Post HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Reply with quote

Hi Ladies and Gentlemen:
I'm tired to try to build during last month A LOT of web's FM bug circuits (50-500 meters range).
And I promess to build one in order to gift a simplest FM electrect bug to my 14 years old nephew birthday.
I have in my component box some 2-10pf to 6-60pf trimmers values range, 2N2222, 2N2218, 2N3866, BF494, BF495 transistors, 74LS14 and HEF4011 TTL IC's, NPO capacitors and I need a REALIABLE AND TESTED FM BUG DIAGRAM THAT WORKS at 50-500 meters range.
It may be one or two transistors project and, if posssible, with resonant coil printed at PCB. Please, if anybody wish to help me I will be glad to mail him/her some Motorola MRF series (HF and VHF) hard-to-find power transistors.
Guilherme, PY4GIG.
