[Elecraft] FLDIGI and K3

[Bob Darlington]

Yes, that was it.  I just tested it and sure enough it's the power supply.
I had the idea that it might be the supply only being noisy under load and
that was it.  Confirmed.  The Pi makes the S meter move too, but not
anywhere near what this thing is doing.  Time to get a new supply I guess.

Sorry for reducing the SNR.
