Take your radio to a CB Shop and have them 'tune it up' or 'peak' it. It is usually a modest fee and will improve the transmit range of the radio. There are usually shops near truck stops, just ask around on channel 19 in the area if there is a shop nearby.

Some radios do better than others, there may not be a great improvement on your particular radio.

How to adjust cb for linear amp installation


That is a broad question. It depend more on your choice of amp. Typical setup cobra 29 with 2 watt dead key or carrier into 150 watt amp. We must pay attention to the total swing a more powerfully radio could still hurt this size amp if the pep wattage was to hi no matter the dead key being low. The cobra is no threat to this size amp as long as dead key is reduced.

Can i use a 10 amp power supply run my cobra 29 and 100 watt linear


I will answer the question. Figuring that 10 amps is continuous not peak. 10 amp multiplied by 12.5 it should be good for 125 watts. But you are on the ragged edge. I do agree you should lower dreaded key but you did not ask that question. But a swing kit will solve that. That is amusing SSB and the 80 watt cobra 29 comments.

Cobra 29 Lx turn power up


one of the few radios that won't allow you to turn up. the most you will get is 4.5 watts . if you want power buy yourself a 250 watt liner amp and leave the radio where it is . turn VR 4 up for max modulation and go for it.

Is it possible to convert the cobra 29 wx nw st sound tracker cb to 10 meter amateur band?


No it cannot. If you want that buy a Ranger or a Galaxy.

The 29 can be altered to increase modulation and turned down in power to match it to amp for increased output of power.

Set to dead key a watt or so with a 100 watt amp it would dead key low and swing to 80 to 100 watts pep.(peak envelope power)

Cobra 19dx iv when i key up it swings all the way to a 9 is there any way to set swr,s without a meter


Just buy a factory built antenna/(it should be close) Buy you a magnet mount RADIO SHACK job(works). If your indoors buy ANTRON A99(set at 1.3 SWR factory). If it keys 9 db then that equals 4 watts output thats OK.

My cobra 29 has a 75watt amp on the back how can i get more


If you're using the RFX-75 amp section. Then you'll need to make sure your transmiter section is tuned for full output. The last last unit I installed in a Cobra 29 LTD, the radio modulated right at 100 watts output.
Hope this helps,
J.R.

How do you tune and peak a cobra 29 ltd classic and how many watts will it put out after it is tunned and peaked


i would highly suggest you take it to a cb shop to get a cb tuned and peaked. before you do that though, make sure you have a good antenna system. a good antenna will have a much greater effect on your cb than tuning and peaking. as far as output, who knows? it all depends on the skill of the person doing the tuning. be warned that any output over 4 watts is illegal and you could recieve hefty fines if caught with an illegal radio.

Question about my cobra 200


no need to increase power output. you can take a radio with 100 watts and a radio with 10 watts that had had a modulation kit installed and the 10 watt radio will out talk the 100 watt radio ALL day long. the best thing to do would to put a mod kit in it and have the dead key cut back to 1/2 watt then put as little amp behind it. with those mods it will be loud and clear. hope that helps
