I received the parts on Saturday and had time to install the additions this morning. I ran the ‘standard’ frequency scan from this thread. For reference it uses a gain of 29.7. Here are the main results.
You can see the filter/amplifier is working but the gain of 29.7 used for this scan test is probably too high. Before running FA I checked the strong message percent which was 48% at a gain of 49.6, up from 4% prior to the change. I immediately lowered the gain to 38.6 which still had a strong message rate of 24%. I’m letting it run at this gain for awhile to gather a bit of a baseline. Then I plan to lower it for further testing. The weather this week won’t have idea flying conditions so a final assessment on gain and effectiveness will take some time.
