I tracked down some RFI problems on the 2M band to several small
Interruptible Power Supplies in my house. These are the half-a-shoe-box
size units intended for use with PCs. I assume the switching regulator
inside is the source of the noise.
I am thinking my best strategy is to replace them with higher quality
units (rather than try to suppress the noise).
Any suggestions on models of UPSs that don't radiate?
Any other ideas?
