YAESU FT - 1000/MP/MARK V (filed) interface - This one of numerous RTX - Sound blaster interfaces you can find on the internet, but this one include:

    If you use AFSK mode you will probably need wide and narrow filters. With the classical MP this is not a problem, but with the MARK V (field) series, if you need wide filters you use the normal SSB mode, if you need narrow filters then you use PKT mode. 

    P.S. Thanks to S56A for help!
