[Elecraft] KX3 Firmware update trouble

[Dave Sublette]

Dick and list,

We have successfully updated the firmware for the DSP and the MCU.  The
problem occurred as we were trying to install with the KXPA100 in line.  I
removed it and connected the computer directly to the KX3 and all went
well.  Later, we were able to connect the KXPA100 and confirmed that the
KXPA100 has the latest firmware.

Thanks to Dick and all of you who monitor this list and contribute support.

73,

Dave, K4TO
