MCU 2.73 / DSP 1.98, 12-9-2008
* RX EQ is now applied to both main and sub receivers.
* TUNE NO LONGER CANCELS AUTO-NOTCH.
* CONFIG:ADC REF MENU ENTRY: This allows the operator to calibrate
the voltage reference used by the K3 to measure and display certain
values,
such as the rig’s supply voltage. ADC REF calibration is optional but
recommended. First, disconnect anything attached to the ACC jack. Next,
locate the CONFIG:ADC REF menu entry. It will initially show 5.00 volts
as
the reference voltage. Using a DMM set to DC volts, measure the actual
voltage at pin 2 of the ACC jack. This must be done while the ADC REF
parameter is being displayed. (The (-) probe of the DMM should go to
the K3’s chassis ground, e.g. the GROUND lug.) Finally, use VFO A
to set the ADC REF menu parameter to what you measure at pin 2.
For software developers:
* “CP” COMMAND ADDED (speech compression setting).
* Auto-report (AI2 mode) added for the “MG” command (mic gain).
