It was noticed, after a time, that whenever the distortion near 

 700 '—' manifested itself, the amplitude measurer of Fig. 9 was 

 mounted on the receiver. This particular form of amplitude meas- 

 urer was described in an earlier publication. This led to the sus- 

 picion that the clamping screws in the brass frame F might be re- 

 sponsible for these distortions of the impedance circle. On actual 

 trial, the removal of the amplitude measurer and its clamping frame
