Andy, et al, re: logging program=
 
I just plugged in the G3PLX program and it is al= ready=20 collecting data on 5290...
 
Will you be on tonight??   503.700kc&n= bsp; (=20 502.200 usb ) ?
 
If so I'll leave it parked on you all night with= -240=20 seconds delay.
 
Where do I find the logs stored when session is=20 over??
