Hi Sam, The UDP message structure for the status message packet is documented in the Network/NetworkMessage.hpp file.
Our patch adds a single new trailing field (called 'Itone Data') to the existing UDP message structure. The following code demonstrates how to parse this new 'Itone Data' field. https://github.com/kholia/py-wsjtx/blob/master/pywsjtx/wsjtx_packets.py#L243 Thanks, Dhiru On Sat, Jul 15, 2023 at 8:55 PM Sam W2JDB via wsjt-devel <wsjt-devel@lists.sourceforge.net> wrote: > > Can you supply the updated udp message structure with the new field(s). > > Thanks > > 73, > > Sam W2JDB > > > On Saturday, July 15, 2023 at 06:49:51 AM AKDT, Dhiru Kholia via wsjt-devel > <wsjt-devel@lists.sourceforge.net> wrote: > > > Hi, > > This patch adds itone data to the status message packet. > > This feature is useful for 'digital transceivers' as they NO longer need > to rely on the AFP-FSK technique, which introduces a non-zero error into > the transmitted tone values. > > While this approach is not as transparent as the AFP-FSK technique, it > eliminates the non-zero error associated with AFP-FSK. > > As an alternate approach, the 'digital transceivers' can use ft8_lib > to derive the tones from the 'm_currentMessage' data, which is already a > part of the status message packet.
