YAESU FT - 1000/MP & MARK V interface

This one of numerous RTX - Sound blaster interfaces you can find on the internet, but this one include:

FSK KEYING to use with the RTTY port
DVS-2 to use the interface in AFSK mode, this include all digital modes + voice keyer
CW KEYING

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. Ted S57NDT
