Even though the few remaining RDF beacons slowly going away AM stations remain and seem likely to for a long time. I don't know about other folks' units but mine picks up AM so I can use broadcast stations as beacons.
Speaking of RDFs, while I have one and know how to use it generally, there is one feature specifically I don't understand, the sense antenna. Yes I know it helps resolve the 180* ambiguity of the nulls. The questions is the mechanics of it. My unit was a gift from a friend and did not come with a manual. I assume procedures for use are:
1] Tune the station
2] Find a null
3] Erect the sense antenna vertically
4] Press the sense button
5] Find the other null
6] Press the sense button again
Assuming this is the correct I don't know what change to look for between the 2 nulls which would indicate which is the correct direction.
