DEFINITIONS: | ||||
All modes – CW, Phone and those other modes that might be stated as preferred modes or listed | ||||
Narrow band modes - All modes up to 500 Hz bandwidth, including CW, RTTY, PSK, etc | ||||
Digimode - Any digital mode within the relevant bandwidth, like RTTY,PSK, etc. | ||||
Image mode - The analogue or digital image modes within the relevant bandwidth, for example SSTV, and including FAX | ||||
( 1 ) - Lowest dial setting for LSB: 1843, 3603, 7043 kHz | ||||
Sideband usage - Below 10 MHz use lower sideband (LSB), above 10 MHz use upper sideband (USB) | ||||
