I have one of the first US Core models.



In addition to the problem with range, there is also a serious problem (imo) with presentation. My butterfly display (and so far as I know all of the flarm displays) simply gives a circle and a relative altitude. It's completely useless to me. What would be vastly better is digital presentation of range and relative altitude (like Zaon) and trend indicators on both range and altitude (I think Zaon only indicates trend on alt).

I would also be useful if it would show the code they are squawking i.e.

1200 - A VFR aircraft
1202 - Another Glider
02xx - A local IFR aircraft talking to the Local ATC.
03xx - A local VFR aircraft talking to the Local ATC.
43xx - Likely an Airliner or Jet.
