[digitalradio] No PTT, FLDIGI with ICom 746P and Digikeyer

[Andrew O'Brien]

I am trying to help a friend set-up FLDIGI on his new laptop using his 
Microham Digikeyer.  Using the device router for the digikeyer (control 
port 5 and PTT port 6) the digikeyer PTT test button does toggle the 
PTT.  However when using FL-Digi , frequency display corresponds with 
the Icom 746 but the T/R button fails to place the Icom in to transmit 
mode.  Any ideas ?  When configuring FL-DIGI, we did try to use HAMLIB 
and PTT via CAT control, but that did not produce a PTT wither.
