Waterfall much narrower than the visible range of the spectrum box

Bill Hamel

Good evening. I am new to fldigi this may just be a newbie thing.

fldigi v4.1.00
Rig: Yaesu FT-991a
OS: MAC OS X 10.13.6
Digi Mode: BPSK31

With the FT-991a mode set to DATA-LSB (or DATA-USB) the width of the waterfall goes from 700 to 1300, if I switch to LSB or USB the waterfall covers the entire spectrum area which my view currently sees from 0 to 2700.

DATA-LSB or DATA-USB is the mode required for BPSK according to the Ft-991’s manual.

Is this the expected operation ?

It seems to me that I should be seeing the entire range of the spectrum that is in view or scrollable view.

Any insight greatly appreciated.

This is what I’m seeing.



Thank you in advance,
Bill Hamel, K3TFM
