49.380 MHz. All signal sources are phase-locked to the refernce. Fine
adjustment occurs in firmware, and once calibrated, it's accurate to
about 1 Hz through 6 meters at the calibration temperature. The
high-stability option is at the same frequency, with firmware
correction to better than 0.5 ppm.
49,380,000 * 0.0000005 ppm = 24.69 Hz, and actually worse on 6 meters,
since it's a higher frequency. In any case, it's considerably worse
that the 1 Hz stated for the standard reference. Is that ppm/degree C,
over some temperature range, or ? Is the tempco specified for the
standard reference?
