@swradiogram.bsky.social Final three images received in northern Florida, USA. A great group of vibrantly colored images tonight! Received using Airspy HF+ with MLA-30+ active loop antenna. FLDigi and SDR# beta of v.1922-64bit.

🎙️ One-two, one-two, is this thing on? It’s been a minute! Late to the party but here’s uConsole CM4 running CubicSDR with #AirSpy HF+ Discovery.

@swradiogram.bsky.social Sunday/Monday overnight. WRMI on 5850 kHz continues to hold up very well into northern Florida, USA. Unattended reception using Airspy HF+, SDR#, FLDigi and W6LVP active loop antenna.

@swradiogram.bsky.social Final group. Received using Airspy HF+ and long random wire antenna. Kim, hope you get you power restored today!

Many thanks to @airspy.com for the wonderful service! I'm now back listening to the HF bands with a shiny new Airspy HF+ Discovery!

How good is #Airspy's DSP? youtu.be/bt6voi8W8DQ

In other news, I managed to reach a sustained throughput of 2680 MSPS (Single ADC) and 1150 MSPS (Dual ADC) with the full DDC implemented in software using one thread of my Ryzen 5900HX laptop. 3.5x the speed of the state-of-the-art. Any idea what can this be used for? #Airspy

I found some pulsed noise this morning and I thought this would be a good demo of SDR#'s Wide Band Noise Blanker (WB NB) and Natural Intelligence Noise Reduction (NINR.) Here's a quick video of the different combinations. Used an Airspy HF+ and a YouTwin Loop. www.youtube.com/watch?v=5HdU...

After many optimizations, the performance is nothing short of spectacular. Not bad for a simple piece of speaker wire and a ferrite core.

We are in the planning phase of a new permanent multiband WSPR receiver on Marion Island - Callsign ZS8A using an Airspy HF+ Discovery - scheduled deployment in April 2025 -Thanks to the South African National Space Agency #hamradio #spaceweather #HFPropagation

The Airspy receiver and an ALA-1530-LNP will be installed at the Marion Island Research Station, a particularly quiet RX site. #hamradio #HFPropagation

The #YouTwin, ladies and gentlemen.

@swradiogram.bsky.social A good representational mix of images decoded this morning in northern Florida, USA from the 1330-1400 UTC broadcast on 15770 kHz. Mixture of backscatter and multipath signals here today. Used Airspy SDR#'s Mult-Notch IF filtering to help suppress LSB RTTY.

Choice of x86 and x64 versions, and beta versions too! If you rely on specific plug-ins, be sure to keep a working copy and install test software to a fresh directory (and not in Program Files!).

@swradiogram.bsky.social The old clock on the wall says it's time to wrap things up. OK, last image! Spent most of the day setting up Windows 11 on some repurposed and new hardware. Decoded with Airspy HF+ hardware, SDR#-rc, and FLDigi software.

It turns out Bluesky is the same shit as X/Twitter, but in the opposite side of the political spectrum.

Best of this morning's ISS SSTV pictures, using a Airspy HF+ Discovery and the infamous 2m loop propped up on a chair in the garden 😁

Massacre... 😩

We had another visit by SA Power Networks to AREG's remote site today, to install fixes for our power-line noise issue. Technicians inserted wire brushes into the insulator joints, which had an instant effect on the noise! Thanks SAPN! www.youtube.com/watch?v=-5R_...

7330 kHz: Radio Joystick, Charlie Prince Show, has just came up via Moosbrunn🇦🇹! No doubt it's the Moosbrunn tribute programme that was supposed to run last week, but they repeated the usual 1st-Sun-of-the-month show instead. #shortwave

Trying to understand why #WEFAX images with my RSP1a are much worse than with my AirSpy HF+ Discovery. Examples below. 2 similar PCs side by side, 2 MLA30+ loops, same version of FLDigi. RSP1a is always much worse. Same results if I swap the antenna. Pt Reyes 17149.3 khz USB at 1923 UT today. Ideas?

#Airspy HF+ Discovery vs #SDRPlay #RSPdx 40m band #WSPR decoding performance full article at groups.io/g/wsprbeacon... - This is the conclusion of 4 weeks of tinkering and comparing SDRs, now back to DX hunting... finally #hamradio

Worth noting that the #Airspy HF+ Discovery and the #SDRPlay #RSPdx are excellent #SDR in my RX performance comparison on the HF bands. The final 40m comparison is ongoing and I expect the results tomorrow - mind you, a 14-bit ADC doesn't have to hide behind a 16-bit ADC #hamradio #swl

I picked up quite a few #SSTV images from Mexico yesterday on 27700 USB, the popular freeband 11 meter SSTV frequency. Received here in Westminster MD USA on an Airspy HF+ Discovery SDR, dipole antenna, and decoded with my Black Cat SSTV program. www.blackcatsystems.com/software/sst...

Yet another AD9360 based #SDR got announced for crowdfunding today.... How many is too many, its all the f*cking same, all the same bullshit just with different APIs!?!!

#Airspy vs #RSPdx draw on the 20m band #WSPR decoding performance #hamradio #SDR

always great when the documentation starts with whose national style the manual will be written in (SDR# Big Book 2024, English version, Paolo Romani)

Had a great time capturing the 31 meter band for 3 hours this afternoon using my Pi Zero 2W portable recording contraption and @airspy.com HF+ Discovery with the new firmware. Flawless baseband AGC despite a very hot antenna (2x6m dipole) AND the HF preamp being on. #PortableSDR #SDR #Shortwave 📡

There's quite a bit of 11 meter freeband (unlicensed CB) #SSTV activity on 27700 USB this morning. Received with an #Airspy HF+ Discovery, 11m dipole antenna, and decoded with my Black Cat SSTV app (for Windows and macOS) www.blackcatsystems.com/software/sst...

It is noticeable that the #Airspy has created more unique spots than the #RSPdx on 15m #hamradio

AirSpy R2 + SDR# Studio v1.0.0.1920 (SDRSharp) beaucoup plus ''sensible" sur signaux faibles qu'avec SDRPP 1.2.1, constat fait sur portion CW/SSB bande des 2m sur les balises... Why ?
