These ``wobblers`` from Cuban transmitters have been reported for many years on many different frequencies by North American DXers in MW groups. according to Brett`s theory. Nothing to do with solar activity (except possibly enhancing southern signals). 73, Glenn Hauser

The noise sounded similar to what I heard on the FM band beck in the 80s during a period of high activity. Here is a space weather link to activity on 27 June (UTC) http://www.spaceweather.com/archive.php?view=1&day=26&month=06&year=2015 depending on whether the time you quoted was local or UTC there might be a tie in. The piece that could be relevant is below the blue image. Paul, NZ On 28/06/2015 12:48 p.m., [email protected] wrote: CUBA?? 1000 Apparently one of the Cuban stations, R. Granma or R. Artemisa here with a strange effect on the carrier sounding like either a Rap DJ doing a "turntablism" or someone warping a hand saw. Noted intermittently from 0915-1000, but best heard around 0916 and 0927. Brett Saylor mentions the theory is that a power fluctuation in the grid is causing the transmitter carrier to "wobble".
