The GPS-9700 is an external signal source that was developed for the Icom IC-9700 Transceiver to stabilize frequency when using narrow band weak signal modes. The GPS-9700 can be used with or without an external 10MHz reference input to make a IC-9700 frequency stable on all weak signal modes including on the 23cm band.  For frequency accuracy, it is suggested that the GPS-9700 is locked to a high quality external  GPS derived 10MHz frequency reference.  The design incorporates a 0.28ppm low phase noise 49.152MHz Voltage Controlled Temperature Controlled Crystal Oscillator ( VCTCXO ) reference which is amplified, and filtered to produce a very clean RF output.    The signal is then injected into the IC-9700’s internal 49.152MHz frequency reference using a small coupler PC board to mode lock the frequency.

Please Note: Built products usually need to be constructed and can take up to 2 weeks to ship depending on work load, but are normally shipped in few days.


The Product image shows a fully constructed PCB Module board GPS-9700-MOD.  Please refer to the Options Tab for the descriptions of the various products available.

GPS-9700 KIT is a basic Kit that includes the PC board, construction notes, and all on board components and coupler board. This Kit does not include the SMA connectors or enclosure. Requires complete construction and soldering of small SMD components.

GPS-9700-MOD is a fully constructed module board with SMA connectors and coupler module board.

GPS-9700-1455C is a fully constructed product in the Hammond 1455C enclosure with the coupler module board.

If you are constructing the basic Kit and require the enclosure, then you will need to order the Optional 2x SMA39 connectors and the Hammond ENCL-1455C enclosure.  All products include the coupler board and a 2.1mm DC power cable.  The Kit Product is for Advanced constructors that have very skilled soldering skills.
