Stan,
Although I don't use an Elad, I've had similar problems with my MacBook Pro
and I haven't figured out a good solution either. I generally don't DX
live long enough for the battery to run out. When I do an unattended
recording, I turn off demodulation, turn off the FFT/waterfall, and turn
off the screen. I can get about 7 hours that way.

I bought an ELAD FDM-S2 SDR receiver and I am using it with my MacBook Pro
under Windows 10 and Parallels.
I am very happy with my new radio, but there is a problem: interference
from the MacBook Pro battery charger/power supply. The interference is so
strong that only the strongest AM stations are above the noise.
The cable between the charger and the computer is the problem because the
noise disappears completely when I disconnect the cable from the computer
even though the charger is still powered.
I installed ferrite cable clips on the cable, but that made no difference.
I wrapped the cable 20 times around a toroid ferrite core, but that made
no difference.
One solution that works is to use the ELAD-MacBook Pro combo without the
battery charger. This gives me a few hours operating without the
interference, but sooner or later, the battery will need to be recharged.
Anyone have any other solutions?
