In the past 5 or 6 years I developed and built a number of VHF/UHF radio direction finders, based on the pseudo doppler principle and recently the Amplitude principle.
All designs are -like all professional designs- soft-switching , so without the high noise level found in all cheap hard switching designs, which gave the doppler RDF a rather doubtful reputation in the amateur world.
On my website I share information about easy to build antenna arrays and RDF processors.
And for those without electronic background there is an almost ready to use, microcontroller based kit with semi-professional performance, able to work as a pseudo doppler RDF as well as an Amplitide RDF, depending on the type of antenna array used.
Members of this forum might be interested in this matter.
If so, just google my call PA8W.
