Propagation Classifications for VHF/UHF -- Propagation modes are
tropospheric refraction and ducting (including line-of-sight paths), divided
into in three categories:
Tropo (A) (tropospheric modes across the Atlantic, Caribbean, and Gulf of
Mexico);
Tropo (C) (tropospheric modes across continental North America;
Tropo (P) (tropospheric modes across the Pacific);
Aurora (auroral scatter);
Auroral E (auroral E);
Sporadic E (sporadic E);
FAI (E-layer field-aligned irregularities;
IFS (ionospheric forward scatter);
Meteors (meteor scatter);
TE (transequatorial field-aligned irregularities);
Rain scatter (precipitation scatter).
