I have an old Philips walkman that has AM/FM radio. I tried AM radio. Really I can get clearly 2 country radios. I caught very poorly 4 foreign radios or different countries, but they have lots of noise.
I plug in headphones with quite a long cable, and those headphones are plugged into the splitter that came with it, so that it can connect to headphones input and mic input since it's a complete headset. However this does not improve much the quality.
The frequency range in this walkman is from 530 to 1180 KHz I believe, since the lowest number says 53 and the highest number says 118 and below it says "10x". I guess it means you have to multiplay those numbers by 10 so that you have the KHz number.
The walkman doesn't have any external attached antenna, since I guess headphones do that function, however is that an easy way of improving the reception of AM signal? Is there a headphones cord optimal length?
