[UK-CONTEST] Aircraft Reflection

[Rob Harrison]

Hi Ray & Ken,

I've long maintained that most of our everyday contacts are via A/S and not 
true tropo'. Like Ken, during the ash cloud incident, I too found that most 
of the beacons had disappeared and contacts were more difficult.

Monitoring HB9HB from here in JO01, I can hear it on a rough 2 minute cycle 
at 419, during the event it wasn't there at all. The mid point is above 
Reims. Looking at air traffic over that area, the prevailing traffic is not 
in a favourable direction for reception, being mostly E-W or W-E, it needs 
to be NNW-SSE and vice versa.

The only way under normal band conditions to hear GB3ANG is via A/S, nothing 
heard during quiet periods at all.
