An auxiliary antenna tuner for loading the mini-mi+ter into a random length wire. The L C ratio is selected +o resonate on the desired band. The first transistor in a radio receiver is very likely to take too much overload voltage when a medium or high powered transmitter is being used. Back-to-back diodes connected across the coaxial input jack to the receiver or converter offer considerable protection, but still enough signal gets i hrough to sometimes cause a deterioration of the...

With the advent of incentive licensing, lots of our long time phone operators are coming to the realization that CW is a necessary evil. It is more than coincidence that the 75 meter round tables seem to drop in numbers when the W1AM code broadcasts are scheduled to begin. For some, the return to CW is a temporary thing and simply a means to the end of achieving the higher class license. For others, it is a discovery that CW can be fun after all. For the straight key man or the bug artist, the...

Creates Irregular Fields Along Earth

UTTLE RE-flADiATtON FIELD RETURNS TO CREATE FIGURE 8. Horizontally polarized radio wave, top, interacts with the surface of the earth to produce irregular fields and also reflects, so that wave is unable to just skim the horizon. Vertically polarized wave, bottom, has less interaction with earth's surface and consequently provides better ground-wave coverage. Zero-angle radiation is also easier to achieve due to absence of multiple reflection. UTTLE RE-flADiATtON FIELD RETURNS TO CREATE FIGURE...
