Hey, the "solution" to equalize peak-to-average is to use CW, PSK31, RTTY, or if you must, digital voice! I suppose you could also use NBFM if you want to keep your linear busy. Seriously, the Orion

Yes for some radios, but not the Orion. The Orion "dial" frequency is the center of the passband for LCW or UCW if PBT=0. An incoming signal at that freq. produces a tone at the sidetone/spot freq.,

Agreed these are good articles. But they are "concepts", and they may or may not tell us what is inside the actual v1 Orion as delivered, let alone v2. In my view, TT would do well to explain the DSP

Interesting question. Maybe 60 Hz hum rejection? I've never really understood the philosophy of "TX EQ" vs "SSB L.F. ROLLOFF". I would normally set the LF Rolloff to >= 150 Hz to reject hum, and TX E

Depends on the application. You could use aluminum (or copper) foil for a great low impedance ground, but it wouldn't work very well for lightning protection! I think this is off topic for the TenTec

Ferrites can help, but if you really want a "good" RF ground, it should be less than about 1/10 wavelength long at the shortest wavelength you want to use. So about 3 feet in the 10 meter band! If it

The question is whether your "ground" wire carries an appreciable RF current. If it does, and if its length is a significant part of a wavelength, it will radiate. There's no avoiding it. Your "zero
