You might need to confirm proper action of the attenuators.
If you do no know the complete history of this generator (did someone inadvertantly transmitt into it and over-dissapate one of the resistors) then this is something that I myself would do so I would have more confidence with the end result.
This unit is aged so switch contacts could be an issue.
I would generate a S9 signal and then compare signal level drops between the 4 "20 db" attenuator sections.
Then move on to the "10 db" and the "6 db" sections and see if the drops associated with those sections are consistent with their numbers.
While you are doing this you will also be characterizing the Smeter on the radio.
Let us know the results.
It is normal for a non commercial generator to drift some.
It might not be possible to do the SINAD adjustment while in the sideband mode on the radio.
What mode have been in while trying to use the generator with the radio...... I guess I have assumed that you were in AM mode.
Thank you
