When all else fails read the manual

Hi Dan, Good advice, but he has already read the on line manual, if you read
the post. The 941E must be a later version of the 941B, which he is asking
about. The only thing I can figure is; the 941E has a dual (cross hair) swr/
power meter. If the B version does not (and I don't know) the button in
question may be a forward/reverse switch, which would explain why he only gets
good readings when he pushes the button.
