PSKreporter Spotter Stats

I’ve participated in contributing real-time FT8, FT4, JS8, WSPR & CW spots from 630m-6m since about 2018 using several different simultaneous multi-band, multi-mode SDR spotting systems.  These have been built on various SDR hardware including the Redpitaya, KiwiSDR, RaspSDR and more recently RX-888.  SDR software has included CW Skimmer + CWSL + CWSL_Digi, DigiSkimmer, SparkSDR and most recently UberSDR.  All of these systems are capable of uploading spot (date/time, call, band, mode, SNR and grid) information to the PSKreporter server for mapping.  Behind the scenes though there is a statistics page that ranks top spotters by raw number of decodes overall as well as per band, though I’ve never cared to the interface nor the method of crediting spotters.

I’ve also used and contributed WSPR spots to the WSPRnet.org system which is in turn used by wspr.rocks which itself has a very nice user interface for competing in daily spot reception challenges.  With that interface in mind I’ve come up with my own PSKreporter display I’d like to share.  Its still in its early stages, but the idea is to provide a PSKreporter Top 50 Spotter Ranking view that more easily visualizes the spotter data much like the wspr.rocks challenge and credits spotters accordingly.   You can read about the math behind the rankings if you’re interested.

UberSDR @ K1RA / KW4VA

I’ve been playing with KA9Q-Radio SDR software over the past year, which runs on Linux and supports the wideband RX-888 mkii SDR hardware.  Recently M9PSY wrote a phenomenal system around that software titled UberSDR.  This is both a phenomenal web based SDR receiver, capable of supporting unlimited users and unlimited bandwidth coverage / listening between 0-30 MHz.  It is open-source and can be easily downloaded onto a Linux OS with a one line script which creates two Docker containers. Check out my K1RA UberSDR instance here and a list of other running the software publicly available UberSDR instances.  There are numberous features above and beyond a typical web accessible SDR, like real-time digital mode decoding and mapping, live and historic band condition graphs and local noise floor monitoring and graphing per band.  Check it out!

VaQP APRS Tracker for 2025

The 2025 VaQP APRS Tracker will be available again this year and is now live!  For the map view and text table view useful for home users to watch and track stations see:

https://k1ra.us/vaqp-aprs/

This system is in support of tracking radio stations in motion over the March 15-16 weekend and participating in the Virginia QSO Party 2025.

The tabular, text view of VaQP station callsigns contains their 3 letter county or independent city (C&IC), their time spent in the C&IC (C&IC AGE) and the age (minutes) of their most recent GPS beacon spot (SPOT AGE).

Stations in a new C&IC less for less than 30 minutes are displayed in bold italic. Stations are sorted newest to oldest by their last GPS beacon time. Lines are color coded green, yellow, pink and red for ages  <1, <2, <3 and 3> hours according to the age of the GPS beacon message.  Calls are aged out if they haven’t generated a beacon in more than 4 hours.

The map functions the same as prior years. Click on a color county or city (C&IC) for its name and 3-letter designator.  Click on a colored circle (green, yellow, orange, red) to zoom and expand a closely grouped set of APRS stations to reveal their individual callsigns.  Use the buttons on the left of the map to focus on a certain area of Virginia (N, SE, C, SW).

For mobiles or smartphone users looking for just the VaQP tracker textual station data, check out the VaQP Mini Tracker URL here:

https://k1ra.us/vaqp-aprs-mini/

In motion station wishing to participate and using an Android phone, grab APRSDroid, free and tested from https://aprsdroid.org/download/ or Play Store (for pay). Any other APRS-IS compatible Android apps should work too.

iPhone users must purchase the APRS TX IOS app, which seems to be the least expensive app and supports APRS-IS.  NOTE APRS.FI app does NOT work directly with the APRS-IS network so it will not work with my VaQP APRS Tracker system.

ALL app users be sure to get your APRS pass code at https://apps.magicbug.co.uk/passcode/ by entering just your call sign and retrieving the 4-5 digit code.  Enter the code into the smart phone APRS app so your location is sent through the APRS-IS network for my server to detect and plot your location.

VERY IMPORTANT: There is no need to register your call with me as long as you follow the info about adding VQP or VAQP in your Beacon/Text message.  Add the word VQP or VAQP (case insensitive) text anywhere into your periodic APRS Preferences “Beacon message” or “Comment field” broadcast text. My app will automatically add and start tracking your location and display it on the map and in the table view.

Please email k1ra@k1ra.us with your VaQP plans for using APRS, for example what CALLSIGN-n you’ll be using in case you can’t set up your Beacon so I can manually add you to the spotting list.

Email any comments, questions or suggestions to k1ra@k1ra.us

K1RA SDR online

As of June 2022 all K1RA SDRs were offline due to wind and tree damage after a storm that brought 80 mph straight line winds through my Warrenton, VA QTH.  All my wire antennas were destroyed. See news article about other damage in town.  I’ve managed to get something temporary running using a 50′ random wire.  Check out latest info.

My KiwiSDRs are back on the air! Back during early 2016 I invested in a Kickstater project called KiwiSDR. This project was the development of an add-on cape to a small form factor, Linux computer known and the Beaglebone Black. This hardware allows for up to 4 simultaneous online users to tune in any part of the HF radio spectrum from 0-30 MHz, using several different modes, as well as providing visual feedback of signals and some demodulation of digital modes. The software employed in known as OpenWebRX and was originally written by HA7LIM (now maintained by Jakob DD5JFK here), but was modified by KiwiSDR founder KF6VO to support some specific features of the new hardware. If there is an available slot on my SDR, located in Warrenton, VA grid FM18cr, you may tune in and listen for yourself by clicking on this link or picture below. If it is full you may try one of the many other KiwiSDR’s found listed at the KiwiSDR Receiver List. There is also an OpenWebRX Receiver List.
