Re: d4d off frequency

Ron,

If you measure by a frequency counter or other devices with a probe, the capacitance introduced by the probe will pull low the oscillator frequency, and 2kHz is a reasonable number.

You can receive the same station using D4D and a known calibrated commercial radio to know the difference.

Thanks,
Adam
