Wayne set the open spot on a frequency that allows operation of hotspot around 434.135 I think but check with the band plans.
So go to the modem tab on the open spots browser and set the frequency and put it in dstar....
Go to the connector tab page set frequency again to the same one as the modem, and input call sign where needed.
Also set the radio set on the same frequency, Dstar is the easiest to do trust me
If the open spot is near the radio set tx low and preferably run the radio into a dummy load near the openspot.
Great little gadget any issues let me know and join the shark forum loads of info on there that helped me.
If you really get swamped let me know we can run it through on the blower.
