SOTA Spot Monitor Software
Free Download Below)

SOTA Spot Monitor is similar to a DX Cluster client program but is dedicated to spots of Summits On The Air (SOTA) stations. It can check for new spots at a high rate (every few seconds) but completely avoids placing any additional loading on the SOTA servers by retrieving spots from the SOTAwatch feed on Twitter.com.


Features include configurable filters and audio alerts. Filters can operate based on summit/region/association/country, activator call, band, mode, points or spotter call. The filters can be applied to the audio alerts, the spot list display, or both. For example, the filter example below is used by an operator in North America to limit the audio alerts to the first spot of U.S. and Canadian summits worth 6 points or more, operating CW on 20, 17, 15, 12 or 10 meters, and spotted by an American or Canadian station:

Custom audio alerts for particular summits, regions, associations, countries or activators can also be created. For example, if an audio file containing goat bleats exists and is named WG0AT.wav, it will only be played for spots of that station. An audio file named G-CE.wav would be played for any spots of summits in Central England, while F.wav would be played for spots of any French summits.  

The spot logging capabilities allow all spots or just filtered spots to be logged simultaneously to two different files in two different formats. This feature is especially handy for activators who wish to keep a record of all their spots for viewing or analysis later.

The spot listing includes useful drill-down capabilities. Double-clicking a summit reference opens the summit info page at Sotawatch.org, while double-clicking a callsign (station, spotter or even in the comments) opens the owner's page at QRZ.com. If you work an activator and want to log the chaser contact, the Information tab provides you with easy one-click access to the Submit Chaser Entry page at sotadata.org.


SOTA Spot Monitor has been tested on Windows 7, Windows Server 2003 and Windows XP.  It likely works on other 32-bit and 64-bit versions of MS Windows as well.

(Unzip, run Setup.exe, follow prompts)

IMPORTANT:  When installing the software, either accept the default destination directory of C:\SOTASpotMonitor or specify a different destination directory *OUTSIDE OF* the Windows Program Files tree (or similar variant for your operating system). The software may not function properly if you install it inside the Program Files tree.

NOTE: If you are upgrading from SOTA Spot Monitor v1 (any minor version) then you must download the full setup package above and run the Setup.exe program, just as if you were installing it for the first time.

Revision History

-- v2.03 --
1) Major changes including inclusion of spots directly from RBN, RBNGate gateway, ability to read SOTAWatch spots via RSS from SOTAWatch instead of via Twitter, etc. Many of these capabilities are hidden or disabled, and are only enabled when the software runs as RBNGate.

2) Retrieving spots from the Twitter API (the method used in all prior versions) is no longer an option since Twitter is now periodically sending this text instead of spots: "The Twitter REST API v1 will soon stop functioning." All spots are now retrieved via the RSS feed at Sotawatch.org.

3) Summit Name, Points and Operator will no longer be visible in the spot listing since these values are not currently provided in Sotawatch's RSS feed. The columns have been left in place for now (removing them would take substantial effort and I'm trying to get a post-Twitter working version of the software released ASAP).

-- v1.06 -- 
1) Modified the parser to handle the breaking change that Twitter made to its query API's output data format.

-- v1.05 -- 
1) The spot's comment was being omitted for spots received from an SMS gateway. Now this problem does not occur.
2) Log files using a delimited format were omitting the callsign of the spotted station. The spotted station's callsign is now included.

-- v1.04 -- 
   1) When callsigns were spotted both with and without a "/P" designator, an alert was
       being generated each time. Now an alert is only generated once.

-- v1.03--
1) Added a horizontal scroll bar to the spot list.
2) Various minor changes to improve parsing and display of oddly formatted spots.

-- v1.02 -- 
1) Fixed an issue with the frequencies being incorrectly rounded from what was spotted. Additional improvements were made regarding frequency formatting. Thanks to Gene KC3RT for reporting the bug.
2) Other minor improvements.

-- v1.01 -- 
1) Fixed an issue with the setup package that would not allow the software to install on Windows XP. Thanks to Rob W7GH for providing the solution.
2) Fixed the character decoding so that HTML character codes such as ";amp;" will translate properly. This also corrects an issue with the "/" sometimes displaying as "\/"
