an interesting "twist" for AM modulation.
using the "WFM" module to generate the carrier and the "SSB" module configured to "DSB" to generate the AM modulation.
AM modulation performance is way way better than just using the "AM" module alone.
i can clearly see the spectral efficiency is way better using this method of modulation.
carrier = 15w, PEP = 60w

A slight bit of audio at 2135 utc, 22 Mar. Tough to get hardly anything, but the signal is showing up well on the monitor.
