Asterisk because the article is nearly two weeks old at this point. NOAA 15 is due to be put into an “electrically safe mode” including turning its transmitters off tomorrow 12 Aug 2025 and NOAA 19 is to have its transmitters turned off on 19 Aug 2025.
RIP IN PIECE to the satellites that got me interested in radio waves and all things SDR. NOAA 18 bit the dust a few weeks or so before NOAA declared the remaining two EOL and NOAA 15, and 19 are fast approaching their end too. They have lived far beyond their intended lives and have been replaced with a bunch of stuff in the X band which is all microstrip and horn antennas, and high frequency stuff that I just dont really have the time to get into right now and besides, all the SDR’s that pick up that stuff are all thousand(s) typically and require actual programming knowledge beyond my ability to cut n paste. DIY antennas for that frequency band take more effort and talent than i have to make. Probably more money than I have too.
So anyway RIP to some real ones. If you are into that sorta stuff, better get that last pass or two in before they flip the switches. Im going to take my QFH and mount it on a giant wooden pole and go out in the road and record one more pass with an SDR and an old Android phone I have kicking around in my desk drawer for old time sake.
decided to include saveitforparts’s video about it which is where i learned about it originally, but posted an actual article about it too.
