The FLEX radios (and all digital radios following this architecture) are
indeed, nothing more then confuser peripherals. So, how do we find out how the
current, supported DSP software works its magic with the digitized low IF that

Yes, welcome. Except, if you try AM on the West Coast AMI net, even

Well, it depends. If the spur is just 2.4 kHz from the carrier, and
depending on its energy level relative to the unmodulated carrier
level, and whether or not it is a discrete tone, or gets modulated as
the main signal does, e.g., SSB mode, it might possibly slip through
regulatory cracks
One easy to create a cool echo (experience from my first day with
F5KA) is to forget that you have the monitor turned on in SSB mode.
I'm sure there are other ways.
