Hi Mike,

The ....... "Red = probably not" ..... should show up as Orange.

Quote from Jose's email :-
This test version show green spots with 2 or more decodes
orange spots with only one deep search happen


It is on mine & cannot be mistaken for red.

Monitor colour adjustment required ??
But not always possible as the feature may not be in the monitor set up 
menu.

Amongst the obviously false ones are SV8CS and 2E0ILY reporting

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.

Mike, G3XDV
