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...

Thinking of putting up my Twitter archive online somewhere, now that I've officially closed that account. Unfortunately the archive is missing replies from other users and all the other interactions but it's a vault with many good memories of doing radio in the field.

Happy New Year! A Fresh Start and Update on 2024 Correspondence

Good Morning! It's January 1st, 2025, and I'd like to wish you a very Happy New Year! I mentioned on Patreon yesterday that, in a sense, I’m happy to see 2024 in the rear-view mirror. Frankly, it was a tough year for our family in many ways, but even amidst the challenges, there were moments of celebration and joy.

Saltwater Activation: Always Wanted to Try This…

I finally got to try something I’ve always dreamed of: proper QRP saltwater ground-planing! This week, we’ve been in Beaufort, North Carolina—a charming coastal town that I can’t recommend enough. As I mentioned in a post last week, I brought along my Elecraft KX2 and KH1 for the trip. On Tuesday, we hopped on a small boat/ferry to Cape Lookout National Seashore (US-0683).

For the US friends. While the BBC does not target North America on shortwave, it is not ruled out you might get overspill reception from a transmitter for somewhere else: www.bbc.co.uk/programmes/a... I for example receive NHK in Japanese although no shortwave transmitter explicitly targets Europe

I really just get my Airspy HF+ updated to the latest firmware. I’m too many versions behind and there are too many improvements not to do this now!

London Shortwave @londonshortwave.bsky.social · 12/12/2024

The PiZero 2W spectrum recorder runs for 7 hours on two 18650s & a step-down 5V converter (which doesn’t seem to add measurable noise on HF). And of course the batteries are hot-swappable as the unit has its own small UPS battery. The only limitation is the amount of free space on the MicroSD card 📡

1/2 After a few charge and discharge cycles, the 4xAA Eneloops support the built-in battery for longer: the recorder kept going for 4 hours and 10 minutes. That's long enough for most of my park outings! Here's the resulting capture from last night. The system is good to go! 🚀

Final version of the UI (for now). Battery indicator, remaining recording time available & the duration of the current recording (in hh:mm). The Pi boots into this UI and triggers airspyhf_rx to record with the selected parameters if a HF+ is connected. The screen has minimal 🔋 impact when sleeping.

1102

London Shortwave @londonshortwave.bsky.social · 30/11/2024

Experimenting with a new physical interface for the spectrum recorder. Added an option to switch off the backlight to save battery (& when I send the UI to “sleep” this way, I also change the controller polling interval from 0.1s to 1s to reduce Python’s CPU usage). These things matter on Pi Zero 2W

1/4 This is my most portable shortwave spectrum capture contraption yet. A Pi Zero 2W rigged up to an AirSpy HF+ SDR. The Pi has a Waveshare UPS HAT with a small capacity LiPo battery — enough for 70 mins of recording. It is further supported by 4 AA Eneloops, adding 100 mins of extra recording time

🇩🇿 I love the fact that Radio Algérie Internationale is broadcasting 24/7 on 531 kHz. It can be heard in London clearly at night, even indoors with a passive loop antenna such as Tecsun AN-200, and so provides for some accessible home-based DXing.

As recommended by Paul PD0SWL on Twitter/X, I looked for a small tuned MW loop at home and found my Tecsun AN-200 that has a wired connection port. Excellent results: easy to de-emphasise intermod source so it disappears and reception much better than w/ whip. (Video: mastodon.radio/@LondonShort...)

London Shortwave @londonshortwave.bsky.social · 28/12/2023

3rd gen Belka is a little hot on the whip on MW. There’s intermod from a strong nearby station on 558 kHz (Panjab Radio) that can be eliminated with the help of a simple attenuator. Surprisingly, the built-in “sensitivity” setting doesn’t address this problem (video: mastodon.radio/@LondonShort...)

000

London Shortwave @londonshortwave.bsky.social · 11/12/2023

The 3rd generation Belka is a nice little radio. Testing in a London park, I did notice some overloading / images on medium wave (not shown here). Not sure if the source of those are strong VHF, shortwave or medium wave signals. Will do some tests with preselectors to find out.
