- This is a mod I came up with to turn internal accessories on an off without mounting a switch or loosing a function of the radio's buttons. Its in a cobra 29 lxle but can work in any radio.
29 LTD Knock off radio I have never seen one like that ...... I have been out of the 2 way radio repair for 25 years , I am thinking about getting back into it.......
😊
I rewatched it and I figured out how it's done ...... ....I forgot about about this video , someone replied to my 1st comment with an emoji , I got a email saying somebody replied to my comment ..... BTW I did build a new workbench temporary until I convert the front foyer of my house into my new shop and office , found some some great test equipment on sale and built a few things myself , ordered a but load of parts , and I am open for bizness ......
When my ignition switch broke on my aging Jeep, I made an ignition switch using the exact same method. I just place a magnet in the coin tray. Close the coin tray, and push a button. It really fascinates people the first they ride with me.
inside of the radio he got a magnet switch and outside using little magnet inside a little button
Nice hombrew. Physical pull magnetic altered relay switching system. Genius
I use to do that with a reed switch and no one could turn my computer on lol. The only way to turn it on was to hold a magnet over where i put the reed switch in the case, really messed with people's mind because they didn't know i had a magnet in my hand. Same principle he is using here.
Great method to use :)
That is pretty kewl.
I am going to try this method while driving thru a construction zone so I can make that cool noise .
a pretty awesome idea . I never thought of that. as an auto mechanic I'm going to see if that will work for testing relay functions in automobiles without having to pull the relays ..
it probably won't due to the proximity of the plate inside the relay but nevertheless an awesome idea for radio ..73 to you brother #104 Devon Pennsylvania
magnetic switch, thats a great idea, you can use a little magnet instead of that knob so it will look cleaner, slide the magnet to the side to turn it off
Why would you want to slide it off? Some people like to keep their radios scratch free! This makes it easy to pop off! We take care of them
Yep....I did that before you were born.....ole magnet trick
Its a magnetic switch. Wont work to well driving down the road. But its a cool idea
its clearly a magnet
magnet for sure Dead give away was how you handled the button It was behaving like a magnet Got us going though Well done
also be careful with magnets on or close to radios some of the IC chips dont like them it can damage them
It's a magnetic switch ! Anybody can figure out that your using a magnetic switch
Hey that is a slick little trick. Wonder if it would work for some extra channel switches.
+Mike S Absolutly.. It will work for all sorts of things. It is simple off and on. When the magnet is near the read switch the circuit is closed. When it is not there it is open.
That's a petty good idea, just don't loose the knob, if you're in a truck things tend to move quite a lot lol.
originally I was going to use a chess peice but the knob was handy. it's a neodymium magnet so it doesn't move.
I love mine SR-497! I bought mine from skytronics :)
7 years later the secret is long gone
Video should be called guy thinks he invented the magnet switch 🤣
U can reprogram EPROMs from the display and add something very special in the menu such roger beep or extra channels, but of course we are not in Japan....
been there done that the only trouble i found with using reed switches with radios RF is some times they fail with the close rf energy fields
And your point is ?
knob is a magnet ?
hall effect switch in the radio and a magnet in the knob, but what if you eventually permanately magnitize the cover in that one spot, oh well time to start winding yourself an old fashioned degause coil i guess, lol
@dr07828 I like that key-up. What is it?
roger mathers it's just a cool sound effect I found online it's on a pp1
Very cool, didn't know a pp1 could be used for keyup. I assume a relay is needed
roger mathers no. a pp1 is negitive triggered so connecting it to the cold side of the ppt will trigger it as soon as you key up the mic.
I see, thanks
damn.... people are mad over your magnetic switch. lol lol lol
stil pretty fuckin cool
or you could keep the knob in its place and place a thin black strip magnet on top
No. That won't work. The magnet has to be very strong because of the thick metal casing on it. A normal strip mag would not do it. I had to use 2 neodinum magnets together and it just enough to trip it.
It's just a magnetic switch
Watch how he picks the knob up mag in it
cool
my first thought was that you were having to use some force to move your knob on and off the radio. You are using a rare earth magnet. I am amazed that you tried so hard to show that the 3 different ways to key up the mod was showing that a simple metal knob would do this when in place. The reed switch is inside the radio and is what causes the key up noise when the magnet is in place. A better video would show what and where you did this mod. Keeping it your secret is very childish.

Lol, I call B.S.!!! You Modded that Allen Wrench!
Really though, nice clean mod. Got to find me one of those modded Allen Wrenches...
actually your completely wrong. if you read the comments many people know how it is done. there is a reed switch right under the top cover. glued into the know is a neodinyum magnet which when put in the correct place turns on the pp1. so what you see is for real. and I have no clue what you mean by Allen wrench. ..
*snicker* I was playing around. The Allen Wrench or Allen Key is the tool he used to short the two mic pins. (They are primarily used for loosening or tightening hex head bolts) There is absolutely no way you could mod an Allen Key of that size to make a sound like that, which is why I thought it was funny.
Yes, I understand what a Reed Switch is and how they work. Sorry for the misunderstanding.
+Donald Reiman
The Allen wrench must be left in place in order to complete the Gamma Ramma Lamma Bee Bop match. Thus, the tuned circuit may employ capacitive reluctance, rather than Non-sinusoidial mode filtering techniques, which
can cause phase shifting and side fumbling in the 27MHz range.
I modded my allen wrench to my Alan wrench
Nosedive4130 ... no silly not only that but it's gotta be a left-handed Allen Ranch as well but you have to make sure the end is cleaned properly with a fallopian tube ..Lol... MAN SOME PEOPLE ARE TOO FUNNY
they make pots with push button on off...
i use the same radio in utica ny.
Your pretty stupid.... Of course it is a magnet. If you could read you would see that it has already been said many times by viewers that this is a reed switch. Which is activated by a magnet. Turd Wrangler..
Just ridiculous. Eventually will mar the cover with extended use. To easy to drop magnet knob between console and seat, etc. Look you have a dynamike, rf gain and delta tune control that can be replaced with controls that have dpdt push pull switch on them. Will not affect original control settings or functions. You can have noise toys, high/low power without extensive hidden menu access, channel crystal switched in or out, rx preamp, FM board, BFO, etc. Nothing to lose or mar radio. Original knobs also. Completely hidden.
Why show the magnet trick if u r not going to show people unreal

Reed switch
Magnet switch
Yes, but up until at least the point I put the vid up, I hadn't seen anyone do this. I still haven't.
@@dr07828 pretty damn cool that you incorporated the magnet switch into your radio
& I can never get back the 3 minutes I wasted here!!! SMH
This is nothing new. Electronics 101...and real amateur radio operators and technincians have been using reed switches and magnets for various projects for decades.
As is described in the title, have you ever seen a cobra 29 with this mod?
typical cber. no wonder they call it Childrens Band.
Nah nah nah I'm not tellin. Really?
Learned nothing and got no enjoyment from watching. Time wasted.
To me it sounds annoying
