having a lot of fun watching the air traffic. i loaded dump1090 onto a debian machine, plugged in an RTL-SDR usb dongle, a hacked coax 1/4 wave vertical, and bam, we got all sorts of fun info about the planes flying over. here’s the raw dump from dump1090
then, using mono to run VirtualRadar, can see from other machines browser live updating with tracks, and net lookups of the tail numbers. i can only “see” about 10-30 miles out, so very lucky to be looking at it just the right time…..
…..and then along comes SOFIA, the NASA flying telescope. Yes, they open a door on the side, the back section is de-pressurized, so to have a clear view of the heavens. the Ultimate Convertible, no?
and a double check against the pro’s,
so, who read all the way down here, and want’s to hear about the CHP Ghost C-130 flying circles over Folsom Lake?
soaring record temps across the western US, guess what kids, the Rex Block is Back. 2 incoming systems have bounced already, and looks like the next will have a hard time getting over the high pressure too.

the wrap around results in some serious vortex activity on the east coast, here can see the curve over washington state over B.C., dives back down into the midwest, and spills out over the atlantic, creating an intense low pressure spiral. That should have been rain for us, but the human heat is already summer levels.

my satellite reception is plagued by noisy power lines nearby. but every so often, the pass times when the grow-lights up the road are not on, and the cloud tops are cold enough, that the color enhancement mode works. expect tornadoes when this upper level cold trough makes it over the ridges.
notice how the signal was clear enough only for 20-45 latitude. also of note, the system cloud line extends from well south into Baja, all the way north to Alaska.
perfectly clear night last night, made for brrrrr and easy view of new snow on the IR channel. all the white you see on west coast and over to the rockies is snow on mountains, not clouds. (well, some clouds of course, but mostly snow). something haven’t seen in a long time, and hopefully more coming with the front off to the west..

from an RF transistor datasheet was just casually perusing….my sense of humor in bold.
1.High Temperature ; This product might have a heat generation while operation,Please take notice that have a possibility to receive a burn to touch the operating product directly or touch the product until cold after switch off. At the near the product,do not place the combustible material that have possibilities to arise the fire.
2.Generation of High Frequency Power ; This product generate a high frequency power. Please take notice that do not leakage the unnecessary electric wave and use this products without cause damage for human and property per normal operation.
3.Before use; Before use the product,Please design the equipment in consideration of the risk for human and electric wave obstacle for equipment.
so, my weather satellite pics where getting worse since the rain came back. pulled the antenna down, cleaned all the connectors, like cleaning the lense on a camera i suppose. the corrosion becomes a semi-conductor, and can rectify RF, attenuate the signal, basically make the connection a semi-connection. doesn’t take much loss to not hear at all when listening for radio 870km away….
and now that the connection is clean, can see the coming cold front, Thanks For The Rain!!!

equinox is still a few days away, but this almost 1″ of rain sure felt like a winter cold front. hoping it’s a “good start” …..
finally, a little bit of wet. so far maybe 1/8″, ground is actually “wet”, no puddles yet, but close. yesterday’s pass saw it coming….
embedded shortwave brought drizzle this afternoon. hoping that will dampen the lightning that will follow when this moves onshore. i think i’ll bring my mudboots to that thing in the dessert…..
