Thanks Andy. It is difficult to fine tune my receiver (Lowe HF250) that closely using the front panel controls. There is a problem with the RS232 interface so I cannot do things more accurately.

7dB is OK.  0dB is the optimum, but +/-10dB on this is within range.

Pretty consistent here in Burgundy.  Shows slight drift in my receiver.
