In the quote you provided they are referring to the voltage when they say “no signal output level exactly one half the supply voltage…”. The output level means the voltage output level. It would make no sense to describe a power as being one half the supply voltage would it?
I can see a bit of confusion since “output level” could refer to the RF output power but in the context of the entire paragraph their statement is correct. Perhaps they should have worded it “no signal output voltage from Q9….”. The Ramsey board has a topic regarding manual errors and if you want you might post a comment about this there.
I have had to suspend further experiments on the AM 25 for now. Maybe someday in the future life’s events will get out of the way and I can get to it again, but please let us know of your results.
