Local Offset
+0,120
This setting specifies the offset of local time to UT. The time displayed by the #HH, #MM tags is
always UT (straight from the GPS, if connected). The #LH, #LM, #H2 tags display local time, offset by
the number of minutes in this setting. Positive and negative offsets can be chosen, for time zones
ahead of UT or behind UT.
Corr. threshold
050
This parameter specifies a correction threshold, which is applied when using a GPS to discipline the
oscillator. The 1 pulse per second (1pps) from the GPS continuously acts on the reference oscillator.
But the VFO frequency (and Clk1 frequency, if configured) is re-calculated using the new 27MHz
reference frequency and updated only when
a) The rotary encoder is turned, to adjust the frequency
b) The menu system is entered and exited
c) The 27MHz reference frequency differs by more than this specified correction threshold, from
the value last used to update the VFO.
The default is 50Hz. This parameter is useful because when the VFO is re-calculated it can cause
small glitches in the output frequency, which can be audible on a receiver. It can be annoying if that
happens once every second
– depending on your intended application for this kit. So this parameter
allows you to specify this tolerance threshold, so that updates are infrequent.

27,000,000
This is the value of the 27Mhz crystal reference frequency. If you are using a GPS to discipline the
oscillator (non-zero GPS mode parameter, and valid 1pps GPS signal available), this value is
updated automatically during the GPS discipline process. If you are not using a GPS (GPS Mode = 0)
then you can edit this parameter manually to calibrate your VFO/Signal Generator kit.
