Jeffrey. Yes use the enhanced CP2105 usb-uart comport for CAT, this just enables frequency read for the built-in logging using the compatible FT-991 profile.

See device manager to id this pair of CP2105 comports on the one usb connection.

The other standard CP2105 usb-uart comport is used for the PTT via DTR, and FSK via RTS, as you see in the screenshots on link below.

https://www.qsl.net/ja7ude/extfsk/indexe.html  << Important for EXTFSK64 setup.

The method id the same for the FTDX101

Use RTTY-L mode

ON radio set > FUNC > Radio Setting > RTTY RPTT Select = DTR

Other RTTY settings are left as default (yellow font)

Use about 20 KHz span, and monitor on.

You will see both the mark/space lines on TX , also hearing the diddle with monitor on.

ALC will be high 70% or more of white scale, normal with FSK keying.

Adrian, thank you.  I am not familiar with rxtFSK64?  Do I need to install something else to run along side of MMTTY?  I see a COM2 & COM17 - is there additional COM ports that need to be created?  Thanks,  Jeff / K1ZN
