    1. Vol 1 AM, SSB & the Voice Modes — Vol 1: Grabbing the Amplitude Knob Morse code is amplitude modulation with only two settings. Turn the knob smoothly instead of slamming it, and you get AM — plus a pair of mirror-image sidebands that nobody asked for and everybody has to pay for.
    2. Vol 2 AM, SSB & the Voice Modes — Vol 2: Throwing Away Two-Thirds of Your Signal Suppress the carrier, delete one twin, and SSB gains 9 dB — not the 6 dB you usually read. And the famous explanation for why we use LSB below 10 MHz turns out to be arithmetically impossible.
