Frequency, so as to achieve fast rise time of the square wave. ) However, for this application we are not constrained to use germanium power transistors, since we wish to convert only a watt or two. For switching currents of this order there are many inexpensive germanium computertransistors that have cutoff-frequencies of several megacycles. Now, it is the core-material that is the determining factor in limiting our frequency and so we can almost immediately forget C-cores and tape-wound...

In the May column I said we would discuss antenna stacking and matching- tins month. Refer to that column for a coaxial feedline loss chart, Placing two identical antennas side by side, or one above the other, will increase the gain over a single beam by 3 db, the same as doubling your transmitted power, his increase also applies to receiving. In other words, if a single beam has 10 db gain, stacking two of them would yield 13 db and four beams in a quad would bring the gain to 16 db. The...

Honk Olson W6GXN 3780 Starr King Circle Palo Alto, Calif. Often it becomes desirable to include a single tube in an otherwise transistorized system for high-input-impedance, dynamic-range, or age reasons. A case in point is in the rf front-end of a Yt F mobile receiver, otherwise all transistors. It was found to be the least trouble in this receiver to use a single 6DS4 nuvistor as the first rf amplifier.

As most surplus-minded amateurs know, the ART-13 (and its Naval counterpart, the ATC) is a Collins autotune transmitter designed or operation mainly between 2 and 18.1 mc. In service, they drew their power from a 28 volt dvnamotor which produced DC voltages of 450, 750, and 1150, The medium voltage was used on the 813 and 81s at high altitude while the highest one was used at altitudes less than 25,000 feet.
