-The VCO needs extra capacitance added to allow it to operate on the Airband. Have a close look at the RX VCO. There is a small chip cap mounted where the vacant pads are located in the E band version. On the receive VCO place a 5.6pF smd cap accross this cap. See photo 1.+The VCO needs extra capacitance added to allow it to operate on the Airband. Have a close look at the RX VCO.
