Vibroplex Original (Bug)
$$$ยทยท
| Frequency | n/a |
| Power | A mechanical semi-automatic key, not a radio and not an electronic keyer. It connects like a straight key to the radio's hand-key input and makes timed dots mechanically; the operator forms the dashes by hand. |
| Modes | CW (semi-automatic 'bug' - automatic dots, manual dashes) |
| Weight | 1.5 kg (3.3 lb) |
| Year | 1905 |
| key | Binding-post terminals on the base, wired to the radio's straight-key/hand-key (KEY) jack; no electronic keyer is needed - the bug generates dot timing mechanically |
| power req | None; it is a fully mechanical key requiring no power or electronic keyer. |
A living piece of radio history that still works beautifully: the semi-automatic mechanism sends the dots for you while you shape the dashes, giving the characteristic Vibroplex rhythm many CW operators love. It is heavy and stable, simply built and endlessly adjustable, needs no power or electronic keyer, and the Deluxe's jeweled bearings add an especially smooth action. Backed by over a century of continuous production and parts support.
A bug has a real learning curve - timing the dashes by hand and tuning the weight/spacing takes practice, and poor technique sounds poor on the air. It only sends manually (no iambic squeeze, no memories), is bulky and heavy for portable use, and connects like a straight key, so operators who want machine-perfect code prefer an iambic paddle with an electronic keyer.
The Vibroplex Original is the archetypal semi-automatic 'bug,' in production since 1905: automatic dots, hand-made dashes, a heavy stable base and a distinctive swing that is part of CW culture. It is a wonderful choice for an operator who wants to learn or savor traditional bug sending; those after modern convenience and machine-timed code will prefer an iambic paddle and keyer.
The Vibroplex Original is the semi-automatic telegraph key - the 'bug' - that started it all. Introduced in 1905 and still made today in Knoxville, Tennessee, it sits between a straight key and a modern electronic paddle. Hold its lever one way and a weighted pendulum swings back and forth, automatically sending a stream of evenly spaced dots; push the lever the other way and you make the dashes by hand. You set the sending speed by sliding the weight along the pendulum arm, anywhere from around 20 words per minute to well over 50.
It is a purely mechanical instrument, so it needs no power and no electronic keyer - it wires to the radio's straight-key jack through binding posts on the base. Two versions are offered. The Original Standard has a textured black ('ECO-BLACK') powder-coated base, a non-jeweled movement and bright chrome top parts; the Original Deluxe upgrades to a chrome base, a jeweled (jewel-bearing) pivot for an especially smooth action, and red finger pieces. Either way it is a heavy, stable key - about three pounds - carrying the famous lightning-bug nameplate.
What keeps the bug beloved more than a century on is its sound: the slightly human 'swing' of hand-timed dashes against machine-steady dots is part of CW culture. The trade-off is skill - reading the weight, spacing and your own timing takes practice, and a bug rewards good technique and punishes sloppy sending. It sends only manually, with no iambic squeeze or memories. The Standard is the entry model, with the Deluxe a step up in price and finish.
For operators who prefer modern electronic keying, an iambic paddle such as the Vibroplex Iambic or the Bencher BY-1 with an electronic keyer is the alternative; the Vibroplex Vibrocube is a heavier-base paddle from the same maker.
