"N2EY" wrote But NCVEC's proposal wants to do just that. Read the "21st Century" paper - it's a blueprint for the NCVEC proposal. I'm having some doubts about the "21st Century" paper authorship. I can certainly understand that. KL7-whatever-his-call-is KL7CC claims W3BE as a co-author, yet W3BE in his comments to FCC comes down in opposition to most of those ideas like free upgrades as looney-tune-stupid (which they are). All it takes to claim somebody as coauthor is for them to contribute a few things. They don't have to agree with the entire paper. But I do think that someone who is as much at odds with that paper as the comments reveal would have demanded their name be removed from the author list. What really tells the tale is who signed the NCVEC submittal to FCC. It wasn't either of the hams you mentioned above. For the record, I find the following NCVEC proposal ideas to be "looney-tune-stupid" (great phrase): - Limitations on homebrewing - Free upgrade to General for post-March-21-1987 Techs and Tech Pluses - Free upgrade to Extra for Advanceds - 30 volt rule - Special callsign block reserved only for newbies - Any replacement of relevant regs questions by "signed statement" nonsense. (If it takes a few more questions to test regs knowledge, add 'em) Your proposal looks better and better, Hans. 73 de Jim, N2EY |

OK, here goes: Way back in the 1930s, hams began to replace their "blooper" (regenerative) receivers with "super-hets" (superheterodynes). The added complexity of the "super" was justified by the invention of the single signal crystal filter, which gave improved adjacent-channel selectivity. Those early ham supers almost all used an IF around 455 kHz, because the available crystal filter systems worked best around that frequency. The better ones had one or preferably two RF stages before the mixer, to reduce image response and override the mixer noise. A top receiver of those days might have two RF stages and three IF stages, plus a couple of audio stages and the mixer and detector. And even so, image response was a problem. After WW2, the trend moved towards "double conversion". The first IF was typically in the low HF region, to reduce images, and the second IF much lower, to get selectivity. Some designs like Collins kept the 455 kHz second IF, while many others (National, Hallicrafters) used a first IF around 1700 or 2215 kHz and a second IF of 50-60 kHz. Such a low second IF meant that LC circuits could be used for the selectivity. Such receivers were arguably "better" - and unarguably more complex. Compare the prewar National NC-101X with the mid-50s NC-300, or a typical homebrew super of the '30s with an HBR. And while better in some ways, they were worse in others. Then packaged high-frequency crystal filters were developed (about 1957), followed by improved mixer designs such as the Pullen mixer. It became possible to design receivers with a high IF for image rejection, no RF stages and a much reduced parts count. The Squires Sanders SS-1R is an example of such a design. It is simpler than, say, an NC-300, as well as smaller, lighter and less power-hungry. There are lots of other examples. Compare an Elecraft K2 with almost any other current amateur HF transceiver - then compare the specs and features. In many ways its high performance is a direct result of the relative simplicity. Simplification can be an improvement. But simplicity isn't always simple, or easy. 73 de Jim, N2EY |

Antenna tuners (more properly called feed line tuners) are a crutch for people who can't manage to build a proper antenna to fool their transmitter into thinking it has a proper antenna. If you use low loss feedline and a tuner, it doesn't much matter how bad the antenna's SWR is. Low loss feedline means that you don't lose much RF energy as it bounced back off the bad antenna to the tuner, and then back to the antenna. Actually, lossy feedline can make your SWR look better. The propagation delays of these bounces are of little importance for the narrowband modes we use on HF (SSB, CW, RTTY and such). I use some old Ethernet cable (essentially foam RG8U) to run the feed from the shack upstairs down to the basement, and there I switch over to coax more weather resistant thru a small hole in the wall (caulked to keep bugs out) to the vertical in the back yard. It's a pre WARC multiband HF vertical. A major reason for bad antennas is a lack of space or place to install a good antenna. |

When I was in college we buit a 10w CW transmitter and tested the results into a dummy load. No knowledge of code was needed or expected. hehe, now that sounds like fun! 8^0 - Mike KB3EIA - |

Of the current "crop" of Cadets at th local unit, seven out of 12 are licensed Amateurs, six of them have already one on to General. What ages are we talking about? CAP cadets can be 12 to 21 if they join before age 18, however the one's I am addressing specifically are all between 15 to 17. (Ironically the 17 year old is the one who has yet to upgrade!) And who's making the call on what's irrelevant and what's unnecessary...?!?! FCC makes that call. And note this: One of the arguments for dumping Element 1 is the claim that when it was dumped for Tech, the whole ARS didn't fall apart. So if we get over 323,000 free upgrades to General with no testing and the ARS doesn't fall apart..... Isn't that the "call" of the person seeking Amateur licensure...?!?! Nope. A person might think that 20 wpm code tests given by FCC examiners are relevant and necessary to an Extra license, but they will have a hard time finding them today.. Point taken, Jim, but what I was trying (unsuccessfully) to say was that it's partly the applicant's decision to decide if acquiring the knowledge or skill was appropriate to gaining the license...In other words, are the benefits of licensure worth the time and effort expended to get it...?!?! Any better? 73 Steve, K4YZ |

Do you recall TAFKARJ commenting on those great AMATEUR CW Operators saving the day during WWII? When AMATEUR Radio was off the air? Welp, there's another one who cannot admit that he was wrong. Ever. Two peas in a pod. |

You've only had one woman in your entire life, Brain? You met and dated one and only one woman your ENTIRE life? Yes, there a lot of "former" girlfriends. A bit jealous, are you? Perhaps it's that residual fecal material behind your ears from plugging and unplugging your head in the wrong orifice all the time... You might try toothpaste, too.... Steve, K4YZ Steve, I happen to be married. Out of respect for my wife I don't dredge up the velcroed past. But you do. bb |
