I am really impressed with the RTL-SDR V4 HF reception. I have been listening to 12m (24.915 MHz) #FT8 all day with a bad antenna.

#hamradio #rtlsdr

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.

Having fun with my new Raspberry Pi 4 and a software-defined radio.

I know now which cars my neighbours drive and what their tyre pressures are, I know that their house burglar alarm is working, and I can see the depth of oil they have in their domestic oil tank!

My at-home repeater project is shaping up to be a monster.

Repeater is three radios. One to rx/tx from my antenna, my qrz-1. One to receive on my end (my uplink) and one to transmit on my end (my downlink), both baofengs.

Then, b/c I don't have a radio that can dual receive that isn't in the repeater assembly, I need one to receive my downlink (using an #RtlSdr), and then a radio to transmit over my up link, my #ft70.

I really need to get a base station.

My at-home repeater project is shaping up to be a monster.

Repeater is three radios. One to rx/tx from my antenna (will likely be tuned to a local repeater), my qrz-1. One to receive on my end (my uplink) and one to transmit on my end (my downlink), both baofengs.

Koukám na #perseidy, ale zatím moc nepadají. Možná mám špatnou anténu nebo jsem na špatném místě oproti Graves.
Každopádně na www.livemeteors.com padají dobře. Tak můžete zkusit poslouchat tam. Hlavní roj má být až zítra.

A growing project. 🙄

My GNSS logger lends a GPS module. Good opportunity to make both Ublox GPS and OpenLog modular, dunking the small diy Li-ion powerbank.

New module: a USB soundcard, intended for in-ear com recording.

The Zero will get a piggy-back module (status LEDs, recording pushbutton, TTL interface for GPS), connected via my non-patented L connector.

Until I find some unused dev time I let @djb's svscan deal with the not-so-daemonish dump1090 service.

Next: IO connector, in order to attach the ublox GPS module and give some status lights.

Great Scott!

The last two days I checked the config over and over again. Got the Raspberry Pi Zero W running as access point with static IP, got dnsmasq serving IPs, but never got SSHd up and running.

Finally I discovered that the dump1090 daemon isn't daemonised at all, blocking all following services. 🤦

I see, in the end I'll be writing a new ADS-B daemon from scratch. 🙄

Well, there are some Python modules at https://mode-s.org by Junzi Sun.

Rig is finally working as headless access point. After years of udev+dhcpcd usage I needed to learn net config again. 🤫

Dump1090 was running, briefly. I suspect the Zero might not deliver enough amps for the RTL-SDR stick. Rig rebooted when plugging it in at runtime. 🤷

Apropos dum1090: the 9999 live ebuild needs a fix. It tries to install files that are no longer in the repo. Will circumvent it with a local portage repo, and push a patch to upstream.

Oooh, SNR ratio seems to be indicating my #auto_rx #radiosonde station is performing pretty well, where it can see this radiosonde. #hamradio #rtlsdr

Ah, caught 3 different radiosondes wandering over the Las Padres National Forest earlier! #radiosondes #hamradio #RTLSDR

I just deployed my personal APRS iGate using a Raspberry Pi and it successfully pushes the beacons of my HT to the internet. 😁
However, I noticed that the RTLSDR dongle is lacking sensitivity.. Is there a configuration I can do to improve that or do I need something like an LNA? 🤔

Here's a #NOAA page about their 17 satellites in operation. #NESDIS is the program.

https://www.nesdis.noaa.gov/current-satellite-missions/currently-flying

and it appears that the #RTLSDR blog has a bunch of current, active coverage of what people are seeing from those birds

I am not sure what hashtags people use so I'm trying a few :)

Ha! First #radiosonde decode and apparently for this one I have the best position... still decoding while this thing is on the ground... (Forest Service Road... Fillmore, California) #hamradio #SDR #rtlsdr #wx

Interesting. I live near a train station and the train seems to interfere when my #rtlsdr receiver.

Ddoe, es i i fryn ger Llangollen. Roedd pethau radio yn digwydd.

Yesterday I went to a hill near Llangollen. Some radio things happened.
I used an SDR to receive signals from a passing weather satellite, and later, decode the signal into an image of the weather conditions overhead.

Any body with any experience with SDRAngel on Linux? I want to decode DMR/DStar/ect but can't find the DSD (Digital Speech Decoder) in any menu. Is there something special I need to do or do I need something specific to do it?
I am using a RTL-SDR v3, and I can get other things to decode like APRS. I just can't figure out how or where the DSD is.

I finally managed to decode a photo from the new Meteor-M N2-3 (Only 10 days old)! While I didn't get too much of an image, I think it was a good second attempt. Decoded with my #RTLSDR and #SatDump
