[Elecraft] Cannot get K3 into USB

[Keith Heimbold]

I ran into an issue this morning when trying to get on 6m that the K3 won't allow me to get on USB.  All modes are accessible besides USB. I then switched to 10m and it was doing the same thing. 

On 12m and below the USB selection works. I reloaded firmware but it is still not working.

Last night it was acting glitchy after I was having a long QSO on 2m using the internal transverter. Even when I switched to 40m where by itself it changed frequencies during a QSO.

Any thoughts on what might be going on would be appreciated.

Thanks,

Keith
