I have an FT-890/AT which I like very much for CW and
the built-in antenna tuner. One shortcoming of this rig
is that it does not include FSK or allow using the 500Hz
filter in RTTY (that I know of).
Running AFSK is not troublesome to me and the rig does
provide a nice DATA IN/OUT jack on the rear. It works
great on all digital modes with the FL-7000 QSK amp.
Is there ANY way to use the 500Hz filter for RTTY/Digital?
How have others overcome this? I use a DSP audio filter but
I beleive an IF filter would be better.
Any discussion of any type on this subject? I am very
interested to hear ANY comments.
