Bugs moving around
- Hi Bill:
I think you hit the proper point when you say "set it very light." A
properly adjusted Vibroplex should not be moving all over the table,
and if it does, it usually indicates excessive tension on the dit
retractive spring and/or the dash tension spring. Spring tension
should be just enough to provide crisp, snappy performance. On most
properly adjusted bugs, the spring tension nuts will be backed out
most or the way.
There seems to be a host of ills associated with the adjustment and
manipulation of speed keys out there, and the sound of some of them
on-air reflects this. A carefully adjusted bug should be easy to
operate and provide good readable code that is balanced and similar to
the ratio provided by the newer electronic keyers. If one follows the
instructions provided by Vibroplex or other documentation available on
the Internet, it should eliminate any such problems.
Here is a link to a pdf on bug adjustment available on the QMN/NREN
net web site, which you can share with interested individuals:
I am sure there are also a few links out there to the old QST article
that Vibroplex used to distribute explaining proper bug adjustment.
As to you-tube videos...I'm afraid to look. Does the term "blind
leading the blind" apply to videos? LOL.

The Blue Racer "feels" like it is tippy. It really has never tipped
over. Often the desktop was glossy and the bugs if they had old
rubber feet which had hardened had no ability to sit still.
If the bug moved, the operator would feel the need to hold the bug.
This the operator's didn't like because it hindered their ability to
hold the telegram in the other hand, flip the pages to the second page
of "fifty words" as telegrams were often done, tune the receiver. On
a ship the Blue Racer was quite unpopular because of its size and when
seas got rough the bugs were rendered useless because of rolling and
pitching of the ship which would alternately make the key "light" and
"heavy" and sometimes even produce a "key down" of a second or so as
stomach, bug and ship moved in a sickening shudder as the prop
- I agree on the aging rubber feet problem. The best thing to do is to
replace the feet. The second best is to "stick on" new bottoms to the
I have a sheet of 1/2 in diameter rubber jewelry box feet protectors
that are about 1/32 inch thick. They work great for putting life back
into the old hard as a rock feet that are original.
Found them in a crafts store.
The third best thing (I'll respect your top two) is to place a bug-base-
size piece of rubber shelf liner under the bug. Its foolproof, and
veeerrrry inexpensive. If you take reasonable care cutting out your
piece, it looks good too.
