[TenTec] Corsair II warble

[Bob Towers]

Thanks, Edward, for your reply.

Yes, the digital display on the Corsair will only display to 100Hz, but the waterfall displays on all the PSK programs display 100Hz markers with enough space between them to be able to see signals which are less than 50Hz apart. I can see the frequency plot of a fixed frequency signal on the waterfall and hence see the warble to an accuracy of around 10Hz.
