HF Terms

--------

CW - Morse Code (Continuous Wave), a transmission mode consisting

of long and short tones known as dits and dahs (or dots and

dashes). This mode takes up very little spectrum space and

provides for extremely long distance transmissions due to

a number of factors such as the ability of the transceiver

to focus all the energy on a very narrow transmission.

 

USB - Upper Sideband, a variation of the single sideband voice mode

(Single sideband sounds very muffled if if receiver does not

support single sideband mode) Single sideband takes up half

the space of a normal AM transmission and also provides for

much longer distance communications than normal double

sideband AM)

 

RTTY - Radioteletype, text communication between teleprinters or

computers

 

MARS - Military Affiliate Radio Station, radio stations aiding ship

to shore communications, especially between sailors and their

families. (NOTE: A valid MARS licence is required to operate

on MARS frequencies.)

 

Amateur Radio - Radio Stations communicating *noncommercial* information.

Amatuer Radio Operators have many Amateur Radio Bands

spread throughout the spectrum. Amateurs are a vital

source of communications in emergencies but Amateur

Radio is an exciting hobby even when there is no emergencies.

Amateurs have many different authorized communications

modes such as CW,USB,LSB,AM,FM,RTTY,AMTOR,Packet (computer

to computer error free communications), SSTV (slow scan

television), FSTV (fast scan television like normal TV),

and more. Amateurs have built amateur satellites (for

extremely long distance communications even on VHF and UHF)

as well as repeaters to increase the communications range

of their handheld amateur radios. (NOTE: A valid amateur

radio licence is required to operate on amateur bands.)
