WXKS (AM) does come in at night in Beverly, half decently; though I notice late at night near my workplace in North Reading (and I do work nights) it can be shaky, fading in and out.

Shows patterns (again not totally accurate) including their construction permits for day and
night/direction patterns.
Some people on Facebook were saying, as one would expect "1200 should improve its signal".
I pointed out they've done what they could and probably can't do much more due to other
stations on or near their frequency. Some people actually asked "1200, is that AM?" When some
people said they couldn't pick up 1200 well in southern NH or in RI, I suggested they contact CC
and ask them to put the show on WGIR and/or WHJJ. People listening on a Walkman or in buildings are going to have trouble but at least one person said they were at work but listened online. And then there are all these I Heart Radio phone apps, and HD radio. For me in Beverly, the 107.9 HD2
(WXKS) comes in fine, as does the WBZ-FM HD3 (with WBZ AM). The HD2 of WKAF 97.7, with
WEEI, comes in half decently while I can't pick up WAAF's HD2 (WEEI) or HD3 (WRKO) at all. In fact WAAF itself barely comes in around here.
