[Elecraft] [K3] K3 Audio Response - Version 3.33 Firmware

[Ignacy]

Is this measured with high impedance probes? If I remember correctly, small
caps limit low-frequency response of K3 especially with low impedance
phones/speakers.

As a further experiment, I just added 3 dB to Rx bands 1-3 and the response
is now essentially +/- 0dB between 20Hz and 3.5 kHz in SSB through the 6K
filter and Fc = 1.35.  You can lay the ruler flat on the response.
