I thought I just saw something like this listed here in the last day or two. Might be gone by now, though... Best thing was - they were FREE!!

If not, consider FM'ing the transmitters, and installing some sort of audio processor designed to do the job of clipping and HPF'ing that fits the situation. The AP-50 is one such animal. Most commercial equipment audio chain in good from only 300 to 3000 cycles; it won't pass PL and it won't pass the high-end audio that the voter relies on to properly vote. The phase modulators that most of this equipment utilizes won't properly follow audio that is recovered from the discriminator, and is why I choose to install a real FM modulator in the radio set. A better sounding, better working radio will result; one that is transparent to the system. I have never tried to FM a EXEC II; we've always used MASTR II's for remote satellite receiver - link-back transmitter combo's, but, I don't see why it can't be done. Kevin Custer
