[IRCA] The Bad News

[Stan Horzepa <stanzepa@xxxxxxxxxxxxx>]

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?
