Follow-up To NERW Piece On W221CH

[Kevin Vahey]

One thing I was curious about why.

Back in 1967 when WRKO-AM came to be they then simulcast AM on FM from
6AM to 6PM and then ran ARKO for the other 12.

The AM jock would then cut into FM at the top of the hour and simply
say WRKO-FM Boston. I have clips of Arnie Ginsburg and Chuck Knapp
doing this.

So was a live ID required back then or was this possibly an AFTRA
concession by RKO General.
