not sure--when was the last time someone heard them? I did a quick websearch and found the following from Fybush's site, 2 years ago:
>WDIS (1170 Norfolk) faces a $16,500 fine from the FCC to clear up a paperwork mess surrounding its 1998 license renewal - or lack thereof. WDIS never applied to renew the license that expired April 1, 1998, and it didn't answer the FCC's inquiries about it, either. The WDIS license was cancelled April 30, 1999, and only then did Al Grady's Discussion Radio file a petition for reconsideration and get the license reinstated, telling the Commission that it had been sending its paperwork to an outdated address.
Under radio-locator.com, they don't show up either under "Norfolk MA" or "WDIS"
