KCH is no longer listed among the unlicensed, low-power “Pirate Radio Stations” operating in Brooklyn. The only current listings focused on the frum velt in NYC are the following:
91.9 – Mystery Orthodox Jewish Station
95.1 – Jroot Radio
105.7 – Radio Moschiach
Its possible that some of the pirate stations have morphed into online podcasts available on apps that you can download; the stations I noted above are very low power FM broadcasts that are only accessible in relatively close proximity to the transmitter.
