[RTTY] [MMTTY] Spot frequency

[James Colville]

Not really... If you set your rig to 10.000.00 MHz and see what you hear. If
you hear 2125 as seen as a horizontal trace on your MMTTY scope, then you
are right on frequency. If you use narrow filters, there is no way to here
the modulation that is 700 or 800 Hz away.
