I'm about to start folding the TDMA code that Sam Leffler wrote into pfSense.
The result will be available to all (it will be part of pfSense), but I need a remote test site.
I live near the top of Halekoa Drive. I can 'see' Koko Crater, Koko Head and Diamond Head. I can see large swaths of Kahala.
I have all the gear necessary.
