This is a very nice - inexpensive but with good FM / AM Reception.
Assembled & Tested.
Module runs off 2 x AA Batteries.
(Headphones not included)
Product features:
1. Using high-quality PCB boards.
2. Easy to use, install two AA batteries - slide the power switch to select with FM (MHz) or AM (KHz) bands insert stereo headphones, and you can enjoy stereo FM programs and a lot of noise on the AM Band (probably).3. Tuning indicator LED - lights up red on strong signal source.
4. The DIY kit includes a wide variety of electronic components, which can be used to learn electronic circuits and cultivate hands-on skills. Although pre-built open to experimentation - even sliding in/out coil to change performance. Possibility of changing coil inductance (turns) as well as FM Crystal?
