Has anyone got experience using Steve's (WA1QIX's) Improved three diode limiter? I'm thinking of adding this to my Home Brew 833's to tame the potential of excessive negative modulation. I have lots of audio power available and seem to run into over-modulation if I do not very carefully adjust the transmitter. I'm repairing my VoluMax today. It has a bad pot that tends to re-adjust the audio drive to the transmitter for me. But even after fixing that and carefully adjusting everything avoiding 100% Neg. will still be an issue. I'm wondering about the results of using the diode limiter here? Will I be able to adjust the transmitter for something like 120% positive & 99% negative? Like I said, 833's make the audio with a Peter Dahl BC-1T Mod transformer & Heising setup. I'm assuming that this circuit will work on the heising reactor just as well as the mod transformer. I'm considering this:
