This Chart of Radio Symbols would make a nice
wall poster for your office, lab, or Ham shack. It has a nice vintage look to it

it is a true vintage relic. Although it would look great in its gray scale format,
importing it into a graphics program and adding a little color would really jazz
it up. A bit of brown would provide an aged sepia look, or you could go all out

When designing a receiver or transmitter using
discrete components rather than connectorized components or packaged integrated
circuit, where the interfaces are at or near 50 + j0 Ω, adding
frequency selectivity beyond that provided by the generic response requires inserting

Achieving clean oscillations above about 300 MHz
(1 meter wavelength) from standard glass and metal
vacuum tubes is difficult due to interelectrode capacitances and self-inductance

magnetron, and
ring oscillator tubes during World War II years. The UHF
