In the last 24 hours on 136kHz there have been several Opera decodes
flagged up with question marks (and shown in red), indicating they
need further examination to determine whether they are genuine true
decodes.
Amongst the obviously false ones are SV8CS and 2E0ILY reporting
JA8SCD who claimed to be running very low power. SV8CS was also
reported by JA8SCD/1 but was not reported in Europe at the same time.
A couple of spots of UA4WPF are unlikely, especially one by JA8SCD/1
over a daylight path.
More probable are various reports of LA3EQ's QRP tests overnight by
DL-SWL, though the report from RW3ADB may not be good.
The reliable, true Deep Search reports (shown in green) included
SV8CS de SP5XSB, RN3AGC de 2E0ILY and RN3AGC de G0KTN, which are all
paths that would not have been reported without Deep Search.
Just looking at a single night it appears that the current system of
red = 'probably not' and green = 'highly likely' (my description)
works well.
A couple of times, a station was decoded by Deep Search, and then 10
minutes or so later were reported by the same station using regular
Op at a much higher S/N. This effect is also seen on OPDS.
The only minor problem is that reports of your own signal are also
shown in red, which is slightly confusing.
So far, so good.
