Re: [IRCA] [NRC-AM] Domestic MWDX to Enid OK, December 5-11, 2014



That is generally correct. If a station has a higher night power they have
the option to use it instead however there are some special exceptions
where a different pattern is also specified for the PSSA or PSRA which is
more restrictive than the night pattern. This is to prevent unwanted
twilight interference from sunrise or sunset skip.
