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.

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.

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?

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

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

Introduction
[image of italian tricolor with ITALIAN STYLE printed above/below]
Much of my energies and passions for SDR could not be dissipated, but rather gathered
and reasoned out since the energy released from each and every word has the power
to redraw the map of everything we know and it is unspeakable fun for me to unravel
these threads and wind them onto the spindle. In fact, this book was born from here: this book was
born here: from the giddiness of exploring and disseminating the power of SDRSharp because today,
more than ever, our world is SDR (Software-Defined Radio). Since a work like this did not exist, I
decided to write myself a small guide in the beginning and a big book now. A rich word map for all
SWL friends, radioamateurs, specialists or just curious.ITALIAN
