WA2HOM Operating Notes – April 10, 2010

Yesterday, it was just me down at the museum. I made a couple of great contacts, though.

The first was with Fred, KI4XH. Fred was operating his Collins S-Line gear, and keying it with a bug. About halfway through the QSO, he switched over to a VibroKeyer single-lever paddle, keying a Hallicrafters HA-1 keyer.

The HA-1, or T.O. Keyer, was a commercialization of the vaccum-tube keyer designed by W9TO. in the 1950s. It occurred to me that maybe building one of these things is something that I could do with al the tubes that I have. Unfortunately, I can’t seem to find the schematic on the Net. There is an an article in the May 1959 issue of QST by W9TO, but this is for the first transistor keyer. If any of you have a schematic and can scan it for me, or can point me to where I can find it, I would appreciate it.

After making a couple of CW contacts, I thought I’d try making a phone contact. Tuning to 7220 kHz, I found our favorite frequency occupied by W0S, a special event station commemorating the sinking of the Titanic. W0S was operating from the Titanic Museum in Branson, MO. According to their website, “This event will commemorate the heroic efforts of Harold McBride and John ‘Jack’ Phillips as they sat at the Marconi radio in the Titanic sending the first ever SOS.” They’ll be on the air until 2200 UTC Sunday, April 11.

My last QSO was with W1T, a station that was also commemorating the sinking of the Titanic. I made the contact on 14.050 MHz. W1T was operating from somewhere in Maine. At first, I thought that perhaps this was a CW operation from W0S, but it was a completely separate operation. I was unable to find any information on the Net about this station, but they did give me QSL info, so I can get a card from them.

In searching the Net, I found a third special event station commemorating the Titanic. This is an operation of the Titanic Historical Society, which is located in the Springfield, MA area. If I’d known about this, I bet that I could have worked them. Maybe next year.

    Found the Operating and Service Manual in PDF File format at this site:


    A 15-page document with schematic on page 15.

    I liked it soo much when it came out but couldn’t afford to buy it. So, from Hallicrafters I purchased the cabinet, grill, main function switch, and the most important item the relay and built it myself.

    Still have it today but haven’t used it in many years. Wouldn’t sell it for anything. It worked really great for an early keyer.

    Very cool! TNX!
