Universal Cable Adapter
By Art Trauffer Built into a typewriter ribbon case, this adapter permits over 50 combinations of cable connections. WHEN the writer finished making this adapter he started to count the different combinations of connections that can be made with it, but when he reached 50 he gave up. Certainly, 50 is not the limit for this versatile and easily-made adapter. If you build one of these you will save much time and trouble when joining together various types of connectors in radio and electronics experimental and test work.

Tweeter Globe
By Steven Hahn This novel addition to your hi-fi system will overcome the problem of high frequency distribution. ONE problem in high fidelity reproduction is the distribution of high frequency sounds. In the low frequency range, this is a minor problem because of the comparatively large size of the speaker radiating element and the distribution patterns of the sound waves. However, as one increases the frequency, the waves begin to take on more and more the characteristics of light beams; that is, they are comparatively narrow and have a tendency to reflect from various surfaces.

All About Ham Nets
By George Hart, W1NJM Yes, there's a place for organized "rag chewing," but the byword of most ham nets is "service." ALL over the amateur radio bands you can hear them—between 500 and 1,000 groups of operators calling themselves "nets." You might hear, for example, one station say: "Old man, you're interfering with the Podunk Net. Wonder if you'd mind standing by or moving to another frequency so we can clear our traffic."

EI Picturescope
Back in 1929, a pretty girl who wanted to listen to a portable radio had to have a weightlifter for a boy friend. Nowadays, a pert lass, such as West German starlet Maria Perschy, can "lug" her own portable, in this case a Telefunken. Sports attire also seems to have dwindled over the years.
