I'm not sure that the power supplies were manufactured by a third party; I've had a couple of these apart and I didn't see anything that would leave me to believe that... But the important thing is t

7. [Amps] SPE 2K RTTY Duty Cycle / spectral cleanliness (score: 1)
Date: Fri, 22 May 2015 13:30:56 +0000 (UTC)
Spectral purity is even more important in amateur radio, as individual stations do not have fixed frequency assignments ('channels') and no analysis of the consequences of interference occurs prior t
