Conversation with Wayne . . , so in order to further substantiate our feelings, extensive tests were conducted. Initially, this simply consisted of feeding a conventional video signal through an amplifier whose band-pass was limited to approximately 1 mc. This, however, immediately proved completely impractical, since the upper frequency requirements are determined almost entirely by the horizontal scanning frequency, presently 15,750 cps, or in other words, resulting in 2f gt 2.5 horizontal...

Paul Barton W6JAT 14666 B rry Way San Jos , California bout two years ago Jo Jennings WfiEI and his gang,1 began work on a transceiver. Numerous models were built and tested including a transistorized mode , all with a somewhat similar basic idea. This idea appears to have germinated somewhere between Jo Jennings and Don Johnson- At one time, Denny Moore put a fine printed circuit board kit on the market as an aftermath of this same project. His interests have since been sold to a...

However, the ALCO Model GDM-1 grid dip meter is a...

MAIN STREET LOS ANGELES 15, CALIF. The beast we are to consider here has a squat bulky appearance, stubby high voltage snouts, and weighs in like a razorback. Case, oil, and all it runs around one hundred pounds. Contact with this animal when it is excited is not recommended. This is the venerable pule pig transformer used by power companies. Knowledgable amateurs have been using pole transformers for years in high voltage supplies, but there has been a lack of information which dealt...
