3. Local oscillator (PLL)

Please see schematic on my Download page

Now Local Oscillator produces 1268Mhz  signal for the transverter. At beginning I planned to use as reference oscillator, the 10Mhz TCXO (24$ cost), that can be soldered directly on LO-PLL board without any external connection, but due to significal for microwave band thermal drift, I decided to use external OCXO.
