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?

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.

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

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!).

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.

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!

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

#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
