Precision Frequency Reference for IC-706MKIIG

Installed Xref-VT board on my ICOM 706MKIIG. The board is obtained from VK3HZ . The XRef-VT take a 10 MHz reference signal from a GPS reference or other high accuracy source and provide a precision reference frequency.  This eliminates the problem of radio being off frequency and drifting as it warms up.  If the 10 MHz reference signal is not available, the board reverts to using its onboard TCXO as its source. In the case of the Icom IC-706 MKIIG, the reference frequency is 30.0 MHz. For more information go to VK3HZ page.
