Re: QRP & Novice Rig Round Up - It's a Hoot!

Good info Sam. Tnx fer passing it along. I expect those old slat-board designs would still work just fine. And for those curious enuff to look into it, the vacuum tube is a lot easier to grok than the physics of transistors (altho I don't mean to make it sound like solid-state physics is impossible to understand). And there's something comforting about the glow of those tubes that's mighty attractive to me when operating in the evening. Especially for tubes with a "top cap" for the plate connection. I'm in the process of designing a xmitter right now that combines old (vacuum tube - a 2E26) with something new (a DDS driven signal source). Back in the 1950's I was stuck with one xmit frequency (I think it was 7063), because I only owned one crystal. For a teenager, xtal prices were just too high back then. So I got to understand the advantages of being able to move around with at least two or three crystals ready to hand. 73 - Bob, K6KL

The old 1950's era " slat-board " 6V6 transmitters like the one you described that I discovered in the 1955 " ARRL How To Become A Radio Amateur " are available as kits - should you be interested. Go to: http://www.nt9k.com/slatboard.html He has other kits also including the slat-board power supply. 73, Sam Neal N5AF __________________________________________________________ ------ Original Message ------ Received: Mon, 20 Feb 2017 02:34:35 PM CST From: "Bry Carling af4k@...

We all have some kind of interesting background on how we came into the radio hobby. I have already worked about 10-12 QRP stations in the NRR this week. Many QRP guys like the NRR because it is a sensible speed, and not all crazy PLUS the ops listen VERY carefully for weaker signals since most of us are using 25 - 35 watts Thanks for your comments and your interest - Bry AF4K http://NoviceRigROundup.com NOVICE RIG ROUNDUP 2017 novicerigroundup.com ANNOUNCING NOVICE RIG ROUNDUP 2017!!!

Wish I still had my Novice rig. it was a 6V6 xtal oscillator built on two strips of 1x2 wood, from an idea in an issue of CQ magazine of about 1951 or 1952 vintage, IIRC. But I built it about 1956 - when I was a bona fide Novice. The receiver was a Heathkit AR-3 I built in the Fall that year, after working in an auto-wrecking yard all summer to raise the cash. I got 90 cents an hour, and my father took half for "room and board". I'll never forget the first time I heard my own call sign coming back to me pursuant to a CQ. I was KN6ZGQ at that time. (My present call is a "used" one I asked to be assigned when the original OM passed away.) Then the first transistors became available the next year. I got one, a CK722 from Raytheon, for $2.40, with a refund of $1.40 because the price had dropped while my money was in the mail. That transistor was so fascinating that I became a builder more than an operator, and have always been that way ever since. Electronics became my lifetime profession. Even got an advanced degree in EE, and a medal while I was in the military back around 1967 for "solving" a "electronic intelligence" problem all branches of the military had been spending MILLIONS of dollars on every year -- a problem most any experienced radio ham could have handled same as I did. So I have a whole lot I owe to our "hobby" - perhaps the most useful, beneficial and valuable hobby anyone could ever engage in. May the Novice Roundup last forever ! 73 - Bob, K6KL On Monday, February 20, 2017 12:16 PM, "Bry Carling af4k@... [4sqrp]" <4sqrp@...> wrote: Thanks Bobby! jump in and join the fun, QRP friends. Begin forwarded message: From: Bobby Drummond > Date: February 20, 2017 Just a reminder that the Novice Rig Round Up is in full swing and continues until next weekend - until February 28th at 2359 UTC. Here is the URL for the NRR: www.novicerigroundup.com There is full information about this year's Novice Rig Round Up (you don't have to be running a Novice license rig to participate) and information about the previous years' NRRs. There is also a convenient online logging program (or you can choose to submit an ADIF file, for instance, when you finish, etc) When you finish you can submit something to the "Soapbox" -- including pictures -- if you'd like as well. This is my first year participating in the NRR and I'm having a ball. I'm using my homebrew MOPA rig (on 40 meters) that I've mentioned several times on the list and also using a homebrew solid state 80 meter rig. It's great to exchange NRR numbers and hear some chirps, follow some drifting VFOs and also work some rock steady novice era rigs. If you really want to take a ride on the way-back machine, work another NRR participant "duplex" for more realistic feelings of how it was back in the novice days. (Call CQ on your crystal frequency and then tune up and down that section of the band for a response that might be dozens of kilocycles away from your transmitting frequency.) There is a chat room website for setting up skeds or maybe just for the camaraderie with your fellow Novice rig brothers/sisters of key. The best part? it doesn't cost a single dime to participate (even though donations to help offset some of the expenses are appreciated) Come on, join the fun. If you've got one, get that old rig outta' the closet and enter the fray. This Novice Rig Round Up thing is a hoot! 73 de Bobby Drummond - AK4JA
