Quement Model SWB-2 Dual Meter Standing Wave Bridge

The new Model SWB-2 is a convenient, compact, dual indicator device for use in the amateur radio station to check the operation of the antenna load to the transmitter. For VSWR measurements, this unit uses the dual bridge method of comparing simultaneously the power supplied to and reflected from the antenna system. Continuous monitoring of the transmitter output as well as continuous monitoring of the reflected power is possible by having the instrument in the transmission line at all times.

Price is $15.95 from Quement Electronics, 1000 South Bascom Avenue, San Jose? California.

The Transistor Radio Handbook

Editors and Engineers, the publishers of the famous Radio Handbook, have just released a transistor handbook that should be on your shelf. This was written by Don Stoner and Lester Earnshaw, whom you should know by now. The book was obviously written for the average amateur for it will not strain the average intellect. It starts with the usual discussion of holes and the like, and rapidly goes on to the practical applications with the basic circuits and a myriad of construction projects.

The book covers audio amplifiers, compressors, modulators, rf amplifiers, detectors, AGO circuits, oscillators, receivers, from a superregenerative detector right up through a complete superheterodyne. There are simple and complex receiver projects, converters for VHF; product detectors, crystal filters, and transmitting power amplifiers^ linear amplifiers, VFO's, etc. Power supplies are covered too, in depth, with do-it-yourself examples of each type.

The book is only $5 and is available at most good parts distributors.
