I can see Bob's trace on Spectran/Argo but have not had a decode yet on Opera v.1.5.3 with the radio in lower sideband mode to reach Bob's frequency below 30 KHz. This is quite a watching paint dry mode. :-) My grabber is running on Bob's frequency. 73 Jay http://lwca.org/grabbers/ka9cfd/ Jay Hainline KA9CFD Colchester, IL EN40om
