I'm pretty certain that they're not running ND, then. I can hear them 
here in Rochester with the oldies, but the signal's easily nullable.

Here's my best guess as to what's been happening in the last couple of days:

When CKDO went ND on 1350, they probably disconnected the old 1350 
phasor and the antenna tuning units at the towers that weren't being 
used. That bought them a few days to retune those towers for 1580 and to 
begin connecting the new 1580 phasor.

Once 1350's ND signal left the air this morning, that would have been 
the time to retune that remaining tower for 1580.

What we're hearing now, first with dead carrier and now with audio, must 
be the tuning-up process for the new 1580 signal.

There's been no simulcast on 1350 and 1580 because there's just one set 
of transmission lines from the transmitter building to each tower, and 
no point spending the $$$ on the combiners and filters they'd need to 
install to send both 1350 and 1580 down that same set of lines.

I'd bet a pretty large chunk of CKDO's audience is over on the FM by now 
anyway, and will never even realize the AM has moved.
