External circuitry provides 20 dB negative feedback from the external audio output stage to the audio preamp to ensure consistent performance and to reduce the effect of Supply voltage fluctuations. The age voltage derived from the emitter of the detector controls the gain of the mixer through an external decoupling network and gives approximately 60 dB of age range. The ceramic i-f filter has a...

Leaky Lines

It need not even be stated, but almost every single amateur is aghast at the prospect of the unwarranted proposal to grant a significant portion of one of our VHF bands to a group of idlers and dilletantes who have demonstrated little or no qualification for its stewardship. This group, (with some exceptions, of course, but not many), has demonstrated over and over again that it is unfit to be entrusted with so precious a resource. Their record of lawlessness and irresponsibility is a glaring...

The large scr gate capacitor of 1000 iF was the final nail that held those ringing pulses down from triggering the scr. The tone signal of course, holds on for a time determined by the finger on the tone signal oscillator, which may be miles away. Ihe total integration through the system, including that 1000 jF job, is long enough to keep the pulses down but...

Tax Revolt

The people who have been leading the way toward a revolt against the IRS and the whole tax system have worked out some interesting ways of doing things. I'm not sure how well they are getting away with it, but the claims are that no one has yet gone to prison that has done it just right. One of the basics seems to be a matter of crossing out the perjury statement on the tax return. If you stop and think about it, there should be a Miranda warning right there above that perjury statement for it...

Nixie Driver

During the construction of an electronic clock or frequency counter, the type of readout employed can be a deciding factor in the overall price of the unit. The LED (Light Emitting Diode) type of seven segment readout is quite a bit more expensive than those of the Nixie type. The driver integrated circuit fo the i ED readout generally is more expensive than the driver for the Nixie tubes. Most of the LED readouts are low voltage devices (approximately 5V) and work with a iow voltage type of...

A prescaler, in case you're a little behind current technology like the rest of us, is a helpful liule piece of test equipment that divides by ten. The fact is it is most useful for anyone messing with the VHF or UHF bands.

The Hal Morse Keyboard

Having tried out just about every code typing device to be put on the market, we couldn't pass up the chance to have 3 go at the HAL unit. To save some suspense, it is superb, it is the easiest to use of any that we've tried, and by a wide margin over some of them. The keyboard works very smoothly and positively. One other keyboard that we've used quite a bit recently was okay, but some keys had to be pushed hard, others lightly, and you had to remember which were which to prevent double...

Whether they have memories, dot insertion, or a variety of other features, they all have been second-rate in one respect, The actual keying of a grid-blocked transmitter is unsatisfactory. Most keys use a relay for transmitter keying- This allows a wide range of voltages of either polarity to be keyed. There are many drawbacks to his system, however. Unless the relay is a high-speed type...
