be persuaded to get the required frequency accuracy/stability and to beacon
mostly a carrier with the minimum required CW ident. and be listened to by
US/Canada operators using the narrowest DSP bandwidth on receivers with the
required accuracy/stability possible, then this has the best chance of
succeeding. Success in this mode would provide a benchmark for other
modes.
Another trick is after 5 minutes or some other convenient period to shift
the frequency slightly (far enough to make it easily discernible - but not
so far as to drive it off the display screen) which makes a carrier which is
indistinguishable from other signals stand out clearly.
None of the above is new but is an attempt to influence the focus of the
work by you guys towards my favourite interest - ultra-narrowband reception
