    Vic - Yeah, had asked on QRZ a year or so ago and didn't get much satisfaction.  Now that running the AC line to the breaker panel in conduit has significantly diminished maybe I don't have to be so picky.  Next time I have the breaker panel cover off I'll see if I have a mix 31 to replace the mix 43 with.

    Guess I bragged too soon.  Yesterday I fired up the radio and my inverter hash was back.  the only thing different is that we got 6" - 8" of rain over about 4 days so the ground is 1oo% saturated. I have at least been able to get on 20M and work the West Coast the past couple of days...  I wish I had an O-Scope up here...

    I removed the three turn mix 43 choke and spliced in 12 turn mix 31 choke.  Don't see a whole lot of difference...

    Hi Justin,  Thanks for the pic.

    If it is easy,  please try removing about half of the turns on that toroid,   and note any difference.   That is a very large core,   and is quite useful,  when dealing with large gauge cable.

    As boB,   and others have noted,   it is quite possible to have so many turns on a core,   that there is coupling twix the windings,   which can create more RFI,  compared to fewer turns on that core.   Also,  it is often a good idea,  to try to space the turns around the core,  such as to try to minimize this coupling.

    IMO,   73,   Good Luck,    Vic

    Not that big, really, ft240-31 with 12ga solid...  Will make another and save this one for a balun...

    Radio is running off DC, straight off the battery bank.
