Frequency accuracy and stability become more challenging for transceivers that operate at 400 Mhz and above. Our 4.0 Satellite Stations operate at frequencies approaching 1.3 GHz and we want to be sure that their frequencies are accurate and stable. We decided to add GPSDO Freqeuncy Locking to the Icom IC-9700 in our Portable Satellite Station…

We recently added a GPS Disciplined Oscillator (GPSDO) to the IC-9700 in our Portable Satellite Station 4.1. The addition was easy to accomplish and it locks our Icom IC-9700 Transceiver’s frequencies to the very accurate and stable clock from GPS satellites.
