Question about Cobra 148 GTL 120-Channels Base CB Radio

1 Answer

I have a Cobra 148 mounted on the hump in a pickup truck and it works fine. Then I plugged in a old Turner +3 desk microphone and I get bad feedback when it is keyed up and I can also hear my voice thru the speaker in the radio. If I move the microphone away from the radio and turn the volume down on the mic it isn't as bad.

You're most likely getting lots of RF feedback from the metal cab of your truck,combined with the real sensitive nature of the amplified Turner mike.I would put an old original Cobra (coffin mike) handheld mike or a Astatic Roadking 56 (RK56) on it.They are really hard to beat,especially when you have lots of feedback & squealing. I also have a 148GTL (malaysia made) that has a Turner +3 deskmike & it squeals in my truck but not in the house. The 148GTL has given me better service than ANY other radio I've owned.It has 120 channels (freeband) & upper & lower sideband. I think mine is a 5pin Cobra-type plug-in. Try a simpler mike & good luck. Squirrly

Tip

Enhance your audio transmit


i advice to use a Desk Microphone whenever at your Home or Office, it enhance and make your audio clearer and most of all louder, even if your Signal is weak , having a Loud and Clear audio will perform better than a strong signal with a Stock Audio. Monitoring stations will hear and be amazed with a small signal but a loud audio.

suggested mics like Turner plus two, Turner sidekick, and the famous Astatic Microphones

it can be also connected to Echo Chamber to provide nice effects.

most of all, the antenna, ..no matter what radio, the one with a good antenna performs better, than a setup with booster having poor antenna installation. typical SWR is 1,1 to 1.3, if you can get 1.5 its good but 1.0 is best. Good grounding is also important.

for Omni , i suggest a Golden Penetrator antenna , it is a 5/8 wavelenght Vertical Antenna ,

a 2 element Quad or a 3 element Yagi Antenna for directional one.

and a good Regulated Power Supply too, must have at least 6A minimum,

higher is better.

Sounds like you could have a bad soilder joint in the radio. If you hit the top or bottom of the radio does it help? If so its soilder. You match your antenna to your truck not the radio. You might want to recheck it.
