Well I received my dAISY in the post today, and have fired it up. I'm around 5km from the coast, in an office, so poor to no coverage here, but the dAISY is outputting:
sync A RSSI=-100dBm
error: invalid stuff bit
sync A RSSI=-100dBm
error: CRC error
So, I think everything is working as it should, I just need to get home and set this up in its more permanent home. I'll keep you posted with updates.
