Topband: Power Supplies and Top Band noise man made noise

[Michael W Elliott]

Pulse noise and rfi with switching supply on 160m

I thought about not writing this but then decided it might help someone else who was having same problem as me

I was using an Aston SS-30M  power supply for my Orion II for power.

Although this is a good power supply and I thought adequate for the Orion II, I had some unusual noise on specific frequencies that really hampered marginal signals.

Like  between 1810-1819 and other areas.  You know those DX areas where the dx like to transmit.

After swapping it out with an Astron RS-35m things are a heck of a lot quieter and the rig is functioning great.

The techies  can dissect what may have been the problem but I found a simple solution for my situation.
