Icom IC-9700 Modification European
The modification only works on European models and by removing 2 diodes the frequency can be expanded by a few MHz to the USA

IC-9700 Fan Modification
The fan in the unit does not run while the unit is in receive mode, and this appears to be a cause of significant temperature variations within the transceiver
ICOM IC-9700 Reference Injection Board
This module allows locking the ICOM IC-9700 radio transceiver internal frequency reference, to an external 49.152MHz signal
IC-9700 GPS-locking mods
As this is not a proper continuous phase-lock system, the internal 49.152 MHz TCXO reference is still subject to drift, especially when the internal fan cycles on and off
Icom 9700 GPS Interface
Icom IC-9700 2m/70cm/23cm rig and want to add GPS capability well then you are in the right place
GPS-9700 Locked Frequency Source
The GPS-9700 is a GPS Locked signal source that was designed for the Icom IC-9700 Transceiver to stabilize frequency when using narrow band weak signal modes
Icom IC-9700 frequency modification
The modification only works on European models and by removing 2 diodes the frequency can be expanded by a few MHz to the USA
Icom IC-9700 operational review
The IC-9700 is a multi modedata), three band transceiver using mostly software defined radio techniques
Solution for the IC9700 drift problem/
But the IC9700 drift a lot and does not really lock on the 10 MHz. REF input. This REF input is used like an old fashioned XTAL calibrator, the way we did in the old days with tube receivers
