led light comes on when Amp is keyed.

This is the place to ask questions about linear amplifiers, or power supplies

led light comes on when Amp is keyed.

here is a question. I have an LED light hooked on a boom and sometimes when I put the heater on the lights will come on unintentionally. Any ideas?

have you ever touched a led light to an antenna while transmitting. It will light up. so maybe its just stray RF

You can take a 4' florescent light bulb (just the bulb!) and hold it in your hand a foot or so from your antenna, Key your Mic, and the bulb will light up!

Stronger your Amp, the farther away from the antenna you can take the bulb and it still be lit-up.

Next thing you may want to think about...Is if stray RF can light up a light bulb...wonder what it's doing to your brain cells? :whistle:

LED's inherently are susceptible to RF and it doesn't take much to light them up. I used to place them in my swr/watt meters to act like a modulation lamp. Wait til you get some wattage in your vehicle and see what all lights up. I remember having a pickup with a bed cap in front of me one day, was blinking the marker lights and interior bed lamp, the guy couldn't figure out what was going on,, lol.

There was a time when guys would tape a Led light to the tip of their mobile antenna so when they keyed up it would light up

Use to use shrink-wrap and attach them to the end of the stinger...Problem with that is, no more annoying other drivers around you by playing "CB Rambo or playing music" since your easily spotted when the antenna lights up! :lol:

Back in the day you could get a couple led's and some shrink tube. Place a piece of shrink tube on the tip of the antenna so as not to short out the leads on the led, not necessary if the antenna has a coating or shielded. Then place the led('s) to the tip with the emitter above the tip, another piece of shrink tube on the leads to secure them to the antenna.. Have at it, best seen at night,, lol,, think that is a given.

BTW, back in the day I think this cost maybe 50 cents to make but they sold them at **Non Sponsor** shops for like $10, heck of a profit don't ya think.

Well, thank you all for the informative, as well as entertaining, positive responses.
That is an issue being understood now and not one to concern much with.
I'll move the light.
