I’m curious how the RSPdx compares with the Airspy HF Discovery (which is much better on LW than the original, unmodded HF+).
I have an Airspy HF+ (bought in early 2018) that I’ve used a fair amount, and a Discovery that I’m just beginning to use. So far, their performance on LF/MF seems similar. I’ve heard others describe the Discovery as offering similar performance to the HF+, but in a smaller package at a lower price.
Is there anything out there worth reading that discusses (and hopefully quantifies) ways in which the Discovery shows better performance?
