Simulation of regenerative receivers

At the Yahoo Group called regenrx, I got into a good discussion with another user about simulating regenerative receivers, a topic I am particularly interested in. There seems to be a small number of people doing these sorts of simulations and there are various tricks needed to gain insight into the behavior of the almost- or barely-oscillating detector. I've picked up a few tricks here and there, but I felt it would be helpful if all the relevant information could be gathered in one place.

Thus I created a new Yahoo Group called regenrx-simulations. There are already a few working examples posted showing AM detection and CW detection, including regenerative amplification and AF detection. Other examples include frequency determination via FFT and AC sweeps, determining the threshold regeneration level with parameter sweeps, and frequency shift with regeneration adjustment.

Feel free to stop by and have a look!
