'Morning Dave
It shows -7 however I am not sure how that is based. Here's the produced chart:
Below is the original on this unit:
I'm pretty sure that these displays are meant to be just relative measurements since the amplitude parameters seem to change with various settings. The proof was the bench results. Those I can control the conditions. On-the-air performance is now quite nice, I am hearing the weak ones and the normal background noise. The only artifacts present are the ones that I had before the modification but, then again, I am in a rural area where I can expect to be able to sneak by without a receive band-pass filter.
