Hello friends.
Use Linrad as front-end for MAP65 and WSJT.
To view an jt65
signal, on the waterfall of linrad (SSB), shift the BFO to -1270.5 and filter
to about 2.4 kHz.
The frequency in Linrad corresponds exactly to the specified
frequency of MAP65 (+/- Doppler).
The audio output from Linrad, which uses as
input for WSJT is perfectly focused (DF = 0) on the desired signal.
The
problem is that the scales of frequency of all windows of Linrad indicate a
different frequency, that is without compensation of the BFO.
It is difficult
to click on the signal desired in high resolution spectrum, especially when
there are many JT65 signals in a few kHz.
How to get the right indication on
the scales-frequency of Linrad ?
Thanks
