KRC2 Accessibility Configuration Operation
The KRC2 with the Accessibility Configuration gives the K2 a Morse code voice to announce its
status and operational characteristics. The KRC2 may be set up to automatically announce changes
in the K2’s settings, including the announcement of the operating frequency whenever it changes.
The user may control the amount of chatter generated by the KRC2 by setting it to one of four
‘verbosity’ levels. The lowest level requires the user to press the KRC2’s keys in order to
announce K2 information, while the highest sends out Morse text whenever almost any parameter
changes on the K2, including the frequency. Additional button combinations allow the user to
control K2 operations and also those of the KRC2 itself.
Accessibility Configuration Key Behavior
There are four buttons in a row on the top of the KRC2, labeled, from left to right, F1, F2, F3 and
F4. In the accessibility configuration, the F1-F4 buttons have the following TAP,
HOL D and
HOL D TAP (shift) functions:
F 1 Announce the kilohertz portion of the current K2 frequency.
F 2 Announce the K2 LCD display text.
F 3 Announce the K2 S-Meter level.
F 4 Place K2 in direct frequency entry mode.
F 1 Holding this button will cause a Morse ‘I’ to be announced and the KRC2 to enter
shift-1 condition. Tapping a button will then cause one of the functions listed below
to be performed.
F 1 Announce the megahertz portion of the current K2 frequency.
F 2 Toggle Fine RIT mode.
F 3 Announce RIT status.
F 4 Announce XIT status.
Holding F 1 instead of tapping a key will again announce a Morse ‘I’, but will cancel
the shift-1 condition.
F 2 Holding this button will cause a Morse ‘I’ to be announced and the KRC2 to enter
shift-2 condition. Tapping a button will then cause one of the functions listed below
to be performed.
F 1 Announce AGC status.
F 2 Toggle RxAnt on/off.
F 3 Toggle KDSP2 Noise Reduction on/off.
F 4 Toggle KDSP2 noise Threshold on/off (USB/LSB modes only).
Holding F 2 instead of tapping a key will again announce a Morse ‘I’, but will cancel
the shift-2 condition.
The KDSP2 control functions require the K2 to have firmware version 2.04 or higher and the
KDSP2 to have control firmware version 3.10 or higher.
