Yep I do run HF and also I have recently used these devices (and so has next door as I was asked to install them for him) I got a few squawks on a few bands but rerouting the co-ax/proper earthing and a low pass filter soon dropped them to a minimum that was below the snr thresholds apart from on a few spot frequencies (had far worse interference from other hams)
What I do get sick and tired of is other hams who have had bad experiences with a few cheaply made homeplug copies who think that there should be a blanket ban on all other technology just because they have a radio licence by answering a load of multiple choice questions and then seem to spam all the radio ham forums to that extent..
Reminds me of the days when hams where up in arms about RTTY, then AMTOR, then Packet and most recently APRS
