FR24 box with 3x usb rtl interference

[Mini]

Hi all

I'm a FR24 seeder F-EGXH1
My problem i have after testing all eqpt fr24 box is causing a harmonic or 30 over most of the vhf air band when using 1, 2 or 3 usb rtl sticks its so intrusive that spoils the 3 radios i run
is there away of stopping the leak from fr24box ?
fr24box is in loft and usb units are below in a room as far as i can apart but no joy

when fr24 box is disconnected awsome silence but i cannot do this i need it on 24/7

if any one has any ideas i could try to screen either fr24box or usb sticks to stop it



thanks

Interferece could be from FR24 box adapter.
I think someone here did mention that but not sure.

What kind of anntena are you using for sticks? Original one?
