Default New (to me) radio...and NOISE.

I found a very modestly priced Sony 2010 yesterday (FCC
IDAK896AICF-2010) and am pretty happy with it, except for one thing. It
uses THREE size D batteries. Two or four I don't mind, but where do you
find a charger that handles three batteries at a time? It's a pain
having to buy four and then rotate them in sequence. Small problem in
the general scheme of things.

I don't know if there is a serial number hidden somewhere on the thing,
I'd like to find out when in the production run it was made. The sound
is very good for a set this size and the 'sync' actually works, unlike
the 7600 I tried a few years ago. That radio made me buy a Sangean 909.

The noise that's been plaguing me for weeks turns out to be the solar
panel battery charger/regulator. It's worse than any dimmer or
fluorescent light I've ever heard. The unit is an Outback 60 amp mppt. I
don't imagine there's an easy way to stop the noise. Night time
miraculously clears things up.

Clamp on ferrites on all wires in and out of the inverter.

The model 80 on the page are Fair-Rite brand. Loop skinny wires through
twice:

That should do some good; and usually the more
you use the more effective they collectively become.

If you can/have access to both ends of the Wires :
{ Place a Ferrite Bead [FB] on Each End of Each Wire}
Solar Panel [FB] =Wires-to= [FB] Outback
Outback [FB] =Wires-to= [FB] Batteries
Outback [FB] =Wires-to= [FB House

If you have one or more of the Remote Output Monitors
for the Outback : Then Put a Ferrite Bead on each end
of the Data Cable(s) too.

hope this helps ~ RHF

The chokes should go as close to the noise source as possible. They do
zero good at the other end.

Dave -with-all-due-respect-

Unless {Specifically} You Know The RFI Noise Source :
Every Thing Is The Potential [Unknown] Source :
Therefore Treat Every Thing As The Source

Install FBs on Unit "A" -now- Unit "A" with a FB's
on the Wire within an Inch or two from it is Protected.
Those FBs acting as an RFI Shunts for Unit "A".

However [But] the 25 Feet of Wire(s) going from Unit "A"
to Unit "B" are a 'potential' Antenna. This Antenna may
Pick-Up the RFI being Radiated from Unit "A" an inject
the RFI back into Unit "B" and now Unit "B" passes that
Noise around the rest of the System.

Now install FBs on Unit "B" -now- Unit "B" with a FB's
on the Wire within an Inch or two from it is Protected.
Those FBs acting as an RFI Shunts for Unit "B".

Oops there is also a 25 Feet of Wire(s) going from Unit
"B" to Unit "C" are a 'potential' Antenna.

the process of elimination continues ~ RHF

I have small slide-on FB's on all the Wires on the Solar
Array of now 88 Panels : The Contractors said it was not
necessary & I Said Do It.

I have Clamp-On FBs at the Service Feed Box at the
base of the Solar Array.

I have Clamp-On FBs at the Service Entry Box at the
Controller / Regulators / Inverters.

I have Clamp-On FBs at the Enclosure for the Batteries
about 3-Inches from each Battery.

Except for the 200KW Generator at the Corner of the Pond
going 'On' and the snap-crackle-pop of a string of Power Grid
Towers about a 1/4 Mile Away {Lions Dam to the Valley}
I get an S-Meter "0" on many bands between RF Signals.
and I Run 100 Foot+ SWL Antennas.

I Am One Old Believer In "FB"s Everywhere : Especially
When Wire Runs Get Longer than 6~8 Feet- iane ~ RHF

Who's generator is it ? A local hospital/hotel/FD ? Sounds a little
heavy for a household back-up thingy !

Mike [M II] only presented a Half-Truth from this Post :

"My One Big Problem During a 'Local' Power Outage is
that the Local Water Company has a Kohler 200 KW
Back-Up Electrical Generator at the Corner of the Pond
with in 100 Yards of the House."
http://groups.google.com/group/rec.r...bcf0bc4ff6eac2

It's the Water Company's Generator and it within
100 Yards of the House.

yes - it is that simple ~ RHF
