My Mobile Station is : IC706mk2g, Acer laptop
Problem: when I plug power to laptop I get S9 to +20 hash noise either moving or sitting still motor off.
This tells me the noise comes from laptop power source.
I have tried the power supply that came with laptop thru an inverter and using a universal car adapter....same thing. The vehicle is company so I cannot mod it BUT is there a way to cut the noise from the laptop power source?
By the way with laptop off I have may 1 s unit noise on 706.
Tnx for any help, I want to do PSK31 mobile(sitting still of course)
