Tom Anderson explains radio frequency electronics (RF). Elecia and Christopher try to keep up. We also took a detour into bass guitar electronics.

One confusing jargon part is that radio power (in dBm) is discussed as though it is voltage. For example, 10 dBM is 2V peak-to-peak; there is an implied 50 ohm resistor in the P=V*V/R calculation. The the wiki for more about decibel-milliwatts.

Tom talked about dollhouses, aka Smith charts (wiki). (We also talked about Bode plots (wiki).)

Light travels about 1 foot in 1 nanosecond (11.8 inches, 30 cm). Admiral Grace Hopper is well known for giving out nanoseconds.

The guitar company Tom mentioned working with is Alembic.
