FM Microbug

FM Microbug
This bug circuit operates in the normal VHF FM band and can thus be received using any ordinary radio. The circuit based on a somewhat uncommon IC, the 74LS13, but with a bit of searching you can still manage to find one somewhere. The other five components (that’s all!) are all readily available. You might already have them in your parts drawer.
