I went to a cb shob right off I 75 a few months back to get my little 29 peak and tuned. Paid the man 20 bucks and he took it to the back...came back a few minutes later..wouldn't bother with a radio check. It was a little bit louder but that's it. So a friend of mine suggested I take it to an old man he knows..we hooked it up it was only pushin 4 watts...1 watt dead key(wow now that's a big tune up...still at factory setting). Well he opened it up and the only thing he could find was they had clipped a wire and that it was causing it arc...as evident with the burn marks on my board..long story short he spent about 20 min going over everything and actually tuning it by turning screws and watching it key up on his meter. By the time he finished he had it pushin 40 watts...told me that's about all a cobra 29 would do barefoot. Got a radio check from a guy a few miles away...I feel like he did me right...even wound up buying an old general lee that buryed the needle from him...ill never go back to that other shop again...total ripoff
beware-dont let no cb shop start cutting stuff in ur radio!

I'd be leary of a shop that gets 40 watts from a Cobra 29 as well ... beware
flightwatch and KW Cajun Thank this. -

I talked to a guy on the radio in Boise, ID last night . Said he'd bought a Cobra 29 and paid a guy $150 to put bigger finals in it. He claimed it was pushing 100w because the guy showed him on his meter. Nobody could sway his mind that there was no way he was pushing 100w. He then proceeded to tell me that my Styker 497 sounded 'ok, but nothing to write home about.'
KW Cajun Thanks this. -
Those extra watts on a barefoot Cobra 29 are really harmonics. And they're most likely not going out on the frequency you're on, but rather adjacent frequencies.
I've heard of stories of Cb shops setting up the "happy meter" to lie to the customer. Or they'll just have a piece of coax connected to the antenna side of the meter, with the other end of the coax going into a hole in the wall and going into nothing.STexan Thanks this. -
Another trick unscrupulous shops used was tho turn the voltage up on their power supply.

It would be nice to have an expert you could count on and a way to really measure the increase in performance if there is any. We are depending upon what we "believe" as to any improvement. Installation can make a big difference in performance. Location of antenna on truck, type of truck can all affect the CB.

It is funny that people go to all the trouble to find ways to increase wattage by having some uneducated hack mess with their property when the manufacturer may have ten engineers working on the design, had more engineers look at it to make sure the design passes our regulations and then had it assembled by people who are supervised by more engineers to make sure that the quality is to a minimal standard for the price of the radio. Your little radio which puts out the legal limit has maybe 1000 years of engineering experience touching it from its design phase to when it gets boxed up to ship to the nearest shop, but still people trust those uneducated hacks to mess with it.
