Propagation Verification Claim Form

Notes: (1) /p means portable operation.

(2) /# means operating in another state or district.

Propagation modes are tropospheric refraction and ducting (including line-of-sight paths), divided into in four categories: Tropo (A) (tropospheric modes across the Atlantic, Caribbean, and Gulf of Mexico); Tropo (C) (tropospheric modes across continental North America; Tropo (E) (tropospheric modes across Europe); 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); and Rain scatter (precipitation scatter).

TX modes left blank are unknown at the time of publication.
