We already have tons of experience with, for example, the recent huge increase in the number of Extra Class licensees which fell out of the reduction in the code test speed for Extras. And the reduction in written testing for Extra. It's all one disgusting big dumbed-down bag of worms. I tune the Extra 75/40/20M phone setasides today and the recently enfranchised don't seem to be there. In volume. If anything the overall activity level in those setasides is noticeably down from what it was long before the code test speed was dropped. Don't forget sunspots. I'm talking about the much longer term thru the highs and the lows. In years gone by there was always chatter in the Extra phone setasides, not with just sunspot-affected dx, but with."locals". After the last FD I decided to dredge up a ragchew in the 20 phone setaside before I tore down. Usta be no sweat. I had to tune around for ten minutes until w3bv came on the air and we yakked for 45 minutes via ground path.. Mid day, the spots were middling and the dx was there. The only w's in the space were a small group of 8s & 9s and Alan (keeper of the k3jh pole) and I. All of us were old 1 x 2s. Message there. . . The dead spectrum problem has far more to do with getting the HF-enabled of all flavors off the Internet, off their dead butts, geting the radios, actually putting the HF antennas up and getting on the air than it does with any "bandwidth-based frequency plan" sorts of things. HEAR HEAR And *THAT'S* where the problem really is! Fiddling with licenses is only going to have a minor effect on that, if any. License changes aren't going to fix anybody's CC&Rs, or suddenly improve the sunspot number, or empower vast numbers of existing hams to figure out how to end feed a wire and actually get on the air. Perfect example of the results of dumbing-down. Bonnie also dumped her Master Plan into QRZ.com. Bad move. Those guys make us RRAPers look like wilted lilly nice guys in comparison. Check it out. I notice that she hasn't gone back at anybody with a single rebuttal. Whatta weenie SHE is. "Glory hound shoots self in foot." 73 de Jim, N2EY w3rv |

Usually this mantra pops up by some of the no code faction who has tried to promote the idea that "experimenters" in new mode technologies would somehow come out of the woodwork IF there was no code test to keep them off of 20M phone. Go figure! It's been something like twelve years since the first of the piles of nocodes hit the bands 30Mhz. Mayber it's happened and I missed it but I have yet to see or hear of a single example of a nocode experimenting with a new wide mode. For that matter none of the Extra "wideband digigeeks"who have bleated the same refrain have done anything but talk either. Worn out transparent old smokescreen, all of it. The problem with "new modes" has nothing to do with the regs, allowable bandwidths or any of the rest of the usual micro-managed "grand plans". It's a MARKETING problem, pure and simple. You go dude! I ain't buying no dayum Yugo! So...where ya been...?!?! Keeping a lower profile. I've run a bit short of patience with this funny farm. 73 Steve, K4YZ Brian w3rv |

The original research paper on that particular topic was actually published in 1945. I have a copy of it somewhere... No doubt something was done back then. A former RAF boffin named Clarke would have his geosychronous 3-satellite comm proposal published in Wireless World a couple years later. I was fortunate to read an original W.W. issue with that article. Right now ALL of the geosynchronous orbit positions are taken... :-) Mike Gingell did his PhD thesis on the polyphase network (the four- phase version, not to be confused with other "polyphase" networks) in the UK. I have a copy of that courtesy of a UK amateur. Several picked up on that thesis in the UK and Martinez' version was printed in Radio Communication magazine some time in 1973. My boss at RCA (Jim Hall, KD6JG) showed me that and it looked fascinating. I snitched some corporate computer time and analyzed it in LECAP, the RCA frequency-domain version of ECAP. I sent the results to Pat Hawker whose column ran the polyphase stuff and that was published in 1974 in Radio Communication. Jim Hall is one of the "third-method" SSB innovators and his paper done at RCA remains as a footnote mention in the "Collins SSB book" although the authors got the third-method system descriptions mixed up. Several in Yurp have used the Gingell values with success for SSB, including direct-conversion versions. One of Dan Tayloe's QRP receivers (D-C) uses that. A Japanese amateur surnamed Yoshida refined the values for even less quadrature phase error and that was published in QEX. The Gingell-Yoshida value set is most forgiving of component tolerances yet providing excellent very low error quadrature phasing across the audio voice band. Mike Gingell moved the USA and got a U.S. amateur license, was living in an eastern state and was interested in satellite reception according to his personal website. It's now 31 years later and most U.S. amateurs are ignorant of the Gingell circuit or haven't looked into it...most preferring to operate their ready-built, designed-by-commercial-engineers equipment. The (Gingell) polyphase circuit has also been the subject of papers in the IEEE Transactions on Communications in the late 1970s and 1980s for applications other than SSB. The basic PLL circuit was first described in 1932 (!) by France's H. de Bellescize but it doesn't bear a lot of resemblance to the modern PLLs using specialty ICs such as an MC145151. :-) All things are as they were then except for some profound changes.

Maybe you don't recognize Peter Martinez, G3PLX? I musta missed this one too, when did the FCC start passing out Extras to Brits?? He was experimenting with polyphase shifting networks for SSB back in 1973. (a) When did bench-futzing SSB transmitter circuitry have anything to do with putting a wideband signal on the air? (b) When did SSB become "wideband"? (c) You might note that phasing schemes for generating ssb signals have about as much applicability to ham radio today as you have ever had.
