Dick----congrats your little toy has MODE S. In most places around this place we affectionately call the GAFFA it won't be seen anyway........
GAFFA because it contains fark all radar coverage....so call it GAFFAR
That's were the ADSB will work but you will be stuck at FL280 being procedurally separated. Enjoy the extra fuel burn that comes with stubbornness.
Maybe you could promise Airservices that you'll only fly in areas with 100% radar coverage, that should give you a little area to play in..
