I have not had much success in getting a verification from WRCA, despite many tries over the years. WRCA is an easy catch and can be easily received on 1330 kHz here, it is by far the most common station on the frequency. A power of 25 kilowatts daytime and 17 kilowatts nighttime from their transmitter in Watertown outside Boston means they are widely heard.
WRCA has carried a variety of formats during the last decade, but since July 2017 the station has broadcast financial news from Bloomberg Radio. Michael Lysak of Bloomberg Radio kindly confirmed my audio recording from Lista in March. When I heard WRCA, the station had many local station identifications and announcements in addition to the network programming.
