Hi Jonathan,

Good question. There are several reasons why "Classic FLARM" units (like
those built-into LXNAV LX80x0 and LX90x0 products) shouldn't be used in the
USA.

- Classic FLARM devices do not have F.C.C. approval (and never will) - so it
is illegal to use them in the USA.
- The Classic FLARM devices use different frequencies than we use in the
USA. The software probably automatically switches to the U.S. FLARM
frequency, but the antenna lengths are not ideal - so range will be
limited - which is bad.
- If I remember correctly, the PowerFLARM units sold in the USA have
slightly modified circuitry to optimize range on the U.S. frequencies -
making them work less well in other countries.

You can connect a U.S. PowerFLARM Core or PowerFLARM Portable to an LX80x0
or LX90x0 unit. I have several cable options available on my LXNAV web
page. I am using a PowerFLARM Core with an LX9000. It works great.

Just curious why the integrated Flarm in the LX 90XX series will not work in
the United States?
