For an expensive meter, I must admit I'm somewhat disappointed. I used it to find E* 61.5 and while I was able to find the bird fairly easy, the PQ reading was numerical only - - no PQ progress bar. Until I noticed the numerical only readout, I was wasting time.
Now to the 97 bird. Even though the receiver showed poor PQ and many channels were unavailable, I was not able to get any reading on the 4000 except the top signal strength bar had minor variations when trying to peak the dish. Out of frustration I moved it to the 95 bird and presto! I was able to peak 95. Then I tried 101 and again presto!, I was quickly able to peak 101. Something is wrong.
Also, I'm still unable to figure out what the PQ calibration really does and have not found an explanation. It would be nice if some defaults for various footprint contours of common birds were listed.
