Packet Radio

Good afternoon all,

  I'm trying to get a packet radio system up and running, and I don't know if it's a line-of-sight issue or a systems / user issue, but I can't seem to get up and running and am looking for anyone who might have some background info or troubleshooting tips (I'm completely new to packet).  I have an ICOM IC-2820H setup as my home base station, which I am connecting to a Coastal Chipworks TNC-X modem, to my Windows laptop.  I'm trying to connect useing RMS Express to a station in Cape St. Clair, AB3YY / 145.010.  I've also tried a couple other stations, but I can't ever seem to connect.

Anyone in the club who might offer some advice?
