A couple of tentative mystery logs for tonight , April 5, before

13710 – I am not sure if India has reactivated this frequency at this
but I was hearing a definite Chinese language program here peaking above
the noise at 0048 GMT . Mostly talks by several announcers, om & yl ,
an occasional mx bumper , possible Chinese style mx , between segments.
There were a couple of ad or promo type announcements right before 0100
followed by time pips , about 25 seconds early but silent until TOH, then
signal faded well below the noise. At 0114 the signal cut off for about
15 seconds then returned but the level was just to low to compensate for
the noise and atmospheric effects on the signal. Could be a CNR jammer
against a past AIR program that isn’t there anymore.
