Thanks Bean.

I made a slight change to the Main routine:

FOR index = 0 to 100
	TX_BYTE "A"
	DELAY 2
	TX_BYTE $20
	DELAY 10
NEXT

On hyperterminal I receive 100 "5f 03" bytes

So it seems data is coming in, just the wrong value consistently arrives!

Can that point to the need for a max232, or should it be something else? I mean, that I would really prefer just to use the sx28, and the fact that 100 bytes are coming in consistently might suggest the voltage is not the issue here? ... or maybe it does...

Thanks, Max
