Extremely high swr

3 Upvotes

So this is a continuation of my post. I bought an swr meter after I adjust to set switch to ref and meddle jumps right to the set line. Pegs the needle. Put the radio in another truck I know is good light goes out radio works fine put back in my truck ant. Light comes on I tried new coax hooked meter up pegs the needle. Swapped antennas with the other truck pegs the needle. Replaced the so239 studs no change checked mirror brackets for a good ground they have like .01 in resistance so that’s good. What am I missing?

Ticked off an Amateur

91 Upvotes

Had to go out for a bit to meet up with some friends. We decided to meet on a local mountain top and as we all talked, we were using my radio to talk to some other CB operators about 70 miles away. A local Amateur radio guy shows up, and the dumb ass parked less than a hundred feet away from us. He then informs me I am causing spurious emissions (bleed over) on his radio. I politely said No Sh*t Sherlock. He came over looked at my system (he did not get in my truck) and told me to shut it down or he was calling the police and FCC. Police didn't come but the park rangers did (the mountain is part of the national park system). Park ranger told him I had every right to be there and that if he wanted to report me to the FCC that that was his prerogative to do so. They refused to give him my info saying something about privacy. The guy took some pictures got my tag number and stormed off.

I am going to assume he will make a report and if the FCC does come looking, I will welcome them check the system. What I was using tonight was an out of the box stock Uniden Bearcat 980 with one of my & foot tall Skip Shooter antennas.

BTW I was reading posts earlier and people were talking about the 980 so I took it off the closet shelf and took it on my little greet and meet.

Back in the 70's I got two visits from the FCC and passed their inspections and once in the 80's Got caught with a modified Uniden PC66 putting out 1.5 watts. You guessed it even though modified I passed

Question Magnet replacement

4 Upvotes

Running a Uniden PC78LTX with Wilson 1000 whip roof mounted with magnetic base. Knocked the antenna to the ground when placing a ladder on the truck. The plastic protector came off and the magnet itself shattered and fell from the base. Can I just replace the magnet or do I have to get a whole new antenna kit? Roof mount is my only option. Suggestions?

Trying to interface RBI-1 keying buffer interface direct to Texas Star 350HDV

2 Upvotes

Good morning- tech question here have looked online on hooking the RBI 1 direct to the keying circuit located on the backside of the Texas Star but couldn't figure out the specifics on it. I allready have the custom RCA jack installed and ran the negative to the main black wire where it's soldered directly to the main board. Net has given very conflicting info on this some say remove the keying transistor that came with the original unit some say don't. Then some say solder to the emitter of the key trans some say the base and some.... Yeah the collector!? Then I also am wondering if you soldered the hot to one of the trans legs then r ya supposed to leave any of the 3 legs detached from the board or what cuz man, I've been down every rabbit hole with this & could use some solid advice plz? I was able to get the meter light to light up when keyed but no modulation is swinging on the meter when I key the mic and speak using mainly SSB voice. I thank any1 in advance for any helpful advice and again good morn. 459 East Central Missouri-operator Adam

Question Title: 1995 Pontiac Trans Am CB radio SWR is 3 with engine off and 5 with engine running — need help diagnosing it

5 Upvotes

I have a 1995 Pontiac Trans Am with a 4-foot ProStick CB antenna. The antenna runs through the factory radio antenna hole and is mounted on a custom bracket clamped to the factory spare tire bracket near the rear quarter panel.

My SWR readings are:

• Channel 1: approximately 3.1

• Channel 40: approximately 3.0

• Engine OFF: approximately 3:1

• Engine RUNNING: approximately 5:1

Channels 1 and 40 read almost identically. The mounting brackets are clean, bare metal, tightly clamped together, and have no rust.

I’ve been fighting this for months and can’t figure out what’s wrong.

What should I test first? Could this be a coax cable or connector issue, an RF grounding/ground-plane problem with the mounting location, a faulty antenna, or something related to the engine’s electrical system?

The antenna is mounted to a steel bracket I made which is clamped to the spare tire bracket which I stripped the paint from, everything is brand new, the antenna comes out of the hole that the stock antenna came out of

I’m looking for specific diagnostic steps to identify the actual cause rather than randomly replacing parts. Any help is appreciated

High SWR on Mobile Setup (Suzuki Jimny)

Post image
7 Upvotes

I'm installing a CB rig on my Gen 4 Suzuki Jimny to get back into the hobby after a break.

To start off, I'm using a Thunderpole T-800 radio, with a Mini Orbiter antenna using a gutter mount.

I'm receiving other stations well, but have thus far been unable to make contact with anyone myself. Using a SWR meter, I can see I am transmitting around 3.2w, but my SWR is high (2.5-3.0) across all channels.

I'm unsure of how good a grounding contact I'm making with the gutter mount, or if perhaps my roof rack is causing problems.

I'll check ground continuity once I have a chance with a multimeter, but has anyone here used the Thunderpole branded gutter mount kit (https://www.thunderpole.co.uk/gutter-mounts/thunderpole-gutter-mount-kit.html) and can suggest best practise for grounding? The screw mounts are done up quite tight, and should have gone through to the bare metal (Jimny paint is incredibly thin).

Any insights would be greatly appreciated.

Potential purchase

So I posted here before asking about a radio that I didn’t know about and everyone said make sure anything I buy has side band. So I have the opportunity to purchase two of these Realistics and one Cobra for $75CDN.
Do I figure out which Realistic works the best and then flip the other one and the Cobra?

New to CB with a new mobile setup

Thumbnail

7 Upvotes

I just got the Retevis MB1 radio and its accompanying magnetic antenna installed in my 2023 F-150. As the truck has aluminum body panels, I am using an adhesive steel mount on the roof to allow for the magnetic antenna to be attached. Most of the radio traffic I am able to receive has heavy static and I can barely make out voices. This is on all channels, 1-40.

Do I need to modify my installation? Is the aluminum truck roof the problem? Am I simply out of range for clear reception?

Any help is appreciated. Thank you!

My rci x9 needs some tlc, and im wondering if I can get some work done to it. From what I was told on my last post, the receive noise is on par for the radio. Wondering if there's someone out there willing to try and address it and fix it?

Mounting a Stryker in a Kenworth

I just got a good deal on a Stryker and I'm curious if anyone has figured out how to mount it in the existing 2006+ tray, I currently have a Cobra but I'd like to put the Stryker in place of it and ist too wide. Just curious about possible workarounds

What's the problem with my setup?

10 Upvotes

I'm just trying to get into CB radio with some old gear gifted/I had laying around from my dad, the setup is made of an rci2950 from probably the 80's, 33 meters of coax 50 ohm from lemm (the big one, I don't remember the name), a Sirio signal keeper 1/4 wave and if needed a swr and power meter; my objective would be to DX at least in my country, possibly using just the radio (I have an amplifier but I don't plan on using it at least for now) but I can't get basically any signal, mostly static, some distorted talking masked by the noise and if I get good reception other stations don't seem to get me.

the antenna is mounted on a ladder and a pole, not that high but not too low compared to the position I would mount it (I plan on mounting it if I can get some good qso), swr is good, cables should be soldered good, why do I get nothing across all bands? (am, and usb).

I tried some ft8 listening but I can't get a lot, on ham bands I can read some traffic tho.

really any tips are welcome, for now my main worry is to be able to listen to something, also I should note that propagation should be decent, it's been a month so far, two weeks with this antenna

edit: I tried switching coax and radio (another old one), still nothing

Antenna light on cobra 29.

7 Upvotes

Ever since truck cab was repainted and interior put back now my antenna light is on when mics keyed. It has new coaxial and new Wilson 2000 antennas. I tried radio in another truck and it’s fine tried deferent radio in truck that light comes on. Tried different coaxial same thing. Checked to make sure the plastic insulator is in properly on mirror brackets. What am I missing. I’m not real knowledgeable on the technical aspects but have always been able to solve problems. This one has me baffled on what has changed since repaint?

I found this almost new handheld during a move. It looks brand new and works well. I can’t pick up much of anything besides two guys bitching about life near me on channel 35 at night but it’s cool to have as a reminder of how life once was with a CB on the road.
