Talk about "snake oil" this dissipation brush thing is nuts. A bunch of sharp wires on the top of an tower is supposed to prevent lightning? If there is a high potential between these wires and the c

A little more about snake oil. About the only thing you can do to control where lightning is going to strike is to attract it, more or less. A lightning rod or one of these dissipation brushes produc

I have used 3 MFJ analyzers. Two have failed one was a fault in the analyzer the second was an accidental application of reverse supply voltage ( picked up a reverse polarized 12 volt plug by mistake

Analyzers have been improving over the years. The ones had were the first ones off the production line. This last one is fairly good. If they used better detectors and bridge circuits they would be m

Interesting question. All radios put out spurs,harmonics, splatter etc. It is a matter of level. An example; years ago I heard a lower sideband signal on the upper part of 10 meters and waited for an

You CAN hear 5 Hz tone burst. Same as slow CW. He obviously is using his BFO and thus is hearing burst rather than a 5 Hz sinusoidal signal. 73 Bill wa4lav To: <tentec@contesting.com>

Because you can hear both stations does not mean that they can hear each other. This is one problem with the secondary allocation concept. One Primary station sending a signal to another may have goo

The best we had until Collins introduced the noise blanker was noise limiters. But usually they produced some distortion. A few had a means of self adjustment so that they would not produce much dist

Switching at this higher IF frequency is difficult. The resistance of the switch must be very low compared to the source resistor's value and have low inductance. A tiny reed switch perhaps would wor
