Hi Alan: I certainly understand your reasons for nervousness here. However, I would like to express how much this "unofficial" feature has been helpful to me in setting TX equalizers for three different mic settings (macro driven) and two mics (front and rear). And I often return and tinker with these settings for optimization. In my P3 the "feature" works well, but right now it is clumsy to use, to say the least.
Here is what I have to do: Open Config Menu: RS232 which will read 38000. Attach a dummy load (or tune to an empty spot in the band). Turn on Peak hold, then right away turn RS232 speed to 4800 (this is equivalent to removing the cable), talk into the mic, and then tap freeze to look at the cumulative audio spectrum! Set to a narrow span (I use 4khz) one gets a lot of good detailed data this way, but is it a bit of a fiddle! If you want to do it again, start over. Alan, I know there are interesting options coming down the line with some additional hardware required (what else is the "sensor" opening at the back for?) But in the meantime, the "unofficial" feature is very useful indeed! Thanks so much for the fine panadapter. It has proven itself to be more useful than I thought it would be.
