Note: 29100 to 29700 is the only segment of the HF bands where the wide bandwidth required by FM transmissions is permitted; on all other bands, the bandwidth limits mean that "All modes" would exclude FM | |
“Narrow band modes” in the above table refer to modes with a maximum bandwidth of 500 Hz | |
Below 10 MHz use lower sideband (LSB), above 10 MHz use upper sideband (USB) |
