27430 FM [141.3 Hz CTCSS/PL tone] 01/17/2016

The band is open a bit right now, not as much as it has been - however I have heard a CW ID on this frequency several times today (and on the previous couple days) in FM mode.  IDs are transmitted with a PL tone (141.3 Hz).  Maybe somebody is running a (legal) repeater on this frequency and I'm hearing the ID.  Most of the time when I hear a repeater ID it does it without whichever tone the system is using (so as not to annoy the users with a CWID).  

Usually I hear SSB traffic on this frequency and those around it so hearing FM here is a first for me.  Most FM I hear is UK "27/81" FM 27601.25-27991.25 and without PL tones.  27430 is a legal business frequency (as are 27450, 27470 and 27490) as per FCC rules Part 90.  

Another CWID heard at 2004 UTC
