Effects of homemade MW ferrite loop stick antenna (Built-in pre-selector amplifier)

This time, I tried making a MW ferrite loop stick antenna by applying the preamplifier introduced in a previous video.
The shooting location was inside a reinforced concrete building, but the reception was very good thanks to the large ferrite bar antenna.
The SONY TR-8060 is an old transistor radio, but the unused timer terminal has been modified into an antenna terminal so that an external antenna can be connected.
The TR-8060 is originally a high-sensitivity medium-wave only radio, so it can take full advantage of the benefits of an external antenna.
What you have to be careful about is that if you place the radio and antenna too close, it will saturate, so in that case you will need to widen the distance between the radio and antenna.
