How to search

sten gun
pages with both words
"sten gun"
the words together, as a phrase
sten OR sterling
either one (| works too)
sten -replica
leave out pages that mention “replica”

Without quotes, the last word also matches longer words that start with it (sten finds Stenophylla), and close word forms count (rifle finds rifles). Tick Exact words to match whole words only.

Other words for the same thing are searched too (uniselector also finds stepping switch), ranked below pages with your own words; the results say what else was searched. Quotes or Exact words turn that off.

Whole deep dives are listed first, then the pages inside them. Click a topic under the box to narrow the results.

Tick Photos to search the captions of every photo and diagram; each picture opens where it sits in its volume. The Show row narrows to one kind of result: volumes, deep dives, photos, parts lists, Library documents or downloads.

    Volumes

    1. Vol 1 RTTY on the Air — Vol 1: Two Tones on the Air Take the teletype's five-bit code off the wire and put it on a radio wave, and you have RTTY. It comes down to two audio tones 170 Hz apart — and one detail about sidebands that has confused hams for seventy years.
    2. Vol 2 RTTY on the Air — Vol 2: The Terminal Unit and the Crossed Bananas Between the receiver and the teleprinter sat a box of filters that turned two wobbling tones back into text — and a little green oscilloscope you tuned by watching two glowing ellipses cross. This is the craft of running RTTY.
