I've been lurking on this debate, but your post clinches it for me. Some one else mentioned the other day (sorry, but I deleted it and don't have the senders name) that ARRL is, after all, promoting a mode of operation that many within that very organization would just as soon see go bye bye in 1999 with the commercial operators. So... my suggestions: 1. For those who still want the QRG for the cheap rocks, agree on a pad value to bump up or down a couple KC. Even mediocre selectivity should handle that, and all but the most recalcitrant oscillators will allow a little pulling of a rock. 2. West Coasters (like me) rarely get blasted with 80m 1AW sigs. Just not that strong out here, and not much problem. 3. Be glad that SOMEONE other than us (a decided minority) still thinks CW is a GOOD thing! Why stir the hornets? 4. Like Clayton says, wait it out! It's only a few hours each day. BTW, my homebrew 6V6 glowbugge has but one rock - 3.523 doubled to 7.046, which is just under the 1AW QST QRG of 7.048 (I believe). They boom in here 20 over, even this far out with a spotless sun. I just padded my rock a tad and use a narrow filter on the signal gatherin' box and have at it. Heck - one of these days, I may just get my 25 WPM certificate while waiting for the band to open! Take care all.

IF 1AW has a legit reason such as wanting to be within 2.5khz of the 3579R545 tv rock frequency because of its use as a heterodyne frequency, then that is fine. If it wants to be there because of tradition, that is fine, too. Unfortunately, 3579R545 is a nice cheap rock frequency that lots of folks can use. Since that rock is so ubiquitous, it would not hurt 1AW to up 2-3 khz, if the above first reason was not important. It would not hurt them to down 5 either, except for the traffic nets there. But, as I said earlier, it doesn't bother my regens..... mebbee folks should run proper regen receivers, where possible. It does bother the usual lesser boatanchor or glowbug receiver that a surprising number of folks still use. It also bothers the usual kenicoyasawhooie without tight filters. Also, the 3 hours they use are the most popular 3 hours in the evening. Actually, if I had my druthers, I would like to see 1AW park squarely on 3600.000 khz as a frequency marker station in addition to the bulletins. Now THAT would be a good service, too. Also, I would like to see a 24h bulletin/code run rather than the several hours here and there. But, it might also mean that folks might want to look into various ways of making the lesser gear run a little more better, too --- (it is amazing what a very simple filter will do on 1AW, even at audio). Lessee.... taketh a fine one henery choke, and several 0.1 mikeymike condensers, therewith, as a peaked audio filter.... Works better than most folks let out. 73/ZUT DE NA4G/Bob UP

Yup, I'd consider asking. I'd think that 99.99% of the people listening to the 1AW broadcasts have VFO receive control, while many hundreds of QRPers and Glowbugger don't. The ARRL works for us! Why shouldn't we ask? Regards, /John

Woops. 3600kc has been the KYN freq. for 200 years now. How about W1AW code practice on say.....3890kc. Now there's a good idea. Right up there where those no-code types can easily find it. I'm sure it would be a great encouragment to the sidewinders. Perhaps a bit of a power increase would be appropriate too. N4LQ

Date: Fri, 9 May 1997 13:10:41 -0800 From: "Kenneth G. Gordon" <keng@uidaho.edu> Subject: Very old receiver... I have had the following described receiver for a number of years. I rescued it from being thrown out by our Physics Department here at the U. of I. I have NO idea why they would even have such a thing. It is mounted on what looks like a mahogany board, 17" long by 7.5" wide by 3/4" thick. The far left end of the board has three metal plates screwed to it, black paint on silver, which say, "GROUND", "AERIAL", and "DETECTOR", reading from back to front. Above each plate there are silver colored (probably nickle or german-silver) thumb screws, one each for the aerial and ground and two for the detector. Just to the right of the thumb-screw connectors, there is mounted a mahogany box with a sloping front and an overhanging lid. The box is about 6" high (including lid) 7.5" wide and 7" deep at the bottom sloping to 5.5" deep at the top. The front of the box is made of black bakelite and has 4 rotary tap switches with exposed circular contacts on them. The top two switches have 24 contacts. The bottom left one has 7 contacts and two end stops. The right bottom one has 3 contacts and two end stops. All four knobs are original black round ones. The right side of the box has a hole centered in it about 4" in diameter, and sticking out of the hole is a large coil, made of what looks like #20 gauge, green-cotton covered wire. The turns of the coil are covered with a layer of cardboard. On the end of the coil is a piece of circular bakelite with another tap switch (with knob) sticking out of it. This switch has 8 contacts and two end stops. The coil/switch combo slides in and out of the box on two 1/4" diameter rails, 2" apart. The rails are fixed into another piece of mahogany which is mounted near the right end of the mounting board. On the end of the rail mount, there is a decal which says, "Electro Importing Company, New York" On the very front of the mounting board, centered between the two bottom tap switches there are two more incomplete thumb-screw connectors. Below them there is another metal plate which reads, "PHONES" The moveable coil is slightly damaged in that the screws which held the bakelite plate on its end have fallen out and some of the wires which run to the tap switch are disconnected. However, it doesn't look to me as if it would be hard to fix. Does anyone know what this thing is, who might want it, and what it would be worth? Thanks, Ken W7EKB

Date: Fri, 9 May 1997 15:20:03 -0800 From: "Kenneth G. Gordon" <keng@uidaho.edu> Subject: Possible interesting project... I have been in contact with Bob Collings of the Collings Foundation, headquartered in Stow, Massachusetts. Their address is: Box 248, and their telephone number is (508)-568-8924. FAX is (508)-568-8231. This foundation has restored a B-17 and a B-24 among other warplanes, and annually flies them to many places in the U.S. The organization appears to be a mostly volunteer organization, although there may be others on these lists who can fill in details. In any case, when I visited the planes about 2 years ago, I was extremely disappointed to see that their radio operators' positions were not only not restored at all, but were almost completely bare. In one, there were a few TU-xx tuning units. No transmitters, no BC-348s, no ARC-5s, no BC-191/375, no dynamotors, no anything. I am wondering if there are others on these lists who feel as I do, that such pieces of American history as the B-17 and B-24 should be complete in as great a detail as possible. I understand that this B-24 is the only one in the world still flying out of the over 18,000 built. Bob Collings FAXed me 9 pages out of the B-17 manuals which show the radio equipment which was originally installed. I would be pleased to FAX these pages to anyone interested (after 7:00PM PST please). He indicated to me that his foundation would be extremely interested in getting both period equipment and the operators to man it. Trips and/or rides in the planes were mentioned. I mentioned the BoatAnchors to him as a group of highly skilled radio people who might be interested in helping with such a project. So what do you all think? Kenneth G. Gordon W7EKB 226 N.

I've seen ads from Electro Importing Company in 1920s radio magazines. They sold radio receiver parts to home-brewers. You most likely have a nicely constructed, home-brew receiver from the early-to mid-1920s. You didn't mention any battery terminals, so it would have had a cat's whisker and galena crystal detector. However, it might be possible to upgrade with one of those new-fangled De Forest diode toobs :-) <<< more snips >>> >Does anyone know what this thing is, who might want it, and what it >would be worth? You could try advertising your receiver in the newsgroup rec.antiques.radio+phono. There are collectors out there who love these sets. It would be helpful if you could offer detailed photos to prospective buyers, either online or by snail mail. Can't really help you with value, but you might get a good sense of value by soliciting offers in the newsgroup. Another possibility is to put the set up for auction on the eBay Auction Web. This is a very popular automated online auction service at www.ebay.com/aw/ Good luck! - --73 Carl

Someone before me put a solid state DC-to-DC converter that delivers around 24 volts. Current drain is less than a mil. Otherwise you can get three 9 v batteries use 2-1/2 of them in series. You'll have to open up one and tap it. Once done they can be taped up and soldered in and they should last for 'shelf life'. 73, E. V.
