HB3XVQ and I tested last week the new Fobos SDR from RigExpert, we did not got it working well and had allways issues with mirror and ghost signals.
After having seen this review here today, we will return the FobosSDR and would not recomend anyone using it for a PhantomSDR+
Yes, for hf the best you can get probably is the rx888 mkii.
Since 2024, Fobos receive two firmware updates.
Now, it work drasticaly better.
I use one with sdr++ on Linux or W11.
Work well on HF but this RX is clearly made for VHF/UHF, overcoming other products i had tested.
At this time, i'm newbie with Phantom but i hope be able in the future to use a Fobos.
I'm curious ! :(
