[Elecraft] KAT-500 Bypass indication/operation issue

When the ATU TUNE function discovers the SWR is less than the bypass threshold, it should select "bypassed" as the tuning solution, and the KAT500 Utility should show no L or C values selected.  It should also show the "bypassed" check box.

I don't have a "standby" LED.

The "BYPASS" LED means that the ATU's mode is "BYPASSED", not that the current ATU tuning solution is "Bypassed".

When SWR is less than 1.3 (factory default), the KAT-500 should go into “BYPASS” as I understand.

The LC values and MODE (Manual) from the previously selected antenna are still shown in the config utility “Operate TAB”.

Also, the STANDBY LED has never illuminated when the SWR measurement is less than the threshold set for entering the BYPASS mode.

Firmware installed

    K3:  5.38
    KAT-500: 1.67
