Geeze! What is Mike up to now!!! Cool stuff, like Amateur SSTV from MIR. A 2 Meter antenna for bicycles. Working the AO-27 satellite portable.
The radials are buried at the base of the vertical antenna. The radials are ¼ wavelength long of your lowest frequency used. Please use at least 12 radials as a start. They should be buried 6 to 12 inches in the ground. Like all things in the world of Ham Radio this is subject ...
The measurements are very easy requiring the input and also the output of the circuit under test being connected to the noise figure meter. The test instrument is set up, the test is initiated and results are provided. Very simple, but accurate test. Spectrum analyzer noise figure...
One of my earliest memories is the sight of the glowing white-hot graphite anode of the Eitel-McCullough 35T triode in my father’s ham radio transmitter. At about three or four years old, it was certainly the brightest light I had yet seen. His whole rig was “breadboarded”…the compo...

This perspective has as a consequence that from a perceptual point of view the past can be defined as the sequence {… S-2, S-1}, the future as the sequence {S+1, S+2,…} and the present as the state S0. At this point it is important to emphasize that these states are perfect...

Accordingly it is quite acceptable to use an antenna tuner or antenna tuning unit close to the transmitter and not at the feed point of the antenna.It is worth placing a VSWR meter in the line to monitor the actual level of standing waves seen by the transmitter. Note: a separate meter ...
