Hi, at the moment I'm refurbishing an old radio that was originally built from a project in the 1960 ARRL Handbook Page 119 The 2*4+1 Superhet, it is a superb design and works really well for such a simple receiver, is it possible to find out who designed it? I can't find any reference to that in the project, I'm writing up the refurbishment and would like any info on the original design.. That rx is one of a long series of 80/40 "band imaging" sets to come out of ARRL Hq. They were all designed and built by staffers. Some ARRL Handbook projects were QST articles first, while others were "built for the Handbook" and never appeared in QST or any other League publication. Most were built by HQ staffers, but a few were "from outside". IIRC the 2X4+1 was built "for the Handbook" and its designer/builder(s) is/are unknown. W1DX was the Handbook editor in those times but he's SK now, as are almost all Hq staff of that generation except for W1NJM. It "looks like" a W1DX project to me, though that's just a guess. He was very interested in getting the most performance out of relatively simple receivers. His 1957 QST article "What's Wrong With Our Present Receivers" is a must-read even today. 73 de Jim, N2EY I think you're right about it being from W1DX, and that it's one of many using the same basic scheme. I have the 1961 Handbook, and it has the same receiver. Plus, right before it a simpler receiver that shows a strong similariy to the 2X4+1, the "SimpleX Super". But I can almost picture the latter in a QST. It has a distinctive home made dial, and I think I've seen it elsewhere. And then I started poking around, and it doesn't look like they specify the dates of the QSTs where the articles originally appeared. This seems to be a policy that varied over time. I know a few years later, they would tend to specify the date of the original article, but I'm not even sure if it was completely common. So I wouldn't completely rule out that the article did run in an earlier QST. It surely would not have been more than a few years earlier, since as you say this sort of receiver tended to appear regularly, and after a few years they'd have a more recent construction article to put in the Handbook. If someone had the annual indexes from around that time handy, it would be real easy to check whether this was a Handbook-only article or not. Michael VE2BVW Why don't you email the ARRL and ask them? Henry |
