(continued) You would think within the 102 to 108 MHz using the formula but it does at 5/8 wave range remember the higher the freq. the smaller the antenna pmr 466 perhaps, stay away from the Air-band unless you like prison food
Read the description the chloride is mentioned in there as for antenna length well have a bit of fun convert the output frequency of the bug to Meters wavelength = 300 / frequency in MHz this will give you the physical length of the antenna to a full wave then chop it down to a quarter wave and coil it to make it physically smaller but with the correct electrical length so say 106 MHz is about 2.83 meters divide by 4 is 0.707 etc I noticed he used 175cm which if we convert up does not fall with
2N3904, but according to original schematic found in ur "long range spy bug" video, it says only 2222 or 547 . these are like universal/popular items so u can use either
use the circuit diagram to make the transmitter using standard components rather than SMD (SMT) on a stripboard. Search "ck200 fm transmitter pdf " it's a very similar design.
sir dazaro, i saw ur both transistors are 2N3904, but according to original schematic found in ur "long range spy bug" video, it says only 2222 or 547 could be used. could u please confirm us about this issue, sir?
@riky22lou I can't believe no one answered you yet. The 2N3904, 2N2222, and BC547 are all NPN transistors that are functionally compatible. It shouldn't really make a difference which you use here.
@hasnain4000 I don't think it is possible to make a mobile phone by yourself, unless the Chinese make a kit to be assembled.
I usually buy electronics material from the electronics market in Mall (Maal?) road in Lahore. Its bettter to learn first. الیکٹرونکس کے لئے لاہور میں مال روڈ اچھا ہے
Very cool. I started making bugs about a year ago but never worked with smd components. How does someone tell between the capacitors, they are very similar by color code?
good job man

The lil tricks you used in your board making technique are really nice like the iron on and the lil wire for solution

I built one of these and left it in the interrogation room of my local police department. It was tons of fun until the battery died. :(
