Anyone help with bleeding

[w9cll]

Get rid of the amp?

Not sure about this hopefully someone can get me some insight the kids say when they have there Xbox on with their headsets i am coming through them really dont wanna add stuff to their headsets to try to stop it my radio seems to have a clear signal scope looks great is there anything i can do to stop it i know when putting the hammer down amplified speakers like computer speaker seem hard to stay out of i am also running a low pass filter behind my radio everything is also grounded anyone help me on this

I echo what everone else said.
1) A high properly tunned antenna.
2) Keep the radiated RF off the coax..choke, balun.
3) Stock radio, working low pass. Dont pinch da carrier.
4) Good RF connections...water,rust,Chicom made connectors..all bad.
5) Ferrite chokes at speakers and plug. Maybe a cheap UPS. Try a different plug.

You still maybe f@cked. Some cheap computer speakers are just crap. I remember a friend.who doesnt have a cb...called me once that he heard me comming over them as he drove by.

Discovered years ago that computer speakers powered from a separate DC supply bleed more easily than speakers with the AC power cord connected directly to the powered speaker.

Not sure why, but I discovered this entirely by accident with computer speakers here at the shop.

let's look at this on the bright side, at least you know the duck-plucker is working! Blowing Smoke Breaker! LoL

I appreciate all the help and suggested stuff the amplifier is a jb2000 i assumed it would be better than the d&a varmints or macos ive ran since going from sweep tubes to tranmitting tubes i think thats right? Now when u say rf choke at antenna i coiled coax a couple times at that point is that what u are talking about? I will have to figure out the ground loop i ran a rod outside put a ground block on the window seal and just ran wires to the cases from that i did also run a lowpass filter behind the radio i have never acually seen the radio on a scope myself wouldn't know what to look for anyway lol i do have a ham buddy who looks at signals while people are talking spectrum anilizer maybe? Said it looks good i just take pride of a clean sounding rig instead of some this is really bothering me if it messing with the kids xbox and computer speakers am i also getting the neighbors i gotta get it figured out possibly a bandpass filter?

The audio signal heard by another radio operator is NOT a gauge of a clean signal. Scope is ONLY one way; so is the spectrum analyzer. Some Ham operators do have the equipment to test you radio, so it could be helpful to find a Ham club in your area.

If you feed an amp with a signal that is full of harmonics from a nasty CB radio, it will amplify all of it. Which means that you would be contaminating the airwaves. Even a clean CB cannot legally run an amp. Ham operators are just as responsible for running a clean signal as anyone, but are licensed to use an amp if it meets specifications for harmonic distortions. It can be a pretty big deal, and you would be best served knowing that any Ham can turn in a CB operator to the FCC if they find your station location. The first warning from the FCC is just a warning - usually - to stop using an amp. They do not give second warnings.

JB 2000.
That is a lot of Amp.
How close is this guy to you?
As some one said before it might be tough to stay out of nearby electronics with that.

Yeah the JB2000 is a lot of horse power / steam, I know the fiberglass non ground plane antennas have interference problems at times, as compared to the metal 5/8 wave ground plane antennas. Yeah all the others said.

Good grounded radio
well tuned low SWR antenna
Torrid cores with the headset wires wrapped around them, and the power wires feeding the amplifier/speakers if there plugged into a speaker set. A call to these guys might help. See:

Seems most all RFI (Radio Interference) problems are all different and so are the fixes.
Good luck please let us know what the fix is.

RF choke at the antenna feedpoint. Likely common mode RFI so your coax is radiating as much RF as the antenna.

Huh. One of my rigs

If you have a low pass filter behind the radio...You should have one behind the amp.
Those JB2000 amps can get filthy dirty, especially if driven too hard.
Any of those I ever ran across if ran at more than 800 watts PEP output, will get the work all Toasters, TV's, Computers, and Heavens knows what else awards!!!
Most certainly if being used on AM, with a big swing radio.
The filters case should be run to ground buss also.
My worthless 2 cents

At 27/28 MHz, for example, an 8-foot piece of wire is about ¼ wavelength long.
It can have high voltage on one end and very little voltage on the other.
This means if your ground is not large enough size-wise and is longer than 8 feet to your first rod, your ground just became part of the antenna and can radiate as one!

Ferrite beads like the ones from Palomar Engineering should be placed between each piece of equipment to prevent ground loops.

Shouldn't need them. If you do it suggests a RF grounding problem that starts at the antenna.

 

[Shadetree Mechanic]

The ferrite beads are to prevent ground loops. If you have your equipment grounded to station ground and also connected with coax then you have ground loops. Why go through all the effort to ground the equipment only to make ground loops? The ferrite beads isolate the equipment so the station ground is also the RF ground. Many people get away with no ground at all but that doesn't mean it is correct.
