Any idea what this might be?

This is advertised on Lazada which is sort of like ebay.

Miracle Shining 10X(RTL-SDR Blog V3 RTL2832U 1PPM TCXO HF BiasT SMA Software Defined Radio

The description translated by Google says

• Designed specifically for pre-sensitive sensitive protection end from high levels of RF effect from nearby signal transmitting;
• The SDR receiving Antenna is very close to antenna transmission, or supporting antenna or Failure systems that cause a high RF water input receiving antenna input, may cause SDR receiver to freeze.
• Measurable: receive antenna is 10 meters from antenna transmission, and transmit function is 1000W. The SDR receiver can work normally.

• Only receive protected front head, 50 or 75 Ohm compatible; preamplifiers and radio protection from excessive RF.
• Has all the great features, and shares an identical Form factor to ensure compatibility with the surrounding options.

I have no idea and don’t want to spend ₫447,000 to find out.


Sounds like either a RF filter (but for which frequencies) or maybe some static electricity protection?

Maybe it’s just the rtl-sdr v3 receiver? And the picture is wrong? :slight_smile:

The possibilities seem endless!

IMO it’s just the protection “front end”.
