Elecraft KX3 firmware v2.08

MCU 2.08 / DSP 1.30

• MORE ACCURATE KXPA100 “TUNE” POWER OUTPUT (PA ALC): More accurate control of the KXPA100s power output during TUNE from the KX3 (PA ALC) now applies up to 70 W (60 W on 6 meters). Above this point, KXPA100 drive is still estimated based on the 75-W factory calibration. This prevents accidental over​drive in conditions sometimes found during full-power portable or mobile operation, such as high SWR, high current, etc. NOTES: (1) To disable PA ALC, locate MENU: PA MODE, then tap 1 (PRE) until you see “PA ALC-”. (2) PA ALC only applies during TUNE, not during normal transmit. Also, if you change bands or adjust PWR, and want to fine-tune the KXPA100s power output again, youll need​ to do another TUNE. (3) PA ALC does not apply if TUN PWR is in effect, since its limit is 10 W, bypassing the amp.
• KXPA100 TRANSIENT FAULT DISPLAY: Common KXPA100 faults requiring operator notification, such as high SWR, are always reported on the KX3s display. Transient faults such as serial port errors are normally not displayed, since they rarely impact operation. For diagnostic purposes, such faults can now be displayed as “FAULT nnn” where nnn is a 3-digit number originating from the KXPA100. To enable this mode, go into the KX3s PA MODE menu entry and tap 6 (DLY) until you see “XFAULT+”.
• FULL SUPPORT FOR PX3 PANADAPTER.
