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?
