Elecraft KX3 firmware v1.95

MCU 1.95 / DSP 1.28

• TX RF DELAY MENU ENTRY ADDED: You can now vary the delay in milliseconds between key-down and RF output. This is useful with external power amplifiers h​aving slow T/R relays. There are actually two TX DLY settings, one for HF-6 meters and the other for transverter bands. To set the delay, use MENU: TX DLY. The “NOR” setting 5 ms; this is the recommended setting when using the KX3 (and KXPA100, if applicable) without a following high-power amp. A delay of up to 20 ms can be set for slower amps. Use the smallest delay possible. Longer delays can add some timing variation in CW mode at higher code speeds.
• NO POWER SPIKE WITH “TUN PWR” MENU ENTRY AND KXPA10​0: The TUN PWR menu entry can be used to set up a TUNE-switch power level of 10 W or less. If a KXPA100 is attached, it will now immediately be bypassed, in the TUN PWR case, when TUNE is used. Previously, if the PWR knob was set for something higher than 10 W, using TUNE with the TUN PWR feature would result in a brief high-power spike at the KXPA100 output. This has been corrected.
