At least us local guys have... www.kemnerenterprises.com/ A little pricey on some things, but I'd rather hand my cash over to a hard-working local guy than some massive corporation.

This one made me laugh. I've seen similar setups like this on several occasions. Someone decided to take advantage of an existing TV antenna and mast to mount their CB antenna to. But for some reason, they chose to mount the CB antenna 3 or 4 feet below the TV antenna. I'm sure that wasn't good for the SWR the radiation pattern, or TVI immunity........ Not a bad shot either taken from a 45 MPH moving car...... Holy cow, look closely and it appears that the TV antenna is mounted directly to that omni. Egads!

Hmmmm....... Honestly, it did appear to drop the sound of the noise, but the S-meter signal didn't seem to drop all that much, so I wonder how effective it really is... Couple better examples...

This is interesting, although from the product description, it would appear to null out noise in much the same way as Pete used to null out Cousin Brucie, via antenna phasing. But I can't see how it would be that effective with only a simple built-in whip antenna, nor how effective it would be on noise that is not from a specific direction. Still and all, it might be fun to play with on a base, but it would hardly be practical in a mobile when you are constantly shifting from one noise source to another. This reminds me of another throwback story. In the 1977 time frame, I came across a guy in Norristown, who was trying to come up with a way to reduce or eliminate bleed over. Back then there were so many local channel groups that those people in-town could be within blocks of other people who ran on a different channel. I forget the guy's handle, but he was trying to build an automatic electronically phased antenna system that would null out strong signals on nearby channels, thereby reducing bleedover. The theory sounded good, but I had many operational questions (like what happens if the direction you're talking in is also the direction where the bleedover is coming from?). I'm guessing that this guy either gave up on the idea, or he could not get it to work practically. I would think something like this would have to work with an antenna like a Super Scanner, only with many more tighter nulls. This video has a decent description of it's operation. No, probably not practical for mobile use in it's present form but maybe it could be built upon...

I won't go as far as to say that it CAN'T be done, but it's not something you can build a simple "Noise Blanker" circuit in hardware and remove it the way we currently do with pulse-type noise. The only possible way that I can think of to remove on-channel hash noise, would be to completely break down the receiver input signal in the digital domain, somehow identify and isolate the noise components from the desired signal components and digitally remove them, and then reconstruct the desired signal. Of course if the noise level is so high that it completely masks the signal, I'm not sure how you could do it with a wide bandwidth signal like AM or FM. But it would require high speed digital processing that would most likely exceed the cost of the radio it would be added to and it would likely distort the hell out of the signal. But if all you were concerned about is copyabilty and not rich audio fidelity, then it might be doable. Although that's above my pay grade. I was never much of a software geek.

With all these modern noise sources there's a golden opportunity for someone with the know-how to come up with a modern filtering solution. The problem is that the noise has to be removed at the source. There is no practical way to completely filter out random wideband noise at the receiver. DSP helps, but can't completely eliminate it... So it can't be done?

Makes me wonder what Alinco is up to with this move. Is this some sort of challenge, or is their version tough to crack like the old Radio Shack 10 meter rigs? Or maybe they have simply "jumped the shark". Interesting to say the least. My favorite feature? The fact that it's a DIN chassis (or close to) and will fit neatly into the dashboard of modern vehicles... Having a full featured radio that actually FITS inside one of today's cars is a definite plus for me. But my car doesn't have a DIN radio so it's back to the drawing board...... Yeah, the DIN size radios are a little late to the game, at least in the US, they've been around in Europe for a while. Most new cars have gone away from the DIN slots. Our new Mazda6 doesn't have one either.

The FCC has a list of "banned" radios which are not allowed to be imported. Any radio, which the commission finds can be easily modified, and appears to be primarily intended to be used by the 11 meter crowd, gets placed on the list. Having a "channelized" radio is one big flag right there. I doubt that this radio would pass the FCC's smell test for disguise 11 meter rigs. That being said, I never agreed with the concept of limiting sales to only licensed hams. Anyone can legally own a ham radio. And anyone can use the radio to receive. It's not until you hit the transmit switch, that the transgression is committed. Many prospective hams would buy a radio as they were studying for their ticket, and listen to code practices or just conversations, and trying to learn the ropes. That all goes away if a license is required to buy. And the manufacturers never likes the idea either as it would cost them sales. And that really is the bottom line. Don't ask, don't tell, as long as you pay the piper. Makes me wonder what Alinco is up to with this move.

Geez Louise, that's a pretty harsh preface. Suggesting that anyone operating a CB radio should learn radio theory is like suggesting that anyone who operates a car or truck should study to be an auto technician. I mean just think of all the "snake oil" products and automotive myths floating around out there.

There is one thing I dislike about collecting mint or NIB (New In Box) vintage CB radios from the 1970s or early 1980s. It's when my prized CB find arrives in a box that says; "Grandma's radio" or "Grandpa's radio". I want to sit in front of that "like new" 1970s CB and be a kid again, and that bubble gets burst the second I'm reminded how old I am by "Grandma's radio" or "Grandpa's radio" written on the box. It's also a little disconcerting to be reminded that the original owner probably died of old age. >: | Night Ranger Well, when we were the "kids" of the 1970's, the "adults" back then (and I use the term loosely in some cases), would be in their 70's and older now, and many have gone on to that coffee break in the sky. So yea, it's quite possible that you may end up with a haunted radio....... FYI guys, I took an online course and am 100% certified to exercise spirits from CB radios, stereos, televisions and most major household appliances. Sorry, at this time I'm still working on my toaster oven and garbage disposal certs.

... "Ol' zero-five" came dangerously close to getting a visit from the feds. He was on their radar, and it's probably a good thing he left the area when he did. His self destructive behavior sealed his fate, and probably will again. You know what they say about old dogs. I still have copies of the letters.

A while back I was searching eBay for a cheap digital clock for my shack. What I found were a ton of neat 70's and 80's digital alarm clocks, some I remembered as a kid as I would page through the Sears and JC Penny catalogs. One that caught my eye was the Proton 320, a neat design, blue display and after I read up on it I found that it got great reviews for it's audio quality. Lot's of info online too. Fast forward to yesterday. I was perusing the junk at the local Cash Converters store and what to my eyes should appear? Yup, a Proton 320! Plugged it in and it worked great aside for the dial light being out, and looked great except for a few white scuffs that came off pretty easily. So I grabbed it, paid $24.88 plus tax, brought it home, cleaned her up and this morning I replaced the dial light. It really does sound fantastic. Nice healthy bass out of a little box, just like Bose does and an awesome FM tuner, lots of stations on just a little wire and great separation. It also has a cool alarm feature where the buzzer, or radio, starts out low and ramps up over 10 seconds as not to blast you out of bed. I think the best part is that I could get my money back on eBay if I decide to let it go, and if it goes south there are plenty of good parts to hock. herculodge.typepad.com/herculodge/2009/08/good-luck-finding-a-clock-radio-that-beats-the-proton-320-you-wont.html

There are no antennas left in my old neighborhood, but if you look closely at my parents house you can still see a couple eave mounts out back and a chewed up portion of rain gutter above my old bedroom window where I ran a mobile "gutter mount" antenna.

For as long as I could remember there was a Super Scanner on North Charlotte street (Rt 663), just north of Keim street outside of Pottstown. I went by recently and sadly it's gone, an apparent victim of a new roof. That thing appeared to be completely intact too.

The crazy prices have jumped from E-Bay onto Craig's list. But I really think this guy has greatly overestimated the appeal and the rarity of those radios. President Washingtons are a dime a dozen (just like Cobra 142's). The Royce is a bit rarer, but there isn't a big demand for them either. And that Cobra 2000's box looks a little bit worn to be housing a NIB or "nearly so" radio. Interesting that he shows no real pictures of the radio itself. I'd give him $500 for all three....... IF they are truly all clean. "If" is the big question. Note that seller states.. "I HAVE NEVER USED THIS PIECE OR EVEN PLUGGED IT IN." In other words it is completely untested OR it is known not working and he's a big fat liar. Seriously, even if he had documentation and proof of original ownership is ANY 30+ year old CB radio worth $650? Really? Not in my book, but there are plenty of folks out there with more money than brains.
