It can be used either to send a beacon message or inreal time QSO mode using RS232 interface from a terminal. The speed / bandwidth is made continuously variable from a few 100Hz down to fractions of a Hz using a pot to control the settings. Which makes it useable at LF The downside is that it uses a hybrid SMT/CMT which he calls Pol yPhase or PP/MT-Hell type of modulation that does require a linear transmitter - so no high power with a switch mode Tx More details and a full description and PIC firmware download at Graham's web site http://g8haj.uk/ or specifically http://g8haj.uk/?page_id=288 Four of us using that module recently had a simultaneous full-quadplex (4 way version of duplex :-) QSO on the QO100 satellite.
