[TenTec] Orion 1 Ver 2.062a Bug?

[John Huffman]

A quick check of the archives didn't turn up an answer, so I thought I'd 
ask here.

Using firmware 2.062a, if I have VFO B listening to AM broadcast and 
then push the tune button to tune on VFO A, the headphones mute and 
won't come back without turning off the radio and turning it back on.

This is a new-to-me Orion and only had it a month.  Is this behavior a 
known problem?  BTW, sweep is off.
