Hi All,

I'm wondering if anyone has also experienced susceptibility with the Tait TB9100 reciters going in to an alarm status 'Synthesizer out of lock Digital', particularly on warmer days? Simulating the warmer day environmental conditions with a heatgun on a very low setting, it seems to me that the 40MHz VCXO on the digital board is failing when it becomes warm. Has anyone else experienced this problem? I'm considering replacing the 40MHz VCXO to remedy the issue. Any advice or knowledge of this TB9100 issue is appreciated.
