Transmit bias constants. See Transmit Bias, pg. 39.
Transmit speech compression (SSB mode). A setting of 20 (dB) is a good
compromise between SSB signal talk power (“punch”) and good fidelity. Set to 0
(default) when doing 2-tone IMD testing. Note: TX CMP is automatically set to 0
in audio data modes (DATA A and AFSK A).
Used at the factory to null the transmit carrier on each band. See pg. 40.
Varies the delay in milliseconds between key-down and RF output. This is useful
with external power amplifiers having slow T/R relays. (Use NOR with the
KXPA100 if there is no following higher-power amplifier.) There are two TX DLY
settings: one for HF-10 m and the other for transverter bands. NOR (5 ms) is
recommended in most cases. A delay of up to 20 ms can be set, but use the
smallest delay possible since longer delays can add some timing variation in CW
mode at higher code speeds.
Transmit audio graphic equalizer (applies to SSB mode only). Functions the same
as RX EQ, above. TX EQ can be adjusted during transmit.
Do not use high settings of TX EQ without carefully monitoring your
signal. Most microphones, including the Elecraft MH3, will provide good
audio quality with little or no TX EQ. High settings can cause distortion.
Shows whether transmit ALC (automatic level control) is enabled, along with the
transmit gain constant for the present band (nn). The gain constant is updated
whenever the TUNE function is used at exactly 6.0 W and SWR is 2.0:1 or lower.
See Transmit Gain calibration procedure, pg. 39.
If a KXPA100 amplifier is connected via the remote-control cable, PA MODE is
ON, and PWR is 10 W or higher, the TX GAIN parameter shows the KX2 drive
level for 75 W output at the KXPA100. If the drive value is preceded by the letter
‘A’, it was obtained from the KXPA100 (factory calibration value). If the drive
value is preceded by the letter ‘t’, it was obtained by doing P out CAL at 75 W at
the KX2 itself (see MENU:PA MODE). Holding CLR will erase the KX2’s CAL
value on the present band, restoring the ‘A’ value (from the KXPA100).
This menu entry is also used to turn transmit ALC on/off. It can be turned off for
transmit testing purposes by tapping ATU while in this menu entry. (This is NOT
