Monitoring SIDS and stations

Good Afternoon,

After setting up the SID apparatus that was sent to us by Rodney Howe, we had many trials and locations, from outside to inside on a netbook, and now moved to its permanent computer location in house.

My question is, since the antenna (75 cm loop) was tuned to NAA how can we be sure are hearing that station?  We do not have a tunner nor an oscillascope.

Is there anyway that other SID users could post thier daily run, to see if we are even close to looking like a graph should look like?

We are using the RadioShack meter, and meterview. Sampling every 5 seconds, currently the set up is running at .759 volts which I assume would be a very quiet day, since NOAA is saying everything is quiet.

We are also wondering if we can create a macro mouse event to save the data daily, then create a new file (start) , then have a command to rename the saved file to the date in UT time if this will  help with data saving. We currently use this technique in one of our other operations for an all sky camera.

Thanks

Hi Kim,

I haven't had my loop setup for several years, but the attached shows NAA traces at this time of year from a reasonably "nearby" location. Nighttime is unpredictable but the daytime pattern is pretty much the same from day to day (except for flares and the usual Monday NAA shutdown!)

Cheers,

Doug

There is a VLF receiving station which posts in realtime the signal level received from NAA.  You can compare your graphs with this station's graphs.  Also NAA goes down for maintenance (once a week ?) so you can observe this also.  Here is the URL:
