ZAP? Has the PA a fault or have you just switched it off?

Apart from the directional antenna of Paul Nicholson (which has some 
gain and so the ability to reduce the noise) i think a main difference 
and advantage for him is the QTH. In north UK there seems to be much 
less QRN compared to central EU! Furthermore he is relatively outside in 
the landscape, not in the center of a city. I do not think that the high 
quality sound card he is using makes the difference, at least at 8970 
Hz. Regarding noise, TF3HZ must be in an even better situation.
