Hmmm. I had one of those Koolertrons until I destroyed the output. It does AM and FM modulation using the channel 2 as the source, along with several other modulations. I currently use a FY6800. Very similar. Output amplitude goes down to .0001 and up to 20 volts at some frequencies. Not sure if the output is actually that low as I have no way to actually measure that low. However, it seemed to work as a direct connection to the antenna without activating AVC. I am now using morzh's circuit to protect the input from spikes. It's a 60mHz unit. I use the harmonic to work in the FM band.
