Down the A55 road...

Yesterday, I took an hour to receive some WSPR from Penmaenmawr sea front, where you can park a car very close to the sea, with an open aspect from SSW to ENE.

Fantastic, drive-up and operate coastal location - Penmaenmawr, North Wales (IO83ag).

A potential disadvantage of this position, though very convenient, was that it lies right next to the A55 highway, carrying a large volume of traffic.  Surprisingly, only the very occasional car produced any ignition noise - and most of those were actually very new, premium brand cars!

The result from this site proved to be exactly the same as the previous day's outcome from the west Anglesey coast - with the crucial exception that there were a very significant number - 38% - of stations heard at the coast that were not heard at all by my delta, back home.
