I've heard some say that this isn't true, that brand X 6m RX didn't workt with brand Y 6m TX, but details were never really given. That was useful, but I forgot to ask: Is the space (no pulse) frequency the nominal frequency, or is it (more sensibly IMHO) 1/2 the shift below -- or at least _some_ amount below the nominal? If I were designing such a rig I would have the space frequency (off, no pulse, whatever) be 1/2 of the shift _below_ the nominal frequency, and the mark frequency be 1/2 of the shift _above_. I may shade the space frequency to be a bit closer to the nominal frequency to balance out the spectrum, but I doubt that I'd stick it right onto the nominal frequency.
