DAY1'S PRESELECTOR
Although I am in possession of a preselettore in kit form to be assembled again , I'm always looking for new items that can enhance the station, regardless of what the market offers !
It all begins on a Sunday morning at a flea market, where for 25 Euros in my pocket I put a variometer, with whom I immediately thought to an antenna tuner for reception only, because five minutes before I had bought a book with a scheme of a preselector.
After the usual inspirational chat Enrico I2BGL, suggests building a primitive version of the preselector, an inductor in series with a capacitor, said that, so i use my selective voltmeter with which I made the first experiments listening using the G5RV antenna.
The results obtained are very encouraging, in the spectrum of Hf, 15/20 dB of gain on the voltmeter see them easily, in its primitive form you see here at the bottom, now I just have to find a suitable box to finish it.
Primitive form of primitive preselector !
