We found this circuit in documentation from National Semiconductor. For the medium wave range the coil consists of 50 + 50 turns of wire 28 in a ferrite rod.
A girator reverses the impedance of a signal. Thus, a low impedance signal at the input appears as high...
This circuit is from an old English publication from 1968. We can implement it with TIP32...
This circuit was obtained from a Popular Electronics of the 80's. It is set to a certain pulse...
