Introduction

September 28, 2017 Airspy has announced the HF+ as 'a paradigm shift in high performance HF radio design' and this is very true. The HF+ has a target price under $200. Here are some screenshots comparing the HF+ with the NetSDR which is arguably the best HF SDR available today and is the SDR of choice here in the SDR-Radio.com office.

The tests were made using a Wellbrook loop antenna, model ALA1530LNP. the antenna was connected directly to the receivers for tests on VLF and NDB, for higher frequencies a Stridsberg MCA104M antenna multicoupler was used.

Compare the screenshots and decide for yourself just how good the HF+ is.

Note: VHF screenshots for the HF+ will be added later.
