Comments should be used mainly to request/propose clarification of a question or answer. | |

I am wondering: do you have numbers for "fractional channel bandwidth" across bands? in Europe / UK, among the HF bands, the 60m band allows 12.5kHz, while all other (HF) bands top out at 2.7kHz (or 6kHz for 10m), which makes 60m attractive? fwiw, 2m/70cm allows 25kHz, and only 23cm allows 150kHz, also: I assume 1 sender may only use 1 channel concurrently? what's "the" bandwidth of a sender sending in 2 slots each say 12.5kHz wide, but not adjacent, say "channel 0" and "channel 10"? | |
