Radio: 6400M with 126.96.36.199 Firmware
Setup: On any of the 5 60M channels, USB mode, TX filter set to Low=100 and High=1800 Front panel is connected and controlling.
Observation: Transceive works fine. However the TUNE button does not transmit and in TX Menu window briefly displays a red highlighted message, "Inhibit: Out-of-band".
Anyone else experiencing this?
