KX3 and KXPA100 - PA Mode Question

[Edward A. Dauer]

Coordinating the KX3 with the KXPA100 requires setting PA Mode to ON in the KX3’s configuration menu.  I noticed recently that when the system is powered down and later restarted, the PA Mode config had reset itself to OFF.  The cabling was not disconnected – the only intervention was shutting down the power supply.  Am I doing something wrong?  The cabling is correct and employs the cable sets from Elecraft.

Since the ON setting is required to get the two ATUs to behave properly, it’s an inconvenience to have to reset it to ON each time I power up . . .   Any ideas?

Thanks,

Ted, KN1CBR

Don't power off the KX3 by abruptly killing the power to it -- make sure you power it off cleanly by simultaneously pressing those two buttons on the left before switching off the power supply, otherwise the settings won't get written to NV memory properly.

When you shut down the power supply before turning off the KX3, the supply voltage drops and and the KX3 defaults to low power which means that the PA is turned off.  If you shut down the KX3 before shutting off power supply you will not have this problem.
