Is it possible to have JS8Call installed? Forme JS8 mode is far more important than JT9 mode as Hearteat can replace JT8 contacts and the plain use of JS8Call allows me to do real QSO with exchange of informations. I experienced a terrible civil war in New Caledonia since the 13th of May this year, with sometimes all communications lost - no more internet nor phone - and JS8Call was my only mean of communication with the outside world and it worked well with my QRP station - Hermes Lite 2 and QRP-Labs QDX which deliver 5 to 6 Watt - The small size of a zBitx with its integrated batteries would make a wonderful emergency transceiver. 

Anyway this product looks promising, congratulations f.
