LXNAV with Flarm doesn't work in US

[Jonathan St. Cloud]

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

Flarm transceivers operate on a different frequency in Europe, and, even if it can be reprogrammed to operate on US frequency, it does not have the necessary FCC certification.

The LX90X without Flarm series does have a connector on the main cable (binder 5 pin) to connect with a PowerFlarm US with a lx5pf-ca cable.

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.

The short answer is the integral Flarm in all the LX computers does work in the USA. The GPS recognizes your location and sets the Flarm to the correct frequency for North America.

However, as stated above, it is not legal to use them in the US because they are not FCC approved.

And, in USA, they will have greatly reduced range as compared to
performance in Europe or compared to PowerFLARM.

Please do not use the legacy FLARM units in USA.

Hope that helps,
