Gerton, PD0G built this beauty of the RDF41-kit:
is a coastal observation post run entirely by
They enhance and support the work of the coastguard using optical
instruments and radio equipment.
To do that, they added a V2,3 doppler to their toolbox.
As they don't have a electronic engineer in their crew I built a plug
and play RDF for them including the ready to use VHF array.
The array dictates the size of the shipment and luckily the necessary
box size was just within the (100x50x50cm) max size permitted to send
by international mail.
here's the RDF in the station's console:
claim an accuracy within about 2 degrees which is extremely good
for a 4 antenna doppler.
However, a more ideal environment is hard to find, as this is what they
see from their observation post:
station building is one of the many observation post
built for WW2, now adapted for purely peaceful purposes.
It feels good that I was able to help them realize their
doppler Radio Direction Finder.
