(Advanced) Provides a delay between release of PTT and dropping of the
transmit carrier; intended for use with fast turn-around data protocols such as
AMTOR and PacTOR. (No effect in CW, FSK D, or PSK D modes.)
A value of 20 or higher may be needed to ensure accurate data transmission with
these protocols. If sync data or – S is in effect (see SYNC DT), a lower value,
typically 10 to 12, is optimal. Also see AMTOR/PacTOR (pg. 34).
If set to NOR, the power level on each band follows the present setting of the
PWR control. If set to PER-BAND, the power level is saved on each band. This
is especially useful with external amplifiers (see ALC discussion on page 82.)
If a KPA500 is connected to the K3S via the ACC cable, two sets of per-band
power settings are saved: one for “barefoot” operation, one for use with the amp.
When the amp is used, an asterisk appears as PWR is rotated (e.g. 30 W*).
Tap 1 to LOCK or UNLOCK the MIC, CMP, and PWR controls.
Used to calibrate the reference oscillator. VFO A is used to set the reference
oscillator frequency in Hz. Typically it will be 49380.000 +/- 1000 Hz. Refer to
page 53 for manual reference oscillator calibration details.
If a K3EXREF option is installed and connected to an external 10-MHz reference,
tap 2 to enable it (XREF IN).
With a K3EXREF option installed and an external reference connected, the REF
CAL parameter will be calibrated automatically about 10-15 seconds after power-
up. An asterisk will appear in the menu entry name (e.g. REF*CAL); the asterisk
flashes as long as data is being received from the K3EXREF. Tapping 1 saves
the automatically derived value as the default (manual) value. This is not
required, but is useful if the external reference is ever disconnected.
NOR enables detection of high RFI at the antenna in receive mode (see HI RFI
warning, Troubleshooting). Set to OFF to disable the warning.
When this parameter is set to “UNDO ON”, tapping RIT/XIT CLR will alternate
between 0.00 and the present RIT/XIT offset, if any.
RS232 communications rate in bits per second (bps) or USB port selection. If
USB is selected, PC control must be done via the USB port; the USB cable can
also handle line-level audio in/out, eliminating the need for a sound card in the PC
and associated cables. If USB is not selected, PC control can be done via the
RS232/P3 jack (RJ45) as described on pg. 19.
Note: During firmware download (via K3 Utility), the baud rate is set
automatically to 38400 baud (applies to both RS232 and USB ports). The baud
rate is then restored to the value selected in this menu entry.
Serial number of your K3S, e.g. 10000. Cannot be changed.
