[TenTec] 252mo supply

[Chris Howard w0ep]

Thank you Ralph!

I hooked the Omni up to a Pyramid linear supply
that I have here.  I can run up to about 10 watts
and then the voltage sags enough to cause the frequency
to change.  So, I am ok if I stick to lower power.

I'm going to dive into the 252mo supply and see
what is what.

Do you think it would be better to get a switching-type
supply?  Should I be worried about noise on the power
line?

Chris
