RTTY and Audio

[Chester Alderman]

I’m wearing my poor manual out! But can’t come across what I need.

When I change to FSK D mode and using VFO A, I basically have no audio.

I have SPKRS set to 1

SPKR + PH set to YES

My SSB & CW audio is normal and clear. Is it normal for there to be only
very weak RTTY audio, even with the AF control ¾ of the way clockwise?

Hi again Tom,

No, that doesn't sound normal.

What are your DSP filter settings (shift and width), and what is your
Pitch set to in FSK D? Your filter FC should be 85 Hz above the Pitch
setting, and the BW should be 300 Hz or more (250 Hz is usable once a
strong signal is tuned in accurately, but it can be hard to find and tune
signals in with filters this narrow).

Also, do you have the Dual PB filter selected? I'd suggest leaving this
feature turned off to start out.
