[KX3] OFS/VFO B Knob Muting in Text Decode

[Mercury]

I searched the archives and could not find reference to the following issue I've observed on my KX3:

I don't normally use the text decode feature but was playing with it today and noticed that rotating the OFS/VFO B knob after setting TEXT DECODE resulted in strong muting of the receiver. The muting appears to be related to the knob rotation rather than the specific setting selected. I first noticed it when changing from TX ONLY to RX THR1 but experimentation revealed that even turning the knob counterclockwise while displaying DEC OFF would mute the receiver. It sometimes took rotation through two settings such as from TX ONLY to RX THR2, or counterclockwise through two "clicks" while on DEC OFF to mute. Once muted the receiver remained muted as the knob was rotated and could only be corrected by unsetting and re-setting TEXT DECODE or tapping ATU TUN. The muting occurs even when the ATU is bypassed or when NOT INST is selected. This requires cycling power to recover normal receive levels. The muting is severe, with the resulting audio level between the normal ATT 20db redu
 ction and disconnecting the antenna. Setting ATT while muted has no effect on audio level. I hear a popping noise in the audio with every selection of the OFS/VFO B knob when in TEXT DECODE mode only (no noise when rotating through menu selections or any other mode that I have used).

Has anyone else experienced this? Can anyone give me a suggestion as to what might be the problem?

Thanks,

William, AI4VE
