It is common knowledge among radio amateurs that a 40m center-fed half wave dipole antenna will work very well on 15m. That is because center fed dipole antennas,
An ideal long wire antenna is one which is several wavelengths long. But that is not practical for most amateur radio operators. Sometimes it is also called as
Yesterday evening I tuned to 20m with my shortened end fed half wave antenna mounted using 3m PVC/CPVC pipes on my first floor terrace. To my surprise several
I used to work on 80m in late 1980s when the solar cycle started going down and propagation on 40m started deteriorating. I made necessary changes in my
We have discussed tuned radio frequency receivers and superheterodyne receivers. Among superheterodyne receivers we have seen both upconverting superhets and the conventional downconverting superhets. Another type of radio
Stability of an oscillator is the degree of uniformity of frequency of the oscillator when measured over time. Frequency can change with change in conditions like temperature, load
