A couple of comments.

While opinions about accuracy vary, no numbers have been posted. Come
Spring, it would be great to see a couple of sailors with RDF's take
them out of hiding and check their accuracy against their GPS.

No RDF is going to provide a position within a few meters except by
accident. but most of us work really hard to avoid needing that kind of
accuracy.

i'm going to try it.

i'm just going to get some of this RDF equipment and try it out on land
while using my handheld GPS and some maps to check against. or maybe
in the truck, i have an icom radio in the truck i can use with an
antenna, it has a strength meter built into it. i'll have to find a
good directional antenna to use, or make one. i'm going to check
around for some of the actual RDF equipment used in marine navigation
too though, i bet there is tons of this stuff in people's garages just
waiting for someone to find. when i was reading it looks like you can
also find old RDF/ADF equipment out of old airplanes too to play with,
and these have needles that turn to whatever transmitter is using the
frequency you tune too! fun stuff.
