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

Knocked up a home made #youloop - otherwise known as a #moebius antenna today. Surprised that it works at all for such a small circumference - about 220cm. I've an #airspy HF+ Discovery, which is sensitive enough for it. Learnings: 1. It's impossible to solder the shield of Screwfix RG6 satellite coax 2. Use 2 small boxes for the connections. - I didn't. #hamradio

Usually the UHF SatCom satellites has Brazilian truckers and Russian national anthem, but it has sometimes surprises. Today there was medical consultation, in English, over two-way radio. I only heard the other side.
There was even on-hold music! π
Received with #airspy Mini and discone.

#Airspy's SDR# 1911 released, with many DSP, UI and performance enhancements. airspy.com/download
21st place for 24hrs (Airspyplus) on PSKReporter monitoring only FT8 with an #Airspy HF+ and 75ft long, 25ft high inverted L antenna. 12,846 calls, 4912 stations and 108 countries. ADIF from pskreporter and mapped with #GridTracker. Location is east of Houston Texas two days ago on the 21st.
And look, the #sdrserver service for my #AirSpy HF+ Discovery is still running.

Noise pollution is a real problem all over the EM spectrum, not just the visible and audible parts.
I'm bringing this device to a friend's to help him track down some EM noise at his place. Since the antenna is hanging on the wall, the SDR is here, too--which means the #RaspberryPi is within a few feet...

@alex Far out! This is amazing coverage!!
Thanks so much for taking the jump into #Iridium #acars with the #airspy R2 #sdr
I wonder what antenna and computer you are using. Each of the three main parts are so critical for Iridium decoding.
Let me know if you want to feed the site or need a hand feeding @airframes or want to add your map to the master map.
Just amazing day.
We hit +30K #Iridium #ACARS messages.
I think my first day hit about 500 messages.
Amazing how the global network of ground stations grown the past few years.
Most stations are using the #airspy R2 #sdr
I'm working on adding the messages to the site search and all the tables on the site.
Usually the browser tab crashes, but this one has been running for about 5 days now.
Right now we are decoding three sondes at once with the #airspy R2 #SDR on the #RaspberryPi 4
Running the amazing radiosonde_auto_rx by @vk5qi and the team.
Hello, 160 Meters CW!
CQ contest! CQ contest!
Receiving in central #Ohio on an #Airspy HF+ connected to a tiny 9:1 balun and 37 random feet of wire strung up in my house, along the ceiling. Audio is sent from SDR Console via virtual audio cable to CW Skimmer that can do hundreds of decodes at once.

An #Airspy HF+ and a #Youloop antenna is very portable, and gets you very broad frequency receive coverage.
#Nooelec has some fun SDR parts too.
The ARROW club is doing a group build of a "tape measure Yagi" antenna, optimized for 2 meters and very directional. That's a transmit and a receive antenna, and when I get it built I hope to take to to the top of a parking structure and point it at repeaters far away.
