Grabber
Images captured via Spectrum Lab with a current focus on the 2200m band (135.7kHz to 137.8kHz).
Images are from QF44mp with an IC-718 and a PA0RDT Mini Whip antenna some 8m above the ground. This is a suburban environment in a bit of a valley (hills really on all sides).
Due to the nature of Posterous page templates etc. I've not figured out how to refresh this page automaticaly (ie. with the normal http metadata). So you'll need to refresh manually as you require. Currently a new image is available every 10 minutes.
However, I do have a plain HTML page that will automatically refresh here.
You may also find these grabbers of interest:
As you'll note, the current grabber is narrowed in on 400Hz (137.4 to 137.8 kHz) of the LF band - however this changes according to what I'm playing with. This is to attempt to have as much resolution as possible for the weak signals which are also most likely to be in the Narrow Band/Digital/QRSS segment of the band - according to the VK Band Plan. Many of the above grabbers are even narrower centering right on 137.777kHz which is known to be most active for QRSS.
