Change History

Rev. E, Feb.. 3, 2004 (In conjunction with K2 MCU firmware rev. 2.04)

 Release 2.04 K2 firmware adds 60-meter support (requires K60XV option), 6 transverter bands (vs. 3), low-

level transverter I/O support (requires K60XV), and two new scanning modes. Most of these features are

accessible via RS232 commands. See the latest K2 Rev 2 Firmware instruction sheet for full details.

 The UP and DN commands can now be used to scroll or change parameter values in the menu. This should be

especially useful as a way to automate BFO and filter setups in C A L F I L . Previously, there was no way to

vary the BFO or filter parameters via RS232 commands.

 Added TQ (transmit query) command, GET only. Returns 0 if the K2 is in receive mode, 1 if in transmit mode.

This is the preferred way to check RX/TX status.

 Added SW80 and SW81 commands. These emulate 2-button combinations

A F I L +S P L I T (KDSP2 notch

filtering on/off) and

A F I L +R E C (KDSP2 noise reduction on/off). Displays N O T I N S T on the K2 LCD if

the KDSP2 firmware revision in use does not support the command, and an all-blank display if used with a

KAF2.

 Improved RC command (RIT Clear). This command previously had no effect during transmit. In the new

firmware revision, the occurrence of an RC command during transmit sets a clear_pending flag, so that the

RIT/XIT offset can be cleared as soon as the K2 returns to receive mode, however briefly. The effect of the RC

command will be delayed by some amount, varying with the keying speed and whether the operator un-keys

briefly between characters. Also, an unknown command indication will still be returned by the K2 in this case

(?;).

Rev. D, May 15, 2002

 The description of mode AI2 incorrectly stated that the radio would send back an MD response when the mode

button is pressed. The radio actually sends an IF response, which includes mode data.

 Release 2.02E of the K2 firmware adds a new field to the extended form of the PC (power control) SET

command (page PC (Power Output Level; GET/SET)). This can be used with the K2/100 to select QRP (0.1-

15.0 W) or QRO (1-110 W) ranges.
