WW2 Germans radio direction finder used.

[@cringemaki]

It is scary how folks back in the 40's had this kind of equipment. Being a spy and having the thrill of Germans possessing a precise device to find you out; must have been "fun". Excellent video, sir!

[@LA6NCA]

Yes, and then many of the radio agents were unaware of this radio directio finder capacity of the Germans. They didn't learn much about this in radio training in England. I will cover this in another video later.

I was an Electronic Warfare Officer flying reconnaisance missions in the analog days. The navigator logged the exact route we flew. I operated a radar receiver fed by a rotating dish. The signal of interest was fed into equipment which showed pulse width, pulse recurrence frequency and other data from which maintenance status of the transmitter could be determined. A direction finding (df) bearing would be logged with the time. At least three df bearings would be taken. After landing a mission debriefing was held and the crew activity reports provided which also included other operators data. The ground analyst would take the data and plot all the provided info which showed location and the "fingerprint" of that system. If it was moved to another location, it could be identified where it had been positioned. It was time consuming but it was the best info available at the time. We are now in digital times and signals hit an antenna in an airplane, ship or satelite, prosessed through computers and relayed direct to intel processors. The navigator has been replaced by a GPS compterized system and so have I. KE5UPM

A few days ago, this video came back to my mind, since I needed to trace down the source of a very annoying noise in my neighbourhood, which was jamming the whole RF spectrum all the way from 150 to 3000KHz. All I did was to walk up and down the street with a portable AM radio, but it took me some time to find a good null point, since the noise was really strong. In the end, the source was inside a newly-established mechanical shop, a few houses apart from mine. After talking with the owner, I found out the culprit was a compressor motor, which he agreed to fix after I proved him he was against the law for producing so much electromagnetic pollution! By the way, this video (and all the others) are amazing. This is what gives me joy for being into a cool hobby as this!

Torbay also landed various types of agents and special forces in the Mediterranean and in Malaya. / My mother never said a single word about her war, but after her death, something prompted me to start asking questions. I found a clear link to French Section of SOE, explaining her intimate knowledge of the Beaulieu area in southern England, used as their training area, and for sending agents by air to France. / So I really appreciate your video, Helge. It is one thing to read of RDF in books, but quite another to see it in action, and using the original kit. I watch some of ww2historyhunter's videos, where he explores the many German bunkers.
