UNID on 6770,05 kHz on 28 Nov 2017 :
just a trace (weak carrier) at 2235-2254 UTC, with a bit of music at 2242 UTC.
A few weeks ago, I asked about that 6770.05 and got here a reply : it could well be that OTR (including errors on the last figure of the frequency, i.e. a couple of tens of hertz).
I understand that OTR is very low power station, so maybe I heard something different on this side of the pond.
I will try again...
