I'm happy to report that the Reverse Beacon Network made 312,867 spots
in the 34 hours of the IARU Contest. On average, each active Reverse
Beacon was spotting 7-9 stations per minute. We are working on
extracting numbers of spots of each WRTC station during the period, and
hope to have these later today.
In the meantime, I want to remind contesters that the RBN's Spot
analysis Tool is now available for beta test at
<http://reversebeacon.net/analysis>. The new Tool, written by Nick
Sinanis, F5VIH/SV3SJ, is intended to provide easily usable comparisons
between multiple stations over an entire day at a glance. You can
select a date and a Reverse Beacon station on any continent, then enter
the callsign of a station, and in seconds all the spots of that station
made by that Reverse Beacon are displayed graphically, with either
Signal to Noise Ratio SNR) or frequency on the vertical axis, and the
24-hour time on the horizontal. Add another callsign, and spots of that
station are superimposed on the first. Click the "i" icon at the upper
right of the page for step-by-step instructions, if you need them.
If you select SNR, you will immediately be able to see which station
opened the band to the area represented by the Reverse Beacon, which had
the better signal during the middle of the opening, and which fared
better in the waning hours. Select a time period and zoom in to get a
close look at comparative signal strength. Selecting frequency to plot
will show whether stations changed run frequencies often and which
frequencies they were (or were not) able to hold, and when.
A few cautionary notes. This *is* an automated system. It only spots
stations that it believes are CQing. The SNR for a given spot can be
heavily influenced by QRM or QRN, so general trends are a lot more
instructive than individual spots. If Slim decides to sign somebody
else's call, and it's heard, it will be spotted, and the frequency
calibration may vary (though we're working on that) depending on the
Reverse Beacon's individual setup.
As we said, this is a beta test version. There are a few limitations
right now - most important, it does not yet work with Internet Explorer,
so you will need to use Firefox or Chrome to test it. While Nick is
working on that problem, we'd like to get comments about the usability
of the tool, reports on any bugs you encounter, and any other input you
want to provide. While we're not averse to comments on CQ-Contest, you
can avoid a glut there by sending your comments to us at
skimmer@dxwatch.com.
We look forward to hearing from you!
