Need to remember that in the days when bugs were king, the typical
voltage being keyed was between a cathode(s) and ground (often a
couple hundred volts at several hundred ma) or bias voltage (75, 105,
150 volts). Turn off the lights and key the bug keying an 807 rig, and
you could see the sparks.
The problem I dealt with is not contact bounce, but contacts that do not
make a low enough resistance connection to trigger the logic properly. It
sounded like that was Werner's problem too.
It's easy to see the contact resistance issue using a scope on the key line.
The key voltage simply isn't b

I suspect you're experiencing "scratchy" or intermittent dits, not chirp.
("Chirp" is when your frequency shifts up or down during the initial
milliseconds after the key closes)
As others pointed out, a good low resistance contact is *required* by modern
rigs that key a low voltage/low current li
I guess the K3 just likes your bug!
First, make sure the contacts are mating squarely. Then measure the
continuity when the dot contacts are resting closed. It should be a
dead short. If there is any resistance find out where and correct it.
Assuming that is okay, how many dits does the bug gener

Hello group
Was wondering if anyone had the same experience as I have.
Got a Vibroplex Classic a few months ago and took quite awhile
These are kind of neat:

Guys,
Gert, PA3GUF makes handmade bugs.
Wanna see the Blue GUF Racer? A GUF speed X bug? A camelback key? Or an
admirality key? All handmade. Watch the slideshow on his site.
I have tried out many of his bugs and I love them.

Enjoy

One thing about Vibroplex: they never figured out how to make a weight!!
Their weights are small in diameter. That means they essentially make the
pendulum thicker! That doesn't work worth a darn.
My Vibroplex will drop to about 23 WPM with THREE Vibroplex weights loading
up the pendulum.

I had the same problem 30 yrs ago. Ended up working the keyer with my

I think if I were to buy a new bug today (I've thought about it), I'd
get a VIZ bug rather than a Vibroplex. I believe the VIZ to be a bit
better built and I hear they are more easily used at the slower speeds
(15-20 wpm).
What contest doesn't allow keyers? Maybe the SKCC sprints?
