Measuring Frequency using Demo Brd and jm_frequency_counter.spin

I get spurious results when measuring the frequency of a CTS MXO 50-2 1.8432MHz oscillator with TTL compatible output using the Prop Demo Board and the jm_frequency_counter.spin program. The Prop shows !.818181.8 with the last 6 digits fluctuating irradically. My Leader LDC 824S counter shows the oscillator to be rock solid at 184320x except for at most +/- 1 Hz while connected to the Prop through a 330 ohm resister. The oscillator is attached to pin 0, +5v and gnd on the Demo board.
Is the problem in my connection, in the spin program or in none of the above?
