Repeater Info

Long time since we last wrote to let you know about the FM scene in UK and the rest of Europe. It also gives me the chance to thank you for the copies of 73 (unfortunately postal delays mean that 1 only received the May copy today). Since the 1ARU meeting last May, the FM channels are beginning to get really used on an international basis. The main activity is between 145,500 145.600 at 25 kHz steps. As to the repeaters, 1 can only give you definite info on some, Belgium-9 .planned, awaiting...

Low Cost Frequency Counter

TI here are still a few hams who have not built a digital counter, due in some cases to misconceptions regarding the complexity of digital devices. The counter to be described is about as basic as a counter can get, is very inexpensive to build, and will count to above 30 MHz. The readout is in decimal form, using 7 segment incandescent Minitron displayDevices used for the digital section of the counter are all SN7400 series. Data sheets on these integrated circuits are available from many of...

Simple Qrp Transmitter

Simple Qrp Radio

This article will describe a two transistor transmitter that is not difficult to build, and can supply up to one watt rf output for the QRP or portable sportsmen. The transistors are not excessively priced and are very reliable even though operated beyond their ratings. The use of an unusual type of keying provides chirpiess keying with a negligible backwave. The transmitter operates from a I 2 volt source making a car battery or iantern batteries ideal for portable use. With this...

Oscar Operations Summary

A Guest Editorial by Perry A Klein K3JTE OSCAR 6, first in the series of AMSAT-OSCARB missions, con tinues to operate satisfactorily after seven months in orbit. During the first week in May, the operating schedule was modified making the translator available for communications on Thursdays, Saturdays and Mondays, Greenwich Mean Time, and OFF on other days, he purpose of this change was to subject the nickel-cadmium battery to shorter, more frequent charge-discharge cycles. This procedure...

Sbe Sidebander

The SBE SB-50 SIDEBANDER 6 is an all solid-state 6 meter upper SSB and AM transceiver. Frequency coverage is from 50.050 to 50.280 in 23 switched segments of 10 kHz each. The heterodyne oscillator is a frequency synthesized arrangement of 10 crystals combined with the 7.8 MHz j-f to produce the frequency range mentioned. One switch selects the proper pair of crystals to provide any frequency within this range. To cover the frequencies between the 10 kHz points, one of the crystal oscillators is...
