Good point here... I have heard similar comments from local ham radio operators, who run also BO equipment. Althoug SMPS would not be main topic of this thread - it needs to be considered as potential interference source.
I have also planned to modify HP server 12V power supply for amateur radio use, and it also used SMPS principle
. If there is interference, remains to be confirmed...
