tonight. Listed as 6.25 kW and totally dominating the channel. Normally I
have terrible splatter from Blaine on 1600, but tonight my North directed
corner fed loop is performing admirably. My other antennas are favouring

A fair carrier on 1566 this evening. Also weaker ones on

You are, of course, correct Chuck. I'm impressed that your link shows that
some companies actually care about RFI. Nice to see, for sure! One day,
it'll come to Masset! 73,...Walt

The electronics is a small part of the tens of thousands and it causes the
interference, not the actual solar array.
As mentioned, some manufacturers are well aware of the problem and claim to be
successful at reducing / eliminating it.
Noted, Chuck. You can imagine, though, if after 10s of thousands of $
spent, only to find an increase in noise as a result. At best, there'd be
no worsening of noise. Still, 50/50 isn't good enough at my end,but I'm
glad to hear there is hope for low/no noise sources! I'd like to think of

I'd check around before writing off solar array chargers. They're just like any
other switching power supply that takes in voltage A and converts it to voltage
B.
And just like 12 VDC to 110AC inverters, some are noisy and some are quiet. It
is popssible to find inverters that are
Thanks for that information, Don. So there are solar arrays that can be
quiet. My concern would be that if I installed such beasts at my
locations, it'd be done commercially, and I wouldn't know whether there'd
be any RFI until after the fact. I'm sure the contractor would have no
idea, nor

I have about 7 kw of solar installed here Walt, with almost no interference
issues. But no charge controllers are used and the inverters are actually
APC brand UPS's.
And I also have some Dlink PowerLine extenders (DHP-306av) in use, one
circuit passes within a few feet of the Wellbrook loop and
Colin, I've thought about solar arrays, too, both in Victoria and in
Masset, but the RFI risks are simply too great, especially for Masset. The
power has to be stored somewhere, and it's the inverters that scares the
bejesus out of me. Otherwise, I'd embrace them immediately!
Unfortunately,
Thats a real smart idea.. NOT

Build the antennas so big they're physically threatening to the neighbors.
Show them the rip-cord you can pull to 'accidentally' topple them into their
yard.

On a QRM side bar, tracked down a huge source of daytime RFI to a neighbors
solar array inverter that blasts the MW and HF spectrum with a buzz every 100
kHz or so.
We are very good neighbors and he was quite upset to

A fair number of carriers today, with seemingly a mix of Asians and
DU, though most were pretty weak. Audio was rather limited:
1116 4BC Brisbane, AUSTRALIA Traces of song by Lionel Richie at 1435.
Confirmed on webstream..
1575VOA ThailandVery weak, with bits of talk
Other than traces of a signal on 1566 kHz around sunrise (1333 GMT), it has
been a rather quiet morning here.
