      Small value capacitors are labeled in pF (x10^-12 F), and the power of
      ten is indicated by the third digit. So the common 104, for example, is
      read as two digit value and a power of ten exponent. E.g.,

      104 = 10 x 10^4 pF
      = 100000 x 10^-12 F
      = 10^-7 F
      = 10^-1 x 10^-6 F
      = 0.1 uF

      Tolerance and other info is indicated by additional letters.

      Happy capping! :-) 73,

        Hello to all...

        Respectfully...

        Frank, W7IS does in fact sell the extendadot system and has been for several years.

        I have been using his system on several of my faster bugs for some time now and I'm very satisfied with the materials, design and performance of his product.

        As I understand it, no one specifically asked him to build a device for the masses but he took it upon himself to do just that. The extendadot is a refreshingly simple yet well thought out design.

        I for one, have no issue re-adjusting a bug and can accomplish this feat in under a minute. Adding the extendadot arm and subsequent adjustments, was/were no problem for me.

        I also believe removing one side of the tube not only ruined the original design but likely created a "hack" look that I would certainly never display to anyone. I think I would be embarrased to show something like that publicly. If one had run it through a C&C machine and could produce your enhanced design over an over again, then maybe one might would consider it not a "hack".

        Mr. Mass, I would like to think that Frank will respect your opinion as to his designs but, don't be surprised if he doesn't send you another example to critique. Then again, with Frank, maybe he'd send you another because that's the type of gentleman he is.

        Well... that should get the "group" going again I'd say!

        Again, respectfully...

        Bob

In fact, with one small weight up near the vibrator, and one small (aluminum) weight at the far end, most of my bugs will slow to 15 wpm or speed to 40 wpm, varies by bug, but typical. I can hardly expect that isn't a good range for almost anyone.

The bug shown, not much is visible in the close-up, is a 1910 Double-Lever. But the bugs I LOVE it on are the Racers and the Juniors which have shorter levers on which to locate weights, and are thus typically, a bit fast.

There is always a scratchiness with rubbing contacts, and the new solid state radios are so fast, they try to follow it. The loading of the capacitor is all it takes to eliminate this problem. One capacitor on the bug cable takes care of all bugs, no need to mount a cap on each bug.
