Building the PA8W Radio Direction Finders


Here you can find all about the high performance RDF41 and RDF42 radio direction finders,
about its doppler and amplitude VHF and UHF antenna arrays for fixed and mobile applications,
and about the excellent mapping and networking solutions offered by Jonathan Musther's RDF Mapper.
