Principle) to estimate the total mass of the universe, assuming that local forces are the result of this interaction. Einstein was aware of this possibility, and saw that his universe would tend to spread outward or fall inward rather than stay put, because any tendency to fall inward, for example, would increase the inertial, and therefore the gravitational, forces between the galaxies, thus increasing the speed of collapse. Flis universe was like a coin balanced on edge. He introduced a...

Government At It Again

A newspaper clipping sent in by WB2EQG was so preposterous that 1 had to read it twice to be sure that it wasn't a joke in poor taste. It seems that our government has such a desperate need to spend more and more money that they are now asking for recommendations on mandatory safety standards to prevent CBers from electrocuting themselves by leaning towers against power lines. This is being done by the U.S. Product Safety Commission, 1111 18th Street NW, Washington DC 20207. Granted that some...

This made possible the prediction of the monthly values for Cycle 21 the predicted maximum value falls in early 1980. Alsor an analysis showed that the three largest cycles had the steepest emergencies while the smaller cycles proceeded less steeply from the minima....

Illustration Of Modified Ohl Method Of Prediction

Most predictions to date have indicated a low sunspot value (120 or less) for the present cycle, Cycle 21. One of these, however, predicts a smoothed sunspot maximum value of 154 to occur in early 1980 which is considerably higher, and earlier, than the others. A high correlation between the value of geomagnetic activity during the years immediately preceding solar minimum and solar maximum reached during the next half-cycle has been found. If accurate, Cycle 21 will be equivalent to,...

Impossible Feat

The biggest problem with tuners is getting them tuned up. With three knobs to tune on your transceiver and three on the tuner and ten seconds to do it (see the warning in your transceiver manual) that's 1Ys> seconds per knob. We have a better way a built-in 50-ohm noise bridge that fets you set the tuner controls without transmitting. And a switch that lets you tune your transmitter into a dummy load. So you can do the whole tuneup without going on the air. Saves that final cuts QRM.
