Airspy is currently holding a 15% off summer promotion which runs until June 30. The sale is active at all participating resellers, which includes our own store where we have the YouLoop on sale for US$29.71 including free shipping to most countries in the world. Please note that due to new EU VAT collection laws, EU customers must purchase the discounted YouLoop from our eBay or Aliexpress stores.
The YouLoop is a low cost passive loop antenna for HF and VHF. It is based on the Möbius loop design which results in a high degree of noise cancelling. However the main drawback is that it is a non-resonant design, which means that it works best when used with ultra sensitive receivers like the Airspy HF+ Discovery.
Some good reviews include the YouTube videos done by Frugal Radio where he reviews HF reception and VLF & LF reception with an Airspy HF+, and later tests it with an RTL-SDR Blog V3 using direct sampling. Techminds also has an excellent review on his YouTube channel. We also have a product release overview on this post from March 2020.
We are offering a very generous 15% discount on a selection of #Airspy products for a limited period.

Airspy SDR# Noise Reduction Improvements
We also wanted to highlight some recent improvements to SDR#, the official software for Airspy products, and compatible with the RTL-SDR. One recent development is the introduction of the Natural Intelligence Noise Reduction (NINR) feature which results less audio artifacts, deeper noise cancelling, and lower CPU usage.
