Every time I post anything about the Nationals’ TV ratings — and I did so again this week — at least one person seems to ask a question about the team’s radio ratings.

Well, those people are in luck, because I finally have some numbers.

These numbers — which come via a radio industry source — are for games from May 1 through May 23, which is the most recent reporting period available. They include the audience for WJFK, and for both WJFK and WFED on days the games appeared both places.

On average, about 70,400 listeners ages 6 and older tuned into at least five minutes of each Nats game in that period. The combined quarter-hour share was 5.26, meaning for an average 15-minute period during a Nats game, 5.26 percent of the radio audience was tuned in to Charlie and Dave.

While I don’t have an exact number to compare this to for past seasons, the source said the ratings are up “considerably” this season.

Remember, the TV broadcasts on MASN, MASN2 and WDCW are attracting an average audience this season of 52,400 households in the D.C. market. Please do note the difference between “listeners” for the radio number, and “households” for the TV number.
