Be sure and tune in when The Mighty KBC's Dave & Eric rock the airwaves soon at 0000-0200 UTC (Sat. 8-10p EDT) on 5950 kHz. A minute of MFSK64, with this weekend's musician birthday, at 0130 UTC. And later in the 0100z hour some SSTV with Peter John's "DX Headlines"

I never publicly comment on political matters because they are usually irrelevant to my work of providing hurricane data and forecasts to people in my personal capacity. Today though, it is highly relevant, and as a member of the meteorological community, I am angry. Planned or ongoing bulk workforce cuts would irreparably harm the National Weather Service, NOAA, and their scientists who save innumerable lives by warning people in advance of tornadoes, hurricanes, wildfires, tsunamis, blizzards, and other life-threatening hazards. Many of you reading this may knowingly or unknowingly be alive today because of their work, or know someone who is. As a direct consequence of wounding the NWS and NOAA, the public would be less safe. My personal mission to bring hurricane science, data, and forecasts to the public would not be possible without the weather observations, doppler radar stations, computer models, hurricane hunter aircraft, and weather satellites provided by NOAA and the NWS. Your favorite weather apps, TV meteorologists, and private weather companies would also be unable to function without this data or the civil servants who live and breathe it to synthesize it into public safety information. All of these benefits cost each taxpayer the equivalent of a few cups of coffee per year, and surveys show most would be willing to pay much more. The American weather enterprise saves many, many times more money than it costs to run, making it one of the biggest bangs for your buck in the government. The impact of quality weather forecasts and infrastructure on society is multiplied many-fold by preventing economic disruptions, keeping public transportation efficient, and providing lead time to prepare for and mitigate disasters. Most importantly, it saves priceless lives. Careful, long-term plans to streamline or reorient the weather enterprise in an evolving world are not bad, but *this plan* is insane. A feverish rush to take a cleaver to this workforce is self-destructive and dangerous to Americans who rely on the services they provide. It also cuts off the legs of young, passionate scientists who represent the future of meteorology in the new age of AI and other emerging technologies -- the very people we need in the field right now. As a part of this community since the age of 8 when I began analyzing hurricanes with dial-up internet, I am heartbroken and concerned by what appears to be planned or already in motion. It also directly impacts my friends and family. I cannot be silent, despite knowing I do myself no favors by speaking out. I ask you to join me in advocating for @NWS and @NOAA if you value their work or the work that I am able to do because of them. There are many ways to make your voice heard. That's all for now, thanks for reading.

@SWRadiogram It's Thanksgiving eve and time to put out holiday lights! We'll start with an rescaled image from today's broadcast, 15770 kHz @ 1330-1400 UTC, decoded in northern Florida, USA. A bit of multipath mixed in with the data stream helps to make things bright...

I don't usually re-Tweet others' posts, but when I do it's usually Airspy's Black Friday giveaway Tweet! Hopefully there's also one on BlueSky...
The first winner will be picked tomorrow. #Retweet and #Like to participate!

@SWRadiogram Images 5-8 from the broadcast. A fair amount of 60/120 Hz hum modulation has settled into the signal. I'm tuned in using Airspy HF+ --> Pi 5 Spyserver --> SDR# v. 1921 software.

@SWRadiogram Saturday 7780kHz reception in northern Florida, USA. Good reception of WRMI's signal here. Some interference on the lower side of the signal, but it doesn't appear to be causing troubles with MFSK64 modulation. Images 1-4...

@SWRadiogram And the final two. WINB had a strong signal here, but there seemed to be a higher than normal amount of background noise. Receiving with Airspy HF+ and 64-bit beta version of SDR# which is using MS .Net v9.

@SWRadiogram Saturday's broadcast on 7⃣7⃣8⃣0⃣ kHz. 2300-2330 UTC as received in northern Florida, USA. Using Airspy HF+ & SDR# with noise reduction off (L) and NR on in Data mode (R). Using custom filter didn't seem to help. These are about the best I received.
