I have three mountain top APRS wx stations on the air, W4SNA-2, W4SNA-3 and W4SNA-4. W4SNA-2 is on Sauratown Mountain about 20 miles NNW of Winston-Salem, NC. W4SNA-3 is on Pops Peak near Fancy Gap, VA. W4SNA-4 is on Young Mountain about 15 miles NW of Salisbury, NC. Local igates send the wx data to APRS-IS. The data can be viewed on findu.com or aprs.fi. The stations do not participate in CWOP.
