I asked what the black button on the back marked A/W is for, but I didn't get an answer. A simple manual would be appreciated.

The only complaint I have is the banana jacks, they should have been of better quality, thats just a little tip from me

Arrived perfectly. Functioning flawlessly. Only the DC cable fits a bit tightly in the socket, but that can be changed.

Tune in well. Pull the antenna tuned to the center of the band from the edge of the band.
