Ferrite may or may not help. Wall warts and tablet supplies can be notoriously noisy as they get older.

Have you put ferrite rings/toroids on your power cord and all USB cables?

I use a SideKar logger and small Bluetooth keyboard, no computer needed when portable.. Made for the kx3 but I think it is now or will have capabilities with other radios.

Here is a good challenge.  During Field Day I was using my HP laptop on batteries.  When it started showing a low battery I plugged it in to charge.  That is when a good amount of RF noise started to the point that I could no longer hear some of the stations.  Any ideas on how I could remove or at least lessen this noise issue?  Now realize the HP power supply was plugged into an BlueTTI power station since I did not have power available.
