Night life... the signal is coming from the base station... please continue collecting frequencies in your head and not here until you have some results remember this isn't the thread for your theories.. and it does de rail it from real members sometimes please do not clutter this thread. Thanks again

So hans looking at the pic i say it would be safe to say that with the two inserts its just a path in and out from the mic/ receiver. Now if im not mistaken this system was full duplex as explained.. To folks who don't know the term full duplex as opposed to half duplex would mean that both parties can talk at the same time and hear each other at the same time. Vs one party listening and then speaking.  Now im curious to the lc calculations he used to determine the coil sizes on the two rods vs the base station output ... Secondly with two inductors ... I bet there are 2 different size coils for each "mobile unit" smaller is the in to one side of the mic and a larger coil on the other side .. i could be wrong but what else would the purpose be for the different sizes on those spikes...  The patents describes  a square wire/coil around the perimeter of your service area and apparently dropping these rods in within that area and connecting to the mic/receiver  is the jist of it.

G'day Joe and all.

The system you are describing is a patent that Stubblefield patented after he had lost the rights to the system you see displayed here.

Apparently he signed over the rights to the original system to a company in return for stock. The company was involved in a share swindle and Stubblefield wound up with nothing. He then tried to recover his losses by patenting a new system which never took off.

The two systems have nothing to do with each other.

Incidentally, those spikes you see in the photo reach deep into the ground. They had to drill holes for them before they could be inserted according to some new information I just received.

I have to re-think the entire system in light of these new revelations. I wish someone could gain access to Stubblefield's papers. There is a whole trunk full of this stuff In the university archives. There is also some museum there where they keep stuff. I wish someone would have a look. A bit far to go from Australia.

Hmm Hans,

looks like a job for a private-I to me!

Hans:

I was doing some surfing a while back and remember reading an article (which I will try to relocate) that said Stubblefield's son, the one in all the pictures with him, was still alive and living in TN.  This article was about 5 years old but, I will see if I can locate him.  Would that not be interesting to speak to his son?  He could possibly answer many questions, if he is alive and willing to do so that is.  I will look into this again.
