He is talking about Doug at Custom CB radios . He just did a stock black chrome cobra and it dead keyed just over 7 watts with a peak of 135 watts.

As far as his peak and tune. Yes he does a full alignment and tripple checks them to be sure they are perfectly on frequency. He does not clip or hack up a radio by cutting limiters here and there and other little tricks to make the radio "Look good" on a cheap watt meter.

There is only two techs I trust with my stuff. One is Al "owner of Sparkys CB shack" and Doug "custom CB radios and also former tech of Al's at Sparkies".

Also Doug is the originator of the Stealth Cobra. This is a Cobra 29 that has been done up and will do 40+ clean watts with crisp clean loud audio.

I have a first version stealth and it will walk right along side a Connex 3300 and will almost keep up with my Connex 4300HP in performance.

I am sending it in to get done up with his 3rd version upgrades along with the the RFX75

I would love to see a CB shop with a RF System analyzer to check the output and receive of the radio the proper way. I am not aware of many that have an extra 27,000 laying around in the budget to play with CB and charge 10 or 20 bucks to tune and align it. I know to do a proper alignment on a radio any radio no matter which one it takes between an hour and half to 3 hours depending on the complexity of the power supply and the amplification circuits and the PLL chip it has in it. It's not just tweek the power and check the Freq. You need to know all the other nice things like spurious emitions 4th and 5th harmonic reseinanse in the filter and chokes all those things plus more come into play for true alignment of a radio.

Did he really do a proper alignment? Must be some fancy CB shop you're talking about to be able to invest thousands of dollars in the type of equipment required to do this.
