most of the RDF equipment i've seen looks really old!

That's because it has been virtually obsolete for over 20 years, ever
since LORAN-C became widely available and affordable back in the early
'80s. Truth is, RDF was never all that accurate or reliable, it's
just that it was the only affordable electronic aide to navigation for
many years. I still have mine in the garage and I'm not expecting it
to move anytime soon. The best backup for GPS is another GPS, and
some spare batteries.

I have an old RDF and have wondered if it could be useful for any
purpose. For example, getting a bearing on a VHF radio transmission
from a boat in distress. Or, perhaps, getting a bearing on an AM or
FM radio tower or a FAA tower. Any conceivable use for it or fun to
be had with it, or is it time to send it to Davy Jones?
