I've been wondering where the Corsair and Corsair II fall (@ 2Khz) in that table. It's also a bit curious that the Atlas 350-XL and KW TS-820 weren't included in the list below, they have very good D

Mike is correct, the Ten Etc ~18-22 amp linear power supply models that have the 2 pass transistors do have the over-voltage crowbar protection built into them from the factory. These are the 255, 26

Yes there are a number of differences beyond paint. One of the major functonal differences is that the CII has an audio filter that helps with CW ops and a built electronic keyer. Under the covers th

At least from a high level, based on various comments here I do get the sense that quite a few don't really grasp what the basic CPU/DSP architectural design of the Orion is (or any other modern DSP
