I may have found the source of the powerful clicks on the airwaves. It's likely China's over-the-horizon radar (OTHR), due to the ongoing military exercises near Taiwan. bbc.com/news/articles/c87l7x…

A powerful clicker has appeared on shortwave. It is most often observed in the direction of Asia. I listened on several WebSDRs. You can observe short powerful clicks around 21 MHz. It might be some kind of over-the-horizon radar.

The AD9371 chip has been around for a long time, but it never gained the same mass popularity for building TX/RX SDRs as the AD936x. On top of that, the evaluation board used to be prohibitively expensive. Now for $275 and have live 100 MHz bandwidth goo.su/zwJcTp1

I think that a circuit based on the AD8367 could be used for a broadband mini-loop amplifier also. aliexpress.com/item/33026929…

I use this inexpensive board with a differential amplifier for a loop antenna. It performs very well at frequencies from 4 to 28 MHz. And can compete with LZ1AQ and Wellbrook designs. aliexpress.com/item/10050080…

Owners of KC901 devices can use the KCSDI software. Carefully read the firmware update instructions, or you might turn the device into a small brick. But it’s not a big deal. My first attempt at updating also failed. I had to remove the batteries.

I've noticed pirate activity on the Meridians lately. Can listen to the frequencies 484.267–484.268. It's preferable to use a Yagi antenna with at least 3 elements.

If you use this RTL, keep in mind that sensitivity drops in the lower part of the range, and the reference oscillator frequency may become unstable. Therefore, reliable reception starts at 22 MHz.

I bought this dongle to add to my collection, and it be interesting. Nice cast and heavy metal casing. Sensitivity is worse than the V3. It’s detected as an FC0013 chip. I haven’t looked under the cover, but I think it’s a variant with an L-band input. RX (tested) 21.1–1897MHz.

Try listening to 460.635 MHz. Might be able to pick up voice signals from a reusable space capsule. n2yo.com/satellites/?c=2&p=A

I'm not entirely sure, this recorded recently on August 1, 2025, at a frequency of 460.636 MHz, likely contains operational communications from the SpaceX Crew-11 spacecraft during its launch. The signal exhibits a characteristic Doppler effect. drive.google.com/drive/folde…

The other day, the author of PhantomSDR released the second version. And it looks amazing! It doesn’t have (sorry) the silly limitations of Twente's WebSDR. It’s faster than the clunky OpenWebRX written in Python. I looked at the program’s code. It’s simple and elegant.

The excellent sysmocom's L-Band cavity filter 1525-1705 MHz is back on sale. This is not an advertisement. The filter is truly one of the best you can buy. Insertion Loss <= 1dB. shop.sysmocom.de/L-Band-cavi…
