http://radio-locator.com/pats/WDIS_AM_LD.gifWDIS: Interesting signal pattern. They're a daytimer though.
WCAS used to run funny little tapes when they'd sign off.
(and is it 1560 you mean should go urban...?)
And in Nahant (across the water) I used to pick up WJTO 730 who'd have a recording
saying they were going off, but tune to their sister station "Y-106" (WIGY-FM, now
religious?) for more music. When up in Maine some months ago I was driving around
and Mr Bittner came on explaining that JTO had to really cut its power as it was sunset,
and "for those who can't pick us up after the switchover, we invited you to tune in
tomorrow".
