Improving the ATS 20+ reception in small space

Подробнее о видео

The first antenna system is a Ferrite setup connected to a RF amplifier by inductance. That system works as a very narrow Bandpass Filter. It also allowed me to cancel or significantly reduce unwanted noise sources nearby my location. The RF amplifier works from 150 kHz 30 MHz. I think it was a good approach to listen in low frequencies with ATS-20+, where the original front-end is not suitable for this kind of listening.
On commercial receivers, this antenna should be used close to the radio (in parallel with the internal receiver's ferrite antenna). In this video, I use an RF amplifier. The connection to the ferrite antenna is by induction.


It is a regular ferrite antenna (10 ferrite rods into the PVC tube, coil, and capacitor setup). I do not have the details about inductance a capacitance. But I know that the capacitor is a regular capacitor used in old radios. I think it is easy to build (no big mystery).


The second antenna is my homebrew Magnetic Loop antenna working at 11.780 kHz. I am comparing the reception between the original ATS-20+ telescopic antenna and my homebrew Magnetic Loop antenna. The RNA station was very weak currently (transmitting at 11,780 kHz). It was not possible to receive with the telescopic antenna. However, with magnetic loop antenna it was possible. See the video.
