An ATS-25 receiver has appeared on eBay and similar sites. It appears to be a touchscreen and user interface update to the previous ATS-20 model. I suppose it remains to be seen if there are any improvements to the underlying electronic design and construction quality.

At $130+ I am not sure if I am inclined to find out, but perhaps someone out there might be interested. Given the design shortcuts and potential build quality concerns of the current ATS-20, I would suggest considering the ATS-25 a possible “kit radio” as well until if or when proven otherwise.
Best Regards,

Thank you for the tip, Robert!
I would certainly welcome a guest review of the new ATS-25. If you’ve purchased this radio and would enjoy reviewing it here on the SWLing Post, please contact me!

Hi Tom,
Ricardo (PC2CLR) recently published an excellent firmware update for the SI473x kit-based receivers flooding AliExpress, eBay, etc.
I purchased a preassembled SI473x model, and it has a much better user interface following the update IMO. Other changes include being able to tweak or disable soft mute, finer grained attenuation, and a few options being moved to the encoder instead of multiple button presses.
The update including directions and a list of features can be found here:

Robert also kindly shared the following internal photos of the SI473x receiver:
Robert, thank you so much for sharing the information and your SI473x photos/mods!

You probably have seen the info months ago, but I just noted Tecsun China has officially launched the Tecsun H-501 receiver in China priced at 1500 Yuan, which is about $230 USD. Add shipping.
The Chinese domestic market H-501 model on AliExpress and Bangood has been averaging $400+ USD. I have no idea if the Desheng/Tecsun store ships outside China, but it seems like a considerable savings for customers outside of China if actually capable of ordering there.
The Tecsun homage currently features a H-501 banner:
The homepage link for more info takes you to a Desheng/Tecsun sales page including specs, multiple pics, consumer reviews, etc. here:

Thank you for the tip, Robert! I’ll be waiting for Anon-Co to distribute the export version of the H-501, but the 1500 Yuan/$230 USD price point is much closer to what I expected rather than those early inflated AliExpress prices. Thanks again!

I recently received the new Tecsun AN-48X loop antenna. I have not had much time to thoroughly test it, but I can make one immediate recommendation IMO. Replace the bundled “feedline” between the loop and controller with an actual *shielded* 1/8″ male-to-male stereo audio cable.
The bundled cable causes near-hand capacitance at the controller, potential RFI issues, etc.; at least for my received unit. The noted concerns largely corrected when replacing the bundled cable with a 6′ shielded audio cable. Tuning now works as expected, and SNR seems much improved.
I have longer 12′ shielded cables and some 1/8″ female-to-female couplers on order to eventually try longer feedlines should the need arise. I will try to drop you a line if/when I get around to testing them.
That’s a sound suggestion, Robert! Thanks for sharing!
Many thanks to SWLing Post contributor, Robert Richmond, who shares two images of the Tecsun H-501 dated June 21, 2019 from this radio forum.
As Robert notes, “Probably a prototype, so YMMV.” Very true–it’s quite possible further changes could be made to the design or silkscreening before a full production run.
The photo above with BG71CA does give us an indication of the radio’s overall size.
Thanks for sharing, Robert!
