/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).

Nisam testirao bateriju niti domet u zgradi. Buba je poprilicno jaka pa ce se cuti bilo gdje u zgradi, garant. Jos nesto, na shemi je potrebno zamjeniti mjesta onim dviju zavojnicama. Pogresno sam im naznacio vrijednosti - naopako :)
