Hi Topband Gang, Thanks to everyone that reported reception of the signal. It stopped at 7:54am EDT. Based on preliminary data which probably did not have enough resolution it looked like it was originating from Ohio or Pennsylvania. Hopefully it does not reappear. 73, Don (wd8dsb) On Fri, Dec 11, 2020 at 7:31 AM Don Kirk wrote: > Hi Dave, > Thanks and glad others are hearing it too.

It is 10db over S9 here in central Delaware, peaking on NW Beverages. Much weaker spur from it covering 1823.5 as well (strong enough to cover HL5IVL). Jon P.

Re: Topband: I identified signal on 1.825 MHz this morning
Hi Dave, Thanks and glad others are hearing it too. I just looked at it on an SDR receiver and it has a bandwidth of 400 Hz, and it's using two different frequencies spaced 200 Hz apart. Very Strong here near Indianapolis. Peaking 25 dB over my noise floor.
