Real Radios Glow in the Dark !

This is an interior shot of my Central Electronics 600-L Broadband Amplifier, manufactured circa 1956. It runs a single 813 at 600 watts input. The blue glowing tubes are type 866-AX -- same base as the more familiar 866-A but a smaller envelope. The other tubes are a VR-75 and an 812 which is used as a screen supply regulator.

The Shack

Construction completed May 2011

 

In 2009, the XYL and I retired and moved from Phoenix to the Las Vegas area where our two daughters and their families had lived for several years. Of course I brought my collection of vintage gear along, and after operating with a few of the old rigs in a spare bedroom for a year or so, it was "agreed" that a shack and workshop should be set up separate from the house, perhaps in a back yard building. This is what eventually resulted. It's basically a glorified 10 x 20 tool shed, insulated and air conditioned, and has a heathy supply of 240VAC to a subpanel with several branch circuits.

The Hexagonal Beam

Installed Dec. 29, 2012

This hexagonal beam is a G3TXQ/K4KIO broadband type, supplied as a pre-cut kit by Roger, NA4RR (http://www.na4rr.com). Strapped to the mast below the base plate is a Radio Works T-4 Line Isolator (http://www.radioworks.com). The rotator is a CDE Ham-III.

 

Behind the shack at left is a sectional mil-surplus fiberglass supporting pole for the center insulator of my CCD antenna (http://www.ccdantennas.com ). (The device in the center is a lamp post for illuminating the bike path which is on the other side of the block wall).

 

        

Supporting the beam is a mil-surplus crank-up telescoping pole made for the U.S. Corps of Engineers, purchased from John Baransky, a surplus dealer in Wyoming, PA, eBay I.D. jbaran33.

Equipment Interconnection

The Switcher, remote switching boxes, and cabling system which I originally designed and installed in my Phoenix shack have now been modified and implemented in the new Nevada shack. All my gear can now be selected by the Switcher for connection into the system and can be operated in virtually any combination. The Switcher schematics ran to 22 pages; in addition, there are 16 pages of remote switching box schematics, cable layout plans, and 'from-to' wire lists. The project, although time consuming, was actually fun for me, and it's good to have everything set up and working again.

*********************************

So why all the old gear, anyway??

In the opinions of the unenlightened, the majority of these vintage rigs are most ideally suited for use as marine mooring devices. However, it turns out that there is a sizeable number of 'veteran' hams once again indulging and enjoying our common appreciation of ham gear manufactured by American companies in the 50's and 60's. We often affectionately refer to these rigs as 'boatanchors' (or 'BA's) owing to their considerable weight and size. Many of us derive great pleasure and satisfaction from the BA restoration process and subsequent operation of the gear; others are most gratified with the display quality of their collections, preferring not to actually put them back on the air; still others, driven by their entrepreneurial spirit, enjoy continuously buying, trading, and selling BA's. No matter what our proclivities, most of us can be found haunting eBay, qth.com, eham.net, the plethora of specialized e-mail lists/groups/reflectors, and hamfests in search of buyers, sellers, parts, advice, and commiseration.

Yes, a large part of the BA allure is nostalgia -- our long-lasting memories of the now-classic rigs that we drooled over at the radio store or at the well-heeled ham's shack back when we were high school/college kids. But now that we find ourselves in a position to own some of those rigs, many of us have rekindled our interest in these fine specimens of American ingenuity and in the task of bringing them back to life. It follows almost universally that our BA collections tend to snowball, being limited only by ambition, technical expertise, space, and money, and indeed folks with ample amounts of each have built some really impressive, multi-room collections (see NE7X or W9EVT, for example).  By comparison, my little shack and collection of gear is rather modest, but I continue to derive great pleasure from this facet of Amateur Radio and expect to do so for the duration.
