My latest video shows an upgrade to the CFT1 5-Band CW QRP transceiver by adding the "half-upgrade" kit from KM4CFT that adds an internal speaker, but with the added plus of an internal audio amplifier:

Finally got around to doing another transistor tutorial video. This one talks about the input and output impedances of a common emitter amplifier:

Here's a followup video that discusses cascading CE amps, and how an emitter follower mitigates loading effects: youtu.be/pAUYDPwCMj4
