Kevin H: Idk maybe its just a spoof but the swr did read higher when i installed it in my old rigs works well with the new antennas though
Kevin Hendry: this actually helped reach farther but raised my swr I have to get a external meter to check it but haven't ran into much else via side effects
trooper3030: I bought on ebay a Cobra 29 LX CHR LE LCD CB Radio I didnt read the instructions on it before I bought it and it said .......... I purchassed the radio new and then sold it on ebay. The purchaser said the RF control was not working so, they returned the radio. I'm selling it "as is" ....... someone who can fix that issue will get a nice radio.
alizarin alexander: you'll be heard a lot farther away when your audio is like 120% modulation..I've been into cbs for over 35 years and you need at least 100% modulation on a radio or its gonna be in the mud...a radio with 100+ % modulation and 10 or 15 watts will get out much further than a radio with 70 % modulation even if it has a 300 watt linear...you can have a high carrier with low audio and get walked all over by someone with less watts but lots of modulation...you need modulation, more than anything else..i would rather have a setup with lots of audio and less watts over lots of watts and weak audio, anytime.
Jordan Hooper: Clip d11 in a cobra 29 as well for more modulation. This does distort the radio sound a little, but not enough to notice. Also, unscrew the insert in the pot toward the back of the radio (between the aluminum fins - unsure of its label letter/number). And as always, adjust using a good watt meter. Should get up to 20w this way. And if you're wanting more barefoot power, look into a Swing kit and IRF520 Mosfet mod. That'll get you closer to 40w.
Jeff Lummus: Adam Martin, what you suggest clipping, does exactly the same as turning the VRs wide open. Quit posting help in comments if the only things you can say anyone can find on the internet. you sir, have obviously never been in a radio with any of the proper equipment
greenstx: does this increase the watts and range of the radio or just make you sound louder
adam martin: and for cobra 25 clip d9..things the government dosent want us to know
adam martin: for cobra 29
adam martin: clip d11 diode to release the fcc wattage governer
Paraglidermx: No problem bro!!
bproudd: nice! thanks for the help! =)
Paraglidermx: The Dave swing mod,,find jumper jp32 lift right leg out,solder a 200 ohm resistor to it,,then run a wire from that to the front left leg of vr4,u may need to use more resistance to get the key down to where you want it 200 works good,make sure d11 is clipped or you will smoke T1 audio transformer.Now vr4 is a variable dead key pot that wont burn out like the jp36 mod,will swing 8 bird RMS all day long :)
bproudd: wait, so the wire that you remove to "clip your radio can be replaced with something else that boosts power, and how do you adjust your pots?
Paraglidermx: Beacause Im a new jersey hammer mobile.After all mods,that include bigger drive caps,2sc1969,dave made swing mod vari on VR4,trbx2 echo,key about 1 watt swingin 40 peak into my homebrew 5 pill with 711 2879s,,dude,,I run my mic gain about 12 oclock,,and slam hammer everybody,,loud and clear!!!
Brandon T Smith: why crank it, and clip D-11? why make your radio a splatter box that clips on an oscilloscope just to try to sound louder?
Brandon T Smith: for the love of god. if you know you should use a non conductive tool, TURN THE RADIO OFF AND UNPLUG IT!
Brandon T Smith: There isnt one on a Cobra 29. You find those on export radios with high and low power switches. For that you would need a cap/resistor mod. look it up on cbradiomagazine(dot)com.
Austin DeMarr: Thanks! Just got this radio today for Christmas! Was running a Cobra 19 Ultra III, so this aint my 1st rodeo :P
