Hello George - Are you talking about RSO? It's only intermittently noisy - usually wind or other electronic interference. Signals look beautiful today. Thanks, Cheryl -------- George Makar wrote: I wonder - does the noisy station signal have a bad ground connection? The signal reminds me of a bad ground somewhere in the system. Hope you're staying warm :) George -- Cheryl Cameron Geologist, Alaska Volcano Observatory Alaska Division of Geological & Geophysical Surveys voice: 907-451-5012 fax: 907-451-5050
