Part

C1 1n disk capacitor (102) 1 pc.
C2 5.6pF disk capacitor(562) 1 pc.
C3, C4 10 uF Elec. Capacitor(25-50v) 2 pcs.
C5 3-18 Trimmer Capacitor 1 pc.
R1 330 ohm 1/8 w Resistor 1 pc.
R2, R5, R6 4.7k 1/8 w Resistor 3 pc.
R3 10k 1/8 w Resistor 1 pc.
R4 100k 1/8w Resistor 1 pc.
Q1, Q2 2N2222 NPN Transistor 2 pcs.

it says "5-6 turns of .5 dia wire" what measurement is .5?

gauge/thickness/diameter

matstermind in reply to kd8iktNov 18, 2011. 4:16 AM

i meant is it in milimeters, or other type of measurement

i think im on the wrong page/thread http://www.instructables.com/id/Making-a-simple-spybug/

i have no idea what frequency this broadcasts at. is this just supposed to be obvious? i'm going to assume 100 MHz until you say something else. Hmm, that doesn't work. there are a lot of frequencies out there...

No sorry try around 88-94mhz

wow, now I can do surveillance on beehard44 (lol, pun intended)

this is supposed to be our communications in sierra charlie hotel *CENSORED CENSORED* lima, riiight?

uuh, roger that hotel-bravo-four-four. you forgot to mention we needed 2 coils, or did you make another version?over. (all pun intended)

cliffyd (author) in reply to nutsandbolts_64Dec 15, 2010. 4:17 AM

uhhhh # 10 says 2 coils, is that what you mean?

Oh, I didn't see that there.... Now, all I have to do is get that other ceramic capacitor that messed up my circuit and put it where it belongs... then solder.... I should have breadboarded it before I began soldering. Thanks for the correction.
