Unplug the the frequency display and see if the signal goes away. The signal  is coming from that unit. Verify it first and the decouple the vcc going into the display unit

It's definitely not a 25 kHz or 100 kHz crystal calibrator.  It's continuously there with no means to turn it on/off.  I thought that perhaps it's a third-party add-on unit or perhaps a homebrew mod, but I don't see anything that would indicate either.
