Here are some tests done by DG8SAQ with and without those resistors at the input to the mixer.
This from the above link: ¡°Apparently, by bridging R43, R44 one can obtain a match closer to 50
Ohms while obtaining 30% more audio signal.¡±
John,
Ah! I was thinking of the other 10 ohm resistors in the op-amp inputs.
But will the reasons for and effects of these resistors be similar?
And that reminds me that Tony began to use lower-noise op-amps. That DID increase sensitivity.
