Help Links up but no communication

Hi I finally downloaded file. went through all the setup, and plugged in all of the devices and Yes the blue light came on and I keyed up my DV Dongle and went to REF030C keyed up and it says I am linked. its really quiet out there so I did a radio check and no one out there I also checked other Reflectors and no noise. I can do an echo and it comes right back to me. This unit was on my laptop and worked flawlessly but I din't want to tie up a laptop. My only intranet is Verizon Jet pack. not sure were I went wrong. Any thoughts? I know i am close but its not there yet.  Thanks Danny in Winnemucca
