I had a similar problem with a very strong noise that increased in frequency. I wondered for weeks where it was coming from and low-and-behold - it was the Astron SS-30 sitting on top of my ham gear. I was using it for the 2 meter rig and other smaller stuff. I replaced it with a linear model and all is well.
My point is, if you think you can solve this problem by buying a different brand switching power supply, you may be disappointed.
