Measured K2; 14 MHz with 400 Hz BW using XG3 and Fluke 87V (True RMS
with averaging mode). With full AF gain, the two -107 dBm / off voltages
were 322.3 mV and 12.5 mV, => -135.2 dB MDS

K2 sidetone pitch is 600 Hz.

AGC ON, 50 uV input sets one LED segment above S9

Using a new Rigol DG1023Z, set to 13.8 mVPP and a VNWA measured 73.78 dB
attenuator. 12.6 / 368.4 => -136.3 dB MDS. The 1023 accuracy is +-1mV,
or about +-0.65 dB.
