Commit:81ab679fbd94c263068019ce9084cc7bfb4b9518
Message:The parasitic capacitance of the three probe input pins and R1 formed a quite formidable low-pass filter that almost completely eliminated the 1 MHz signal.

- cntr/cntr.sch, cntr/cntr.brd: changed R1 from 100k to 1k to increase
input bandwidth
