mobile cb radio

Does anyone know if ham/mobile/CB radio operators have the capabilities to eavesdrop on wireless and/or landline telephone conversations? If so, would it be possible to zero in on a specific, wireless home phone, by address or position instead of by number. We have a civil lawsuit pending...Based on some odd information that was exposed during previous negotiations; I suspect some "funny business" is going on. It just so happens, that the defendant in this case, is a "radio head" with a top-of-the-line base and 4 mobile units. If this, in fact happening...not just paranoia, what (if anything) can be done to counter or stop such an activity?

Yes with certain radios a ham user can listen in on phone conversations, however if that person was ever caught the FCC would more and likely revoke the users license, and stick them with several hundreds of dollars in fines.

CB base station and antenna put together from a mobile CB, a 102quot; SST whip antenna, and some CB shop / hardware store items. My experiences ...

It only came with a power cable that goes into a car radio and I do not have a car. Is there an adapter that can be used to plug it into a socket at my house? I would like names/links please!

You just need a good solid 12v power supply. You can find them on ebay like these

or at most ham radio stores, cb stores, or even Radio Shack.
or even Hobby Lobby

or for a whole list of "ham stores"

can I use my mobile cb radio as a base?
if so what would I need?

The best idea is to go buy a proper regulated and filtered power supply made for this job.

They aren't as expensive than you think and are well worth it when you consider it has protection circuits for over voltage and filters to provide a clean voltage output.

While the radio was design for car battery power , a suitable power supply will do the job just as well.

Forget about the idea of using car battery chargers.
These are unregulated and pass a lot of noise through the supply to the radio.
everyone will complain about AC hum in your signal.

Go to the shop (or ebay) and buy the correct CB radio power supply.

As far as antennas are concerned , you can use (with modifications) a car CB antenna , but if your wanting the best performance (and distance) go buy a proper home base antenna.

They are a bit expensive , but you will get at least 3 or 4 times the distance from your signal compared to using a mobile whip.

I have been troubleshooting this problem for months...

I have mobile Cobra 18WX-ST-II CB Radio hooked up to a 4-foot Firestik no-ground-plane antenna. I get crystal-clear reception from people miles down the road, but when I transmit, people tell me to, "throw that CB out the window" because all it does it squeal like crazy. Plus, the TX transmit bar goes all the way into the red while transmitting.

I have the no-ground-plane antenna because my car is a 2005 Saturn Ion III, and is predominantly coverd in plastic. The antenna is mounted high on the trunk area of the driver's side, and it is insulated from the car. The coax runs through the trunk and along the floor of the inside of the cabin, up to the CB radio, which is hooked to the bottom of the dashboard of my car. The wire is not pinched in any way, nor is it cross. The connection is solid at both ends. I have tried tuning the end of the firestik, and I have tried grounding it directly to the negative terminal on the battery, even though it's a no-ground-plane necessary rig.

The CB Radio is power through the cigarette lighter with clean, solid connections.I am not picking up RF interference because I have tried the CB radio with the car shut off.

The CB is stock, the radio coax is unchanged, the antenna is unobstructed...

Please, for the love of God, can anyone give me some ideas? Do I perhaps need to find a way to ground the actual CB Radio metal box to the chassis? And if so, how? Could the position of the antenna be poor? Could I have not made solid ground connections even though it's a no-ground-plane rig?

Thank you.

First of all if the antenna is truly a "no ground" antenna, remove the wire from the negative post of the battery. There are two possiblities why it is squealing. You may be talking too close to the mic. Or if the radio came with the stock mic, the mic could be bad. See if you would be able to borrow someone else's mic for a test. Hold the mic about 4 inches away from your mouth when speaking. If your radio has a mic gain. Set the mic gain to the middle. The mic gain is like a internal power mic. If the mic gain is too high and you are talking too close to the mic, you may be over modulating (squealing) on the air. Even though it is a Saturn. I think that you would be able to get a trunk lip mount with a 3/8 x24 screw in antenna mount. When the antenna is mounted to the trunk lip (using the allen screws) it technically will be grounded. Best of luck.
