I was wondering about the noise from my Samlex SEC-1235, and so I did
a survey of the noise it puts out, using my RFSpace SDR-IQ receiver as 
a spectrum analyzer, 150 KHz at a time. 

Turns out the Samlex supply puts out some noise down in the 50 KHz to
150 KHz area, but not a lot, and it's essentially noiseless elsewhere. 
This comes as no surprise: the manual said that it was designed with a 
mind to keep the QRM down. 

Congrats to the XYL!
