Arie, You will have to ask Larry Phipps if that MMTTY stream is implemented in LP-Bridge.
RTTY via DTR is possible, but would require the "one transistor keying circuit" to drive the PTT-IN pin on the K3s ACC connector. Of course, LP-Bridge may or may not support DTR through its interface. 73, Don W3FPR On 1/22/2011 5:52 PM, Arie Kleingeld PA3A wrote: > Thanks Rich, clear answer. > > Well... > > The idea was to use LP bridge. > Send the RTTY keying via a com-port from MMTTY, and control the rest of > the K3 via another com with N1MM logger.
