/Schematics/Bugs/FM bug 420-480 MHz

How about getting that old Nokia phone out of your drawer and turning it into something freakishly cool? I will not lie to you, you will need a few tools and skills such as soldering/desoldering and making PCBs.

The range of this FM bug is around 1km with full CR2032 battery and good conditions. As the battery discharges the transmission range reduces as well as the oscillation frequency (VCO).

Nice work, but a poor frequency band for some parts of the world. Little chance the bug builder/placer/monitor will be discovered. A bit larger chance the bug itself will be discovered.

1km range at 420-480Mhz? I wouldn’t do that w/o a license. If you are receivable at 1km with a TV card you are probably receivable considerably farther by a ham with a decent base antenna from 430-450Mhz or worse yet by Police/Fire/Military/etc which use the rest of that band.
