If you are a serious contest op you should not be reading this ‹ get back in the chair and work some more stations. I have been asked to operate 160m this evening by several Caribbean stations. Since they are all multi¹s they may have time to read this. I will make an effort to be on starting at

I may have worked only 10 S&P last night. When it is a struggle to work WY,UT,MT and WA from ID you know something is not right. I did manage one NY, IN, OH, IA, and ND but could not even hear the ID station that worked the MT station just before me. I complement the NY station [ note I am not us

Is no one going to suggest that a ³gyrator² should be put into the circuit instead of an inductor? There was a W3 who had some of the diodes for replacements. They are surface mount and small! Obviously, one wants them to have a very low conduction threshold voltage. I suspect Tom can suggest some

I am sure [or at least I hope] I could sort through the information available in books and on the web for the answer to this question, but maybe someone reading this reflector can give me an 'instant' answer [preferably correct]. I intend to use a powdered iron core toroid as the form for an induc

Joe, et. al I am quite certain that there will need to be different sense antennas for 160m and 630m. I would not be surprised if we did not also need bandpass filters for each of the bands as well. As I recall there were several circuits in QST using a single analog Devices unit to measure RF i

A trivial point in this discussion, but of some consequence in assessment of data, the average is almost always NOT the 50% point of a population. The Median is the midpoint -- that is 50% of the population is above and 50% below the Median. The Average [or Mean] for a population is very dependent
