The Cobra 29 has been the top of the line Cobra AM CB mobile for many years. This radio delivers more modulation swing than the Cobra 148 GTL. Many operator thought they were able to get more power from the 148 because it cost more money and had sideband. On the contrary, because the 148 has sideband, a compromise was made. The audio transformer that delivers the higher voltage to the final and driver stage of the 29 isn't used in the 148. I've seen 20 to 23 Watts peak out of a Cobra 29, were the 148 is capable of 16 to 18 Watts peak. There have been rare cases of a couple Watts more out of these radios, but this is in 1 out of 200 radios. The Cobra 29 is capable of delivering 28 to 30 Watts of peak and 8 Watts of carrier power by changing the final transistor to a 2SC1969 and adding some capacitance and tuning. One area that the 148 GTL excels over the 29 is in the receiver. The selectivity and noise reduction is better in the 148. But they are both very good receivers.There are tricks to lower the carrier of the Cobra 29 transmitter while keeping the modulation swing almost to maximum. Say you have a amplifier that requires 25 Watts peak input to deliver full peak output power, but you only want a 2 Watt dead carrier. First the final output transistor must be changed to the 2SC1969. Then the JP-36 jumper is removed. Add a 50 to 200 Ohm resistor and a 220 MFD 16 volt capacitor in the JP-36 location. See the schematic below for the resistor and capacitor location. This Info, Was Very Helpful To Me. Wanted To Share. Read full review

Skywalker Radio has increased power, keying the (tuned to radio) Ranger Mike makes a power hum. Clear and crisp. Skips easily Boston to Detroit with correct conditions. Boston Locally, reach 3-5 mile area (congested) Wish more people locally into c.b. radios like the 1970s. Using a lighter plug power cord and a Lil Wil Antenna, calibrating to a 1.25+/-

Radio works like it should, sounds great. These radio's are great for night time driving, complete face lights up green, perfect for viewing. Great receive and transmit, getting good reports from other cber's. Don't let the REFURBISHED title scare you, it's all checked out by Cobra, works exactly like it was new, from factory!

Arrived on time as usual . I hook it up in my semi truck and it is working great . I have been told it sounds better than the last couple that I put in there . Sound on my end is also better .

I have this tuned to my predator 10k 1-17, I was talking to a trucker 35 miles away the other day, he could hear me crystal clear, radio also receives very well, it makes a huge difference having a super tuned radio
