1. Is it normal behavior to lose saved memory values of tuned positions. I checked other spots and nothing is saved on the entire 80-meter band — I mean, I had high-SWR on all of my 20 KHz sections.
It doesn't sound like normal behavior, I imagine they're in EEPROM or something like that.
2. Or, is there something else happening. I have heard that the K3/KAT500 combo gets messed up if the K3 comes alive before the KAT500. Is that possibly what happened here? I was not in the room when this happened so I am assuming that power on startup was a race and I am thinking that the KAT500 might be first but I don’t know.
I once fired up the K3 ahead of the KAT500, and while it didn't lose its mind, things didn't work right. Removing power [really pulling the plugs] and restoring it with KAT500 ahead of K3 solved the problem. I'm pretty sure that the K-Line is like everything else in this house that runs on electricity, "off" isn't really all the way to "OFF."
3. I am assuming I have to reprogram all my memory locations for all three of my antennas (80/40/30 meter dipoles).
It is human nature to assume the worst when often it's a lot simpler. I'd try the "real OFF" thing first and re-power in the right order. Our low impedance/hi-current 21st century gear uses very large capacitors so give everything a chance to discharge. The KAT500 Utility will let you look at the current L-C values in the L-network for wherever the tuner thinks it is tuned, you might try moving through a band and see if they change as you QSY ... or are perhaps all zero?
The Pineapple Express is moving into NorCal tonite, we're on a 69 KV tie line that runs through our pasture between two hydroelectric plants and we don't lose power very often, but just in case I think I'll pull the plug on everything before I head for bed.
