[Elecraft] KPA500 strange response

[Harlan Sherriff]

No matter how I change bands (k3, KPA front panel switches, or KPA utility), if I select 20m band, the KPA front panel displays 21.1. If the K3 is turned off, the KPA responds correctly to front panel switches or utility buttons. I have reloaded both K3 and KPA firmware to no avail. If I send rf out, the KPA switches to and displays the 20m band. Any ideas?
