Upper and/or Lower SSB Quest. ? And 2182 Quest. ?
Hello:
Still a newbie at this; probably always will be. Regarding the Maritime channels, 2182 for initial emerg. calling, and I think 2160 ? which they switch to after, I believe both of these are SSB ? Correct ? If so, USB or LSB ? Is AM (or fm) ever used for these freq's ? Is there a "general rule" regarding when Upper SB is used, and when Lower SB is used ? e.g., below any frequency, it might be more common to use..., etc. Thanks, Bob |
