      Hi, All -

      This is a sneak peek at a new toy - the fully-automatic version
      of the RotoBug, which I am calling the RotoTwin. Right now it is
      unwired, but preliminary bench tests went well. I may be able to get
      it on the air tonight. Pictures are posted in the Yahoo photo section.

      Have been enjoying all of the recent posts - I'm mostly a lurker.

        Hi, Don -

        Thanks for the comments. The fully-automatic bugs are still in development (there are 7 or so), so they are one-off for now. I am manufacturing, in a limited way, my "conventional" PaddleBugs, and am almost ready for the semi-automatic RotoBugs. I will be retiring this fall and hope to be able to "ramp up" the production.

        As in all bugs, the energy ultimately comes from the paddles. In the RotoTwin, the rotors are under low force at rest and are "dragged" into motion by the paddle arms. (This is the "Vibroplex" approach). In some previous designs, the rotor (or pendulum) was magnetically tensioned at rest, and moving the paddle arm released it into motion. (This is the "Mecograph" approach). There are advantages to both approaches from an engineering point, and trade-offs as well, but the bugs come out sounding pretty much the same. With the magnetic tension design (and some tricks of wiring), there is no need for a damper mechanism, and the instruments are very quiet in operation.

        Hope to be on 40 meters with the RT tonight or tomorrow.

          Hi, Robert -

          The two disks are actually the equivalent of the pendulum(s) in a conventional bug. They rotate back and forth a few degrees in a magnetic field to generate the dots and dashes, which are picked up by a magnetic reed switch. The brass weight on the arm attached to the rim of each disk can be moved in or out to change the speed. This system allows a wide speed range without having to adjust the duration of the dots, dashes, and spaces.

          Yeah, it does look like "wicked", but not dangerous, I hope. I won't try to get it past an airport check-in, though.

            Thanks for the quick reply Richard,
            I'm currently using a brass racer w/ my icom 706 as it has a keyer built in. Also, I'm only good to about 12 or 15 wpm so far. (slight nerve damage makes keying difficult at times)
            Looks like it would be a great key for any speed.
            Hopefully, by the time you have them available, I may be able to afford to try one.
            It's a beautiful job; excellent machine workmanship.
            Thanks for the pictures. Eye-candy for sure.

              Your Double Rotobug is brilliant!
              I am still drooling over your single Rotobug.

              Can you give us a ROM (Rough Order of Magnitude, cost$) for either the
              single or double Rotobug, plus or minus $200?

              Do you have a manual for your Double Rotobug and will you post some of
              your manuals here for the CW Bugs Group? I always enjoy reading about
              your work and luv the photos.

              Do you have a Table number for where you will be setup at Dayton?

                  Hi, Chuck -

                  Glad to have you aboard - now you know what I've been up to. I don't have a way of posting the RotoBug manual, but I will send you a copy (attached PDF). I don't really have a good handle on the price yet. As for the RotoTwin, I am not yet convinced whether the complexity of a fully-automatic instrument is warranted in terms of the outcome; the gains in convenience are not all that great, the learning curve is steeper, and you have a bit less control over the "personality" of your sending. So we shall see.

                  I won't have a table at Dayton per se, but I will be at the QRP ARCI show-and-tell night (Friday, in the Fairborn Holiday Inn) with some things to let folks take a look at. Anyone is welcome to drop by.

                  My retirement is at the end of the summer, and I hope to have more time for things radio and telegraphic.
