[Yaesu] FT-857D IF filters

[Michael Clarson]

David: You install the filter in one of the available slots. Then, from
either Multifunction Row "n" or Menu Mode 86, select the filter you want.
When you look at the FSK mode (Menu Mode 038) should be RTTY-L. Then, when
you select digital mode, the filter will be in the correct part of the
passband for RTTY AFSK. If you are using MMTTY, you may have to move the
tones around slightly to center them in the filter passband. You can select
any of the three possible filters when in the DIG mode. The passband is
already shifted for RTTY. There are ways to change that, but you shouldn't
have to. --Mike, WV2ZOW
