Step 5: Put on the Clip

Lay a small paper clip or another small object on top of the talk button. The masking tape will protect it from being damaged by the paper clip.

Step 6: Keep Wrapping

Continue to wrap the walkie talkie with masking tape, covering the talk button. This will keep the talk button on.

Step 7: Hide It

Hide the walkie talkie with the masking tape around it in a room where you want to spy and listen in on its occupant's conversation.

Step 8: Leave the Room

Go into a separate location when no one can hear your walkie talkie so that you can listen in on the conversation in private.

Step 9: Listen In

What's the paper clip for ?

kivster (author)2012-02-11

Well you can listen in but until the battery dies i would give it a larger battery to let it last longer

wonder_yosemite (author)2011-12-11

And lets not forget that when batteries run low the dam walkie-talke lets out a beep ,indicating low your screwed.

Or you can buy 2 cheap tracfones, call one, hide the other one and then you can listen from miles and miles away.  Just hope you dont hit a bad service area.  :)

Many radios have a built-in voice activated transmit option.

You needed nine steps to say "tape a paperclip to a walkie-talkie and leave in another room"?

ReCreate (author)CameronSS2009-05-16

Yeah,Its pathetic right?

codongolev (author)ReCreate2009-08-21

am I going to have to flag this as "not nice"? because it doesn't really sound like a compliment.

hiya, am not a professional HAM radio operator, but one thing i learned with working with radios...if you keep the PTT Push to Talk) depressed for a long time, you could end up burning up your Finals.. am not sure if this goes the same for Family Radio System (FRS)..thanks!!

Now if they were going to do a hit, the ending would be different...for some.

Rye2121 (author)macca4life2008-10-10

Rock Soldier (author)2009-06-25

ac1D (author)2008-07-28

What do you mean?

grundisimo (author)2009-05-06

batman96 (author)2008-12-29

goto dollar tree and buy a 1$ (duh) listening device and get a long extender audio cable and tada you are done

1nv3nt3r (author)2008-11-08

This was in one of the evil genius books but the design also incorporated a sensitive audio preamp.

Lithium Rain (author)2008-08-20

Cool, I'd like an ible on how to do this with cell phones and connect it to the computer via USB with bare wires, like in burn notice!

psi3000 (author)2008-08-06

Nice quick idea. You could also solder a jumper on the PTT button and put a pre-amp to the mic to help pick up the lower voices.

fegundez1 (author)2008-07-29

use the vox feature and the walkie talkie should auto send by voice instead of having to hold down the talk button
