I drove an 18 for a living and retired in 84 and haven't keyed anything since. RM~ Back in '66 I put one of those (pre-bucket brigade) delay boxes* with a spring and two transducers in line with my audio and some of the locals thought the echo was due to the enormous power level, similar to 15 meter multipath, rather than just a precursor to today's echo-mike. *note - those delay boxes were more commonly used in conjunction with automotive 8-track players, and would make that distinctive boing effect whenever you hit a pothole or crossed the tracks too fast. ;-) Well, since the topic is shifting, can anyone tell me what the echo is supposed to do? in my travels, with my CB on, I can "hear" people with echo mic's and I'll be darned if I can hear them well at all. Now echo AND way overmodulated, now there's the ticket to complete unintelligibility! (is that a word?) - Mike - They "think" it makes them sound better or more cool, not sure which. Problem is, most are turned up TOO far. Some isn't so objectionable and doesn't sound bad, even though they're not supposed to be permitted per part 95. I've heard so many that sounded like they were talking either underwater or with a mouth full of something. REALLY SUCKED. Being both a ham and Cber, I can't see what their sense of existence is. Then too, you got everyone and his brother cranking up the RF out, and if they go channel hopping, that bleeds like hell. I had to take a double take one time when I and a friend of mine were in another CB shop, and actually heard two CBers swear off the extra garbage and go back to stock TO HEAR! WOW. I asked my friend if I heard right, and he agreed. I don't do any mods to CBs or other radios unless permitted by law or needed to get the thing working, when a unit comes to my shop. Many don't like my approach, but so be it. Lou |

Audio enhancement
All modern ham rigs incorporate compression in the audio chain; this effective pushes up the room sound a bit without the echo/reverb being overpowering. It is puzzling why hams have not commonly adapted well-known psychoacoustic observables to increase intelligibility. These include: a 50 ms delay on transmit; and binaural (delay and phase invert) synthesis on received. The latter has had some exposure in recent years. I recall using both the of these circa 1985 at Field Day with pro audio outboard boxes. The problem--on transmit--is isolating them from the RF so they don't overload. CB has always had an over the top approach to audio--which rather defeats the purpose of said synthesis. Anyway, old stuff, well-known to music producers and some audio engineers. 73, Chip N1IR |

RC,
Instead of playing the 'game' of posting a reply to anything I post. Why don't you be helpful to the original poster and attempt to answer his question.

Hi OM, More efficient that what, a resistor? 75% less energy than what, a resistor? The eh antenna is one of several of a class that take more effort for less return than simply putting up as much wire as you have room for - even if it is the same size as any of these "amazing!" antennas. The absurd claims that attend the cfa/eh/fractal crowing societies is matched by their inability to prove them except through their own special math (never mind the S-Meter). However, there are those who argue SWLers need poor antennas and I suppose these fit the bill nicely. The technical equivalent of cell phones VS string-and-dixie cups tho'. 73's Richard Clark, KB7QHC .. |

RC,
The prior post to mine in this thread was a reference to the EH Antenna. Yes I have an 'ego' and apparently your have an "EGO" too. Hey, I try to be helpful and keep things positive. I did not play Twenty Questions : I posted three. I then provided Eight Links to more EH Antenna Information. [ Not Six Links. ] I also posted Eight Links related to the prior poster's Screen Name: "JohnJacobJingleHimerSchmidt" {JJJHS} [ It's called relating to people / a side-bar. ] You have the tendency to state you opinions as facts; and thereby discount all other opinions. For some the EH Antenna may be a matter of 'faith' and to the extent that it "Works" in some form or fashion: Hey It WORKS ! Your technical details valid or not, have very little relevance to them and 'their' EH Antenna. So Say I - My Opinions Stated as Facts ~ RHF .. .. = = = Richard Clark wrote in message = = = . ..

Why don't you be helpful to the original poster and attempt to answer his question. Like you? ;-) Instead of playing twenty questions: First - What type (name) antenna is he talking about ? Second - What is your 'expert' opinion about this antenna ? Third - What are the technical aspects of this antenna ? Let's all note that it was your introduction of 6 off-topic links to an antenna who I have already responded to against these same three preceding questions. Hi OM, The eh and their ilk are on every sucker list on the web. It is a simple matter to NOT cross post your responses if they don't shine under examination. It is also a simply matter to either stay on-topic, or to at least follow your own side-thread. Respond to the technical issue, or learn to unlink your posts. 73's Richard Clark, KB7QHC |

Hi Bill, AM. You've never tried it when your car antenna works every time? I bet you have rabbit ears embedded in your windshield. O Ye of little Faith! Yahoo's very limited experience will probably miss this simple observation of an antenna that WORKS. He would also probably miss the common sense suggestion that AM DXers use automobile radios for their listening - on long antennas. I keep praying for the "whole house wiring" antenna to work with my TV. Won't work because the BPL is resonating with the fractal topology? 73's Richard Clark, KB7QHC |

I would suggest that they check-out the "EH Antennas" eGroup on YAHOO; with it's 600+ Members and more than 4600 Messages posted about the EH Antenna by actual users of the EH Antenna. "EH Antennas" eGroup on YAHOO ! http://groups.yahoo.com/group/eh-antenna/ .. .. However, going to the trouble with the eh when you could as easily use rabbit ears purchased at Radio Shack must bring with it what Yahoo cites as the misty-eyed boon of faith (which accounts for easily 20 over S9 signals in an S1 field of noise where the faithless only hear static).
