I have a GPSDO system already in my shack. Based on the 10 MHz signal, I would like to generate a 27.8516 MHz LO for my already modifed LNB (the XTAL has been removed).
Does anyone know a usable DDS board to generate the LO frequency based on the 10 MHz reference clock? I bought on ebay a board with ext. clock input, but the output signal is garbage. (Name of the product: DDS Board with ext. reference clock) Don't use it!
Thank you for any suggestion!
