Cation distance, operating frequencies, orbit number and phase. At this writing, SATCOMM-64 can print out detailed reports covering OSCARS 9, 10, 11 and 12, RS-5, 7, 10 and 11, MIR, Kivant, Salyut-7 and weather research satellites (GOES WEFAX, NOAA, Meteor). Whenever desired, you can replace any of these with new satellite choices. Additional program features include choice of screen and printed report or screen alone easily altered defaults (start time, time increment and so on) and automatic...

Designing Lc Filters Using Svc Filter Tables

Tables used for designing filters with standard-value capacitors (SVCs) are now twice as flexible as before These tables make passive LC audio filter design easier, because they can now be used to determine standard-value inductor needs also this article shows you how. NOTES ON A LIGHTWEIGHT, PORTABLE CW TRANSMITTER WITH A TRANSFORMERLESS POWER SUPPLY- 11 For RF outputs of more than a few watts, the portability of an ac-operated rig is usually hampered by the presence of a bulky power...

Yaesus mini HTk The smallest smartest toughest radios Anywhere

Whether you're a Novice or Extra class operator, you're sure to appreci ate the high power, durability and size of Yaesu's FT-23R Series mini-HTs. lb begin with, you'll find a model that's right on your wavelength.The 2-meter FT-23R.The 220-MHz FT-33R. Or the 440 MHz FT-73R. Whichever you choose, you benefit from incredibly small packaging. Take a look at the actual size photo. Aluminum alloy cases that prove them selves reliable in a one-meter drop test onto solid concrete. And...

In this case, L 2952 x 0.5 902 1.64 inches. This result is very close to the length determined by the scaling method, and the scaling method is simpler PRISM Electronics has developed a low-cost accelerator board for IBM PC, PC-XT, and PC compatibles. PC-BANDIT resides in the computer's current 8284 clock chip position to provide additional clocks with its own clock IC. No expansion slot is required. The 0.8-in x 3.1-in board uses software to toggle between speeds, and it is compatible with...
