Just a note that our RTL-SDR Blog V3 units and antennas are now back in stock at Amazon.com with local US stock. There were a few manufacturing and shipping delays related to COVID-19 so they had been out of stock for a couple of months. Currently they are being fulfilled via our partners based in Chicago, and all orders will ship out within 2-business days via USPS First Class. We will look at replenishing the the Amazon Prime warehouses in a few weeks and at the moment we are only shipping to US customers from Amazon. US customers can also order directly from our store at www.rtl-sdr.com/store and this will result in the shipping fee being waived.
If you are based elsewhere in the world, please order directly from our store at www.rtl-sdr.com/store which ships non-US orders direct from our warehouse in China. Alternatively some countries might benefit from our Aliexpress store, which can now utilize the reliable Aliexpress Standard Shipping line.
Our RTL-SDR Blog V3 is an improved RTL-SDR dongle. It includes features like a TCXO, SMA port, software switchable bias tee, built in HF direct sampling mod, aluminum enclosure, improved ESD protection, improved cooling via thermal pad and many other design improvements. The kit comes with a multipurpose dipole antenna which is extremely versatile. It can be used as a standard vertical dipole for terrestrial signals, or can be mounted horizontally in a V-Dipole configuration for NOAA/Meteor LEO weather satellites. It's also easy to mount outdoors through a window for best reception with two mounting solutions included.
