Just to add (and not referring directly to any measurements you may have made) that many discrepancies in measurements are the result of not following the service manual specifics regarding test conditions. A properly prepared SM will include the conditions of measurement - such as line voltage, warm up time, impedance of the meter, whether or not a signal is applied, setting of customer controls and service adjustments and placement of switches or functions selected. There are others I'm sure.

Yep. Try aligning any of several multi-band radios without following the manual - and see how far you get.
