Hello, First, I am late with my translation to Spanish but I will have time next week (finally!).
And I've been wondering about proper gain staging in WSJT-X for optimum reception. The manual suggests adjusting the input level and RF gain until the noise level is at around 30 dB according to the program display, but at least being audio minded it's difficult to refer to some external measure. I am considering writing an article about this, giving some (hopefully useful) guidelines. I will send it to the URE magazine but I can write it in English as well and share, of course. I have some questions: Does the input level send gain adjustment orders to any USB device or is it purely a digital gain applied to the sampled signal? At least on Mac OS X I haven't observed any change in the input gain of an IC-7200 (it has a TI PCM2901E) What is supposed to be the unity gain setting for the input level slider? How does the displayed input level relate to dBFS (decibels related to full scale)? I could measure that but I am not sure about its behavior on different platforms (Windows, Linux, Mac OS X) and with different devices, so it would be great to know what it's supposed to be.
