A salutary tale

I thought I'd taken precautions by depowering and unplugging my SDRs before transmitting at around 50W on HF the other day, but I appear to have fried the input of my Airspy Discovery HF+!

In the vain hope that reinstalling the firmware might help, I tried to reset it and flash the device but it could not be found on the USB input.

So it's now also bricked! This was the most sensitive little HF SDR I had, so none too happy today

Looks like I've found the #BBC at 44.241 MHz?

SDR Firmware

I just spent three hours trying to flash update my Airspy HF+ Discovery. Followed the instruction to the letter but failed every time.

I later found that the Airspys can only be flashed from a Windows 10 machine, not Windows 11! Luckily my older second PC is still on Windows 10, so I was able to un-brick it! So happy now!

The PiZero 2W spectrum recorder runs for 7 hours on two 18650s & a step-down 5V converter (which doesn’t seem to add measurable noise on HF). And of course the batteries are hot-swappable as the unit has its own small UPS battery. The only limitation is the amount of free space on the MicroSD card #PortableSDR #SDR #HF #Shortwave #SpectrumCapture #SpectrumRecording #AirSpy

Rádio Nacional da Amazônia on 04/12/24 at 2200z on 11780 kHz. Captured with the battery-powered Pi Zero 2W, AirSpy HF+ and 2x6m dipole in a local park. #PortableSDR #SpectrumCapture #Shortwave #HF #DX #AirSpy #PiZero2W #PiZero

My AirSPY HF+ installation is working again under OpenWebRX+ v1.2.61 after I followed the instructions at https://groups.io/g/openwebrx/topic/103545886 to change /etc/udev/rules.d/52-airspyhf.rules

The upstream issue is https://github.com/airspy/airspyhf/issues/46 and open for quite a long time, udev rules appear to be hard to get right portably.

now some hashtags in the hope I can find this again if I need to find it

Honest Ali sent me his version of a miniwhip antenna. My setup is #AirSpy Mini with SpyVerter, LiFePO4 battery and a fishing rod.

There are heaps of RFI in the city, but some bands are clear. Not too bad...

SatDump
A generic satellite data processing software.

Decode various satellites with SatDump using your Android device and compatible SDR. Receive #NOAA APT & #DSB, #LRPT, #HRPT, and other satellites, including geostationary ones like #GOES, GK-2A, on-the-go.
A good use case is receiving 137Mhz weather satellites conveniently.

Supported SDRs : #RTL-SDR, #Airspy, Airspy HF, #MiriSDR, LimeSDR Mini

Playing with my #AirSpy DiscoveryHF+ #SDR receiver and passive "YouLoop" magnetic loop antenna

which is just hanging from the curtains in the living room

but I'm picking up #FT8 on 40m all over the US.

Earlier (before the sun went down), I picked up some 10m stations from Japan and Korea

#Radio is magic

Getting a great spread of ranges from our #radiosonde auto_rx setup with the #airspy R2 #SDR right now.
Running an odd Amazon antenna, #Uputronic LNA, Raspberry Pi 4. Details on my GitHub page. Link in bio.

The QSL card from RadioTaiwan DEU arrived. Thanks! I was #SWL 'ing special 2023-07-09 German language programing on the go with #Airspy HF+Discovery connected to my Android tablet.

Im testing out using an #airspy mini #SDR vs the #RTLSDR v3 on my ADSB system.
I'm all that hard core on #adsb but its nice to corollate the #ACARS testing I do with ADSB data.
As usual with aircraft data, it needs to soak for a week before you can really make any conclusions.

Was a bit surprised to see this Osprey V22 fly past on the map.

Aha! #radiosonde #autorx station caught a balloon all the way up in Bakersfield! I'm curious if that is due to some kind of ducting or if it was just in the right place. #hamradio #sdr #airspy

#Airspy has significantly more capability than an RTL-SDR! #sdr #hamradio #radiosonde

Listening to baseball on the radio. #WLW 700 kHz via an #Airspy HF+ and a #YouLoop antenna. Transmitter is about 200 miles direct from here, nearly due south along I-75.

There is some noise under the signal but it's very copyable.

Cubs leading the Reds 14-6 bottom of the 7th inning.

Here is a snapshot from #GQRX. I have stations labelled with the baseball team to listen to.

I get a #telegram bot alert for each #radiosonde launch my station picks up.
(I tap into the chasemap #json with #nodered )
It still blows my mind how well the @vk5qi #auto_rx works with the #airspy R2, good #antenna and #lna
