legally end our old music business companies. This doesn't affect 73, other than it'll give me more time lo get on the air and have some fun and lo pursue my work with cold fusion. I enjoyed the music business, but 'Tve been there, done that.' Ten years was more than enough.

I was not surprised b the recent class action suit against ihe six major music companies i five are foreign-owned) for price fixing. But then the whole industry is corrupt, as i've discussed in my past editorials. The big winners are the six majors and big record store chains. The big losers are 98^ of the performers, U)0% of the independent record companies, and 100% of the independent record stores. Capitalism works fine until companies get big enough or work in secret groups to control distribution and prices. Lobbyist payments to Congress keeps the Feds at bay, I've testified al Congressional hearings where it was quite clear that (he committee chairman was safely in the music industry's pocket. The industry people, whom I kneu well. laughed uhout it.

The majors wltc candid. They haled the impact I was hav ing in my efforts to build the market share for independent record companies, but my CD Review vus selling about S30 million of

earned my Novice license 22 years ago, after seeing a ham radio demon* straiion as a Boy Seoul some 10 years earlier. Recently married and unable to afford new equipment, when I heard thai a local ham was selling a Heathkil SB-102,1 went for it. That SB-102 and a 40 meter dipole were my introduction to actual QSOs+

I remember looking through the Heathkit catalogs, Irving to imagine a si at ion with all the matching accessories for my SB-102. !'he XYL got me started by giving me the matching SB-630 station console for Christmas, l itis had a 24-hour digital clock, a phone patch, an SWR meter, and a 10-minute timer, all in one. I then added the matching SB-600 station speaker Not a shabby-looking station for a Novice in 1974. The SB* 102 is a 13-tube IIF SSB/CW transceiver. rated at ISO watls input—80 watts more than most of today's radios—running a pair of 6146Bs as finals.

When I upgraded to Advanced, the SB-102 got me contacts with UA. ZS. VK, and XX. I added the optional 400 Hz filter for CW, and what i difference that filter made!

Sure. I sold the SB-102 and went on to a solid-state synthesized radio with 100 memories and computer-controlled microprocessors.. but I couldn't forgel rn vision: to have a complete line of Heathkit radios and accessories.

Building the dream

Heathkit Sb 221 Manual

Several years ago I heard about a retired ham with some old gear to sell. That isit changed my shopping habits at ham tests. There was an SB-102 and an SB-200 1 kW amplifier. The SB-200 is still an extremely popular 1 kW amplifier It uses a pair of 572B tubes in parallel for finals. Together the SB-102 and the SB-200 were a popular combination in the late '60s and earlj *70s+ We worked out a great deal; he jusl wanted them to go to a good home and was not interested in the dollars.

Finding the pieces

At a local ham auction* I ran across an SB-610 monitor seopc which also matchcd the famous Heathkit 'SB green line' of equipment. Now I had live matching picces from the SB line. The station was starting to look like the Heathkit catalogs of 20 years ago, I was hooked, I had to have ¿ill the pieces to the Heathkit SB line!

Packet radio is a nice way lo find 'wanted' equipment* and I've had great succcss finding bargains for older equipment. A couple of messages out on

So what do I do with all of this outdated equipment? I have fun with it!'

Clearing a spot an a side table. 1 made a new home for my old friends, I had kept my SB-600 speaker and SB-630 console; these too joined the new family.

Heathkit Sb-303 Service Manual

As a Novice in the eariy '70s, it seemed to me that four out of five QSOs were with hams who had Heathkil equipment. Now, in the 1990s. 1 was trying to make contacts like I did 20 years ago, with so-called obsolete equipment.

Does that Heathkit combination still work? You bet it docs! No, il dt^esn't have the 100 memories, and 1 do have to wait a couple of minutes for the lubes to heat up. But what it does very well is make contacts. You're not going to hear signals coming in at less than 0. i i on a crowded band, hut how often are you really under those conditions? Remember, a clean signal from 2(1 years ago still sounds the same as a clean signal from a state-of-the-art transmitter today.

packet and soon I h;id added the SB-650 digital (niie-iubes) frequency display and the SB-620 spectrum analyser, for under S25 each. Yes, the) both worked when I plugged them in. Another packet request and I hau two SB-500 2 meter transverters added to mv collection (at nesxt-Lo-nothing prices). The SB-500 also uses 6146 finals for 50 waLts output for SSB and CW.

The next piece took some ads in the ham classifieds. 1 had only seen one SB-640 in my life, and that was ears ago al Dayton. The SB-640 is a remote YFO that interfaces with the SB line of transceivers for working split frequency.

The hardest piece to locate was the SB-110 6 meter transceiver. Most people hang on u> these '60s vintage rigs, which use 6146 lubes for finals for 180 watts PEP on SSB and 150 watts CW.

Haiiitesis will yield a bumper crop of old tube-type Hatth equipment. I've purchased complete working HP rigs for $20!

So what do I do with all of this outdated equipment? I have fun with it! When visitors comc to the shack, most arc in awe of all those dials and gleaming knobs. It's almost a shame to tell them thai, averaged out, I have Jess than $35 per piece invested in this sub-hobhy. That's less than a used state-of-the-art rig!

Am I finished wiih my collecting? No way. There is still an SB-313 shortwave receiver out there waiting for me, the last piece I'm missing for my collection! Besides, I still need more basket eases to combine with other basket cases, to come up with working units. Why do I

No, not everything works when I get it, but in most cases all [hat is required is replacing a tube or two and a quick tune-up. At hamfests there are always boxes of tubes for sale. The average price for a tube is $2, but many times they can be found for only $L

manuals for equipment I don't have yet, just in case I come across it someday. With the manuals, tune-ups are a cinch, as in mosi cases all you need is a known frequency source and a YOM. Heathkif s famous siep-by-step instructions will lead you through complete tune-ups, if need be.

Naturally, I've added Heath's last line of SB equipment to my collection. At another operating position, sits the all-solid-state SB-104A transceiver and its matching SB-604 speaker and power supply, the SB-6I4 monitor scope, and the SB-634 station console and its need more and what am I going ro do with all of these Heaihkit radios?
