Hard to believe this thread is still alive after 8 years! Its been some time since I had to un-whack a radio, so I guess its probably been some time since he's whacked one. I CAN say that whackpack 2 wasn't really "different" than 1.

I've run the new SL41 for a little while now on my shop radio, and I've gotten nothing but good reports from it. I'm pleased with its construction, and the tone quality. It is obvious that a lot of thought went into this microphone! I, too, look forward to seeing what the reincarnated Palomar...

I'll chime in with my thoughts. I liked the original 497 a lot better than this new version, for one main reason - the AMC control POT is unbelievably hard to set just right. Its almost as if the proper POT value was multiplied by twenty, leaving a tiny little window the size of half a hair...

Agreed. I make it a point to make sure it won't pull more than 40 amps on SSB with HARD modulation. One of the things I do is make sure the main amp bias's are set for no more than 4 volts (make sure the bias level for each quad is within .1 volts of the other, as well)

I don't generally have that problem (low AM modulation) with the 636, with a very few exceptions (the new Uniden 680/880/980 radios). I find that if the radio is properly tuned, the 636 works well. I do run into the odd instance where teh customer's voice just doesn't go well with the 636 for...

I didn't even bother to read all the replies, just going to add my quick 2 cents. For transfomer-modulated radios, you will generally be limited to the 4:1 ratio, since there's no practical way (that I know of anyway) to add negative peak compression to a transformer-modulated radio...

Another nice application of external digital control to a PLL chip! I first used the printer port from a computer to do that: www.dtbradio.com/cbcomp.html. My first prototype used DOS-based software and had a scanner function. I later wrote Windows software that dropped the scanner and added...

I agree that the 8v problem is the priority. WHat I would do it remove all load from the output of the 8-v regulatr, and then reload it with a 1k-ohm resistor only. Then check for 8v. If still low, then replace the zener and small C945 transistor nearby. I've seen both fail on occasion.

My choice for size would be the 510 with a good quality echo mic. I probably wouldn't even bother tuning the radio, since it won't tune much higher than stock anyway Turn the internal output level of the mic up to around 30-60 percent, set the echo, and people will think you're running a...

If you are using the factory mount (which actually has decent ground), you don't need a long-shaft antenna. 10K's are very good antennas, but over-priced in my opinion. The Tram Big-Cat series test about the same, as do the Road Ranger antennas (Road Ranger out-did the 10K in at least one test...

Stand to close to this when its running and your internal organs will be too fried for you to piss.

I have to disagree. About 15 - 20 years ago, I ran a DX350 mobile as a base unit, using an RV power supply at about 14.5 volts. One day I was talkign along and noticed I was showing quite a bit more output than usual. I didnt think anything of it other than "cool!!", and kept on talking. After a...

Be suspicious of 2SC2999's that are currently available. I've been the victim of a couple bad batches. It seems like the original parts are being replaced by cheap copies that aren't as good. Can't say that's the case for all sources. As for your continuing problems, the functioning PA ruled...

I was just made aware of an Ebay listing for the Cobra 29 LX which is a verbatim copy of my own listing (with the exception of the price - this guy is claiming to sell the 29 LX for $39). The listing in question is located at Cobra 29 LX 40 Channel CB Radio | eBay. The listing from which this is...

He goes by Roberto Renta, and Cielo Renta. Known email address is crenta@aol.com. His shipping address is in East Elmhurst, NJ. He comes off as a big spender, but in the long run, he's cost me a heck of a lot more than he's spent, in the form of lost potential customers and lost revenue, etc...

So far these seem to be genuine Jackson boards all the way, right down to some of the part manufacturers that have been gone for years. I agree on the screws. I've been replacing the ones I find stripped, but I'm going to have to start replacing all of them. I apparently dropped the ball...

Not sure what anyone else is seeing, but I'm noticing that almost every one of these out of the box has loose/stripped screws or screw holes.

Thanks for the flowers, I appreciate it!

My price does include conversion, tuning, and frequency alignment.

Long shot here, but if you're mounting the radio in a bracket and tightening the mount knobs way down, it could be pulling the audio chip away from the circuit board. Problem with that theory is that the receive audio would be gone, as well, and you stated that you still had good receive. Only...
