Breaking news.
Power outage and the Laguna Fire is 6 miles west of my house. Car is packed with only 1 Radio. If my home gets smoked then it's the end of my boat anchor collection.
An inconvenience but not the end of the world.
There was a popular song many moons ago by Johnny Cash called Ring of Fire. Well, there is a Ring of Fire around the Los Angeles Area. The latest is the Hughes Fire near Lake Castaic about 40 Miles NE from me. As usual a raft of PSPS texts, emails and even phone calls to expect my power to go down for the 4th time in two months.

This fire situation is great political fodder for what's his name, but the reality is that I keep nothing in the refrigerator, and I have my go stuff at the front door. But the Hughes Fire is different -- I can smell it, whereas the other fires in the ring were not smelly at this QTH. At 9000 acres burnt that comes to about 14 Square Miles. [9000*43560 / (5280^2) = 14.1 sq miles]
My battery is charged so I have Cell Phone and Laptop charging capabilities. In many respects having the XYL in a Board and Care facility is a plus as her location has had less PSPS shutdowns and there is staff there 24/7 and they have back up Oxygen systems. It would be impossible to care for her here at home with the power off for three or four days. Bright spot: Rain is expected this weekend.
I have simulated a J310 JFET general purpose amp stage using LT Spice. Indeed, the results looking promising and so a bit more work toward a low power consumption emergency rig. Too bad I keep having to delay things because of the PSPS situation.
This simulation is just a starting place as the simulation of the 500 Ohm filter is just a plug circuit to see if this could work. More simulation time is needed to accurately represent the actual 9 MHz filter and then see the gain across the module.
Them that know can make it go.
