First, I'm not familiar with the ATS 909X, but if you're asking if the firmware can be reflashed, I think contacting Sangean directly would be the best approach.

Second, maybe the problems are caused by such things as poor connections or a cracked circuit board. Sometimes problems such as these are sensitive to twisting or otherwise stressing the case. A useful clue. If you haven't done these sorts or repairs, it's worth remembering that it's easier to make things worse than it is to make them better.

It's also a Radio Shack DX-398

Hi J.C.
Thanks for your answer.
Are you talking about Sangean ATS 909X?

You said: The SSB control is not a "Button"!
The ATS 909X has a button to switch from AM to SSB. See photo.
I am talking about this button. I did not talk about the fine tune or SSB control. The SSB button does not work as described on the "Sangean ATS 909x" manual.

You said: "One then needs a SOURCE of SSB broadcast"
I am a ham radio, call sign PU2CLR. Believe me, I know how to listen to LSB and USB stations on my radios.

Anyway, thanks for trying to help me.
