The RTCM manual is a little vague on the GPS part of the setup. Normally, with other types of radio simulcast products (which I am very familiar with several) all you need to properly time the audio is a 1 pps signal from the GPS reference. The RTCM manual makes mention of the NMEA/TSIP data being connected but does not explicitly say if that serial data is needed or if only the 1 pps is needed for simulcast operation. From the other simulcast products I have worked with, you set your bulk delay to a value larger then the delay required for the furthest site and the system will adjust. Does the RTCM version of simulcast work the same way? I just want to be sure because this will determine what type of GPS locked reference oscillator I choose for the project. <br><br></div>Regards,<br></div>KC2IRV<br></div>-Joe<br></div><div id="DDB4FAA8-2DD7-40BB-A1B8-4E2AA1F9FDF2"><br>
