[TenTec] which power supply…station efficiency

[resluder at yahoo.com]

If you are a member of the ARRL, there was a shootout of sorts on switching supplies just a few months ago.  All will have a little noise, but a lot of the models in the article had a pot to adjust/move the noise if it interfered with one of the radios you are using.

I use Ten-Tecs switcher supplies, but they are usually an OEM device with their name on them.  Astron and Chinese manufacturers.  None that I own have the ability to move the noise a we bit.  However, they work fine for me.
