It turns out that on that evening KENS enjoyed a catastrophic failure of an Intermediate Power Amplifier power supply shelf. This first dropped our power to 25% and then zero as we struggled to keep a signal on the air. We went to our low power auxiliary for a short time while reconfiguring the main transmitter to operate at 50% power.
About one week later we began to see fluctuations in CPS power to the site, where it looked like the utility was switching KENS to a different grid or transformer, one phase at a time. This causes the transmitter to shut down each time there is a hiccup on even one phase for less than one second. While that problem was self-correcting, we lost our main transmitter again on Thursday afternoon, August 4. Took about 45 minutes to shut down and re-start the main while we were on the auxiliary again. KENS remains at 50% power. We expect to install new power supplies on Monday or Tuesday and return to full power.
As to the strong tropo conditions cited by WA5IYX, that may cause some interference to fringe viewers and those with inadequate antennas. I have had several calls from viewers in the Canyon Lake area who are unable to see us at certain times of day.
