I've always wondered what an SDR like the @airspy.com could hear while connected to an antenna atop a high tower. Roman Porterfield put together an awesome video near Jamestown, N.D. that answered my question! At just 22, he's also written some awesome software that aids his engineering duties!

@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.

@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.

The throughput on an Intel i5 13gen with one thread, decimation = 512, using 32bit floats: o Real Input (one ADC) / Complex output => 3840 MSPS o Complex Input (Quadrature sampling) / Complex output => 1852 MSPS

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

This morning's beta also improves the performance.

-140 dBFS is enough? Check the Beta.

You didn't notice. It means it's so good.

Maybe. Or maybe use our own compression that's used in the SpyServer.

It's a 1:1 TLT. Try mix 43.

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...

10 ~ 15m of speaker wire as a triangle pointing up. The BALUN is in the middle of the bottom segment. Use a TLT type transformer like the photo.

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

Could probably work for 6m with some modifications.

@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!).
