ALLO AM Daytime Groundwave Preliminary Study

ALLO lists AM stations that may be considered by the staff during a daytime groundwave analysis for an AM station proposal. ALLO does not make actual groundwave calculations. This preliminary study simply checks for stations within a fixed distance, depending on the frequency difference:

The Commission's staff may consider additional stations (stations not on this list) as necessary.

For AM stations on frequencies where one is twice the frequency of the other, or where the difference in frequencies is close to the AM band intermediate frequency (455 kHz), refer to 47 CFR Section 73.182(s).

ALLO uses the AM Query to generate and present results.
