A follow-up to the situation. I purchased a PWRgate PG40S. On one side I have a marine battery. On the other side I've got an Alinco DM-330MVT. In the middle is the KX3 and the Flex. Only one has an antenna at any time.
I added a line isolator right below the BALUN of the OCF and another one right at the rig input. At this point there is no difference in the noise level on the KX3 when comparing internal batteries vs the power setup described above. The Flex is also not showing anything of concern on the waterfall. I was (and maybe still am) a little skeptical about both the Alinco switching power supply and the PWRgate which I think is just the switching portion of a switching power supply? So far they do not seem to be generating noise. I'll have to give it some time to see if any snakes come crawling across the waterfall. Remaining work... I'm calling things 80% done and getting back to normal operation. I want to add some more clip-ons to power cables as soon as I can remember where I put them all. I need to tear into the RS-50 and see if I see anything obvious and if not, dig deeper with the o'scope and meter and actually do some troubleshooting. If I get it working right then I have a good backup or loaner supply. If not... who knows. I also need to continue reading the RFI document. There's a ton of information in it and I'm working to actually understand what I'm reading instead of just using it as a cookbook. A more balanced antenna - even a Hex Beam - might be on the wish list. Thanks for all the help and guidance. I'm feeling pretty good that things are working well. The QRP Foxhunt is tomorrow night. I hope to be able to blame my anticipated poor performance on atmospheric conditions and not equipment noise. 73!
