[amsat-bb] The end of daytime HF?

[skristof at etczone.com]

I've had solar panels with optimizers for 4 months and they definitely
cause RFI on both HF and VHF. I think they are Solar Edge panels. I'll
confirm the manufacturer and, if they are Solar Edge panels, I'll
contact Mr. Simpson. I'll send a follow-up to this forum once I found
out more. 

By the way, I specifically asked the installer about RFI and he told me
that he never heard any complaints about it. Selective listening? 

Of course, I should've done my homework first, but maybe there's a way
to make it work.

If that's not possible, file a complaint with the FCC and be persistent. Mike Gruber of the ARRL can assist: mgruber at arrl.org <mailto:Tom.Simpson at solaredge.com>
