Thank you. I did not know the history of the bug. I am used to a straight key and have problems with arthritis now. N0QFT

Hi Glen, I just did a video for you showing multiple key options for you. It should be posted before long. 73, Dave, KEØOG

$5 in 1904 is worth $175 in 2024 money. there is no doubt he was making a profit from his $5 sale.

You do not have the stop set up correctly. First the pendulum is the shaft that extends from the dash paddle to the end of the round arm. the part you call a pendulum is really the weight. The round end of the pendulum is what contacts the small loose wheel on the stop arm, not the weight. The pendulum should just barley touch the stop wheel. The stop weight will probably never move when the key is set up correctly.

True but the video is very educational about the history of Vibroplex and the bug in general.
