Bicycle portable in Blackpool

David G4AKC has been on his bike and working some excellent DX (like VK/ZL) on SSB and CW on 20m from his bike parked up next to the seaside in Blackpool. He uses and Alinco DX-70 on battery power with a  home made top loaded 3.5m long vertical against a tuned frame, and operating "over the sea water".  He says several QSOs were possible at the 1W level.
