Stu,

Â*For example, does the SoftRf understand the Flarm Frequency hopping?

At first, channel hopping (CH) is more "radio signal obstruction clearance" rather than "security" feature.
Second: CH is not a factor for major FLARM's EU market ( only 2 channels are in use ), but "is"
for North (65 channels) and South America / Australia (24 channels).

"FLARM-alike" OGN CH was implemented in March'17 by Pawel Jalocha - leading developer
of OGN tracker. According to this source ( http://wiki.glidernet.org/history ), he had
relations with Flarm Technology GmbH in past.
SoftRF had adopted OGN CH algorithm.

Is OGN CH equal to FLARM CH in North America?
There were no neither positive nor negative reports from NA's SoftRF
builders till today.
So you have a chance to be the first one who will answer this question.

Interesting project. Just out of curiosity, are you at all looking into supporting a dual band ADS-B receiver to handle both UAT and 1090 ADS-b in the states?
