Then for 30 seconds, as the phasing changes through , the end towers are fed interlocking dots and dashes. Erwin Schrodinger died in his native Vienna, Jan. The unit also provides a delayed switch -off action to avoid cutoff due to momentary signal fading. Unavailability of replacement parts is the greatest cause of both public and service industry complaint against manufacturers and distributors.

While the Benco T -1 translator is completely weatherproofed and may be mounted outdoors on the antenna support, it is highly desirable, if jtevh, to have a small building available for tools, spares and human comfort.

Mtech output should come before the tone controls because of the lack of linearity in these circuits. If the best transmitting site happens to be some distance away from the best receiving site, a coaxial cable system will have to be used to bring the received signal to the translator. Servicing, Communications, Preparation F.

Vertical or horizontal mounting. Narrow range phasing control for accurate alignment. Notify the FCC a little ahead of your intention to conduct ontests so you can conduct them n as installation is complete. Atlas Publishing and Distributing Co.


A simple yet complete unit, it lends itself easily to analysis and circuitry comparisons. What technician hasn’t watched the beautiful if response curve he had developed on the scope screen change to a horribly twisted affair just because he moved the alignment generator lead or turned the chassis over?

Limit advertising claims to demonstrable performance in the field. Earlier masers, as developed by Hughes and Bell Laboratories, require so much power that they can be operated only utech short pulses. You do not need a high school diploma or previous experience.

The translator transmitting antenna should not have ic30 horizontal directivity. Wright, Cedar Street, Springfield, Mass. The circuit oscillates at about 1, cycles.

The polar diagram of the selected antenna should, as far as possible, cover only the populated area of the village and have a minimum of back radiation and spurious side lobes.

Naturally, sunlight or a bright lamp is essential. To calibrate, set the range switch to the 5 -volt position and touch the test MARCH, leads to a 5 -volt source, preferably at 1, cycles, and adjust R10 for a full – scale reading.

Complete stereo cen ters plus two excellent power amplifiers. We do not know how much is reflected. His career started while a schoolboy, when, as he said, he was the chief and only laboratory assistant to Dr. More recently RCA and Remington Rand reported on an experiment in exchanging computer programs using plain English between data processing systems of different manufacturers.


This is done by using a high -speed coaxial switcher which can switch these vhf currents from point to point without introducing significant mismatches in the lines involved.

Htech from collector to collector and base to base are square, with little or no overshoot. Unique cross- reference system lets you find any fact fast: Response is essentially flat from 20 cycles to about kc.

Large upper circle is receiver detector, smaller lower one, the infrared source. It uses a rapidly rotating mirror which scans the sky for other planes. This lets capacitor C5 charge through the 47, and 18, -ohm resistors in the probe assembly. All you have to do is drop in to see your jyech Tung -Sol distributor and ask him to put you on the Tung -Sol Tips mailing list.
