Airspy have released their black Friday 2020 deals today with 30% off. Back in 2019 we saw that the black friday deals were the best time to purchase an Airspy and we don't expect pricing to get cheaper than this. Links to their distributors can be found on airspy.com.
Airspy sell a range of software defined radios. The HF+ Discovery is one of the best (if not the best) low cost HF SDRs we've ever tested, and the Airspy Mini and R2 are good wide band VHF/UHF radios that are a step up from RTL-SDRs. The SpyVerter is a good upconverter that is also compatible with RTL-SDRs, and can be used with the bias tee on the RTL-SDR Blog V3.
The sale brings the pricing down to the following prices in USD (plus shipping costs):
