Hi Joe, While on the subject of the Si5351 chips, the application of converting one reference clock to a secondary frequency is what they were designed for. So, since you've already got a GPS reference, this -might- be an inexpensive starting point...For this application, you obviously won't need all the bells and whistles presented in this article! See: http://www.knology.net/~gmarcus/Si5351/Si5351_VFO_QEX.pdf http://www.knology.net/~gmarcus Note that I would replace the Si5351 25MHz reference with a decent TCXO (available on ebay, etc.)....Note that I haven't used the Si5351 with an RTCM, there may be simpler/better ways??? 73, David KB4FXC On Mon, 6 Jun 2016, Joe Moskalski wrote:
It seems clear that in order for simulcast to work properly with the RTCM I will need to clock the CPU to the GPSDO. Is there a device available to give you the 9.6 mhz reference from the 10 mhz out from the GPSDO or does anyone have a schematic available so that I can build them myself?
