3.50 to 4.00 MHz
- 60 Meters (5.3 MHz) – Divided into channels allotted to particular frequencies between 5.3305 and 5.4035 MHz
- 40 Meters (7 MHz) – 7.0 to 7.3 MHz
- 30 Meters (10.1 MHz) – 10.100 to 10.150 MHz
- 20 Meters (14 MHz) – 14.000 to 14.350 MHz
