What's Coming Up in the March/April Issue of QEX

The March/April issue of QEX is out, and it is full of theoretical and practical technical articles that you don't want to miss.

In this issue, Milt Cram, W8NUE, and George Heron, N2APB, describe the design and construction details of their "NUE-PSK Digital Modem." The authors provide complete technical details as a companion to their March QST article. Cornell Drentea, KW7CD, presents some schematic diagrams and circuit descriptions for his "Star-10 Transceiver," in Part 2 of this series.

Jack Smith, K8ZOA, provides an interesting look at carbon composition resistor aging as well as inductive and capacitive effects of other resistor construction types in "Carbon Composition, Carbon Film and Metal Oxide Film Resistors." Contributing Editor L. B. Cebik, W4RNL, looks at several impedance matching options for modern HF and VHF beam antennas in "Antenna Options."
