A factor to be taken into account when deciding whether to have shorted turns or an open coil is the possible corona discharge from an open end. This will also introduce losses. For a fixed station (
In an attempt to gain some insight on the behaviour of coils with shorted turns I tried the mathematical way and this is what I found (hope it is correct...): Said L1 = inductance of the first induct
Hi Martin In Peter Dodd's book LF experiments page 55 a drawing is shown of a loading coil arrangment. The the coil inductance is adjusted by shorting turns on the coil. Is this right? Yes. If you lo
Claudio just got a chance to look at what you offer with your calculator and it is very nice and easy to use and works well thank you Bob K3DJC http://www.qsl.net/in3otd/variodes.html
Regarding variometer design, I have put on my site a simple form that computes the main parameters for the classical two coils variometers, both the sliding and the rotating coils types. It is at htt
My experiance of shorted turns on recording heads and transformers is that form a low impedance short that effectivly kills the inductor. Hello Martin, In Peter Dodd's book LF experiments page 55 a d
