Is there a reliable 24x7x365 WSPR receiving station in the US?

[Vincent Leveque]

I am analyzing WSPR signal reports on 20 meters to assess any correlation between these reports and solar activity (flares, CME events, etc).  Ideally I would use a single receiving station and review changes over time in average SNR, and distance to that receiving station

I've looked at receiving stations in WSPR data, to find ones that record frequently.  None cover the entire year and I have no assurance the data reported is of high quality.

Does anyone know of reliable well configured WSPR receiver stations that are managed to provide consistent reports throughout the year?  I'm thinking maybe a dedicated club or university station, or perhaps a very dedicated HamSci member.

Thank you

Vincent,

I am interested in WSPR data for similar reasons.  In addition to a reliable receiving station, you also need a reliable transmitter.  If the transmitter is not reliable, you are not sure if you didn't receive the signal for propagation reasons or because the transmitter was off the air.  We might have to look for a receiver in closer proximity to the transmitter to indicate that the transmitter is actually operational.

A colleague pointed me towards a University of Bath PhD thesis by Sam Lo entitled "Use of Novel Distributed Instrumentation in Ionospheric Research," 2022.  It is available on line if you search for U of Bath Theses.

I am interested in pulling space weather data and TEC and trying to correlate that to WSPR link closure.  There is plenty of data available, the big effort is pulling and formatting it then matching it with the WSPR data.

I am averaging SNR and distance between a single receiver and all the other North American transmitters.  I'm using a one-to-many approach rather than a one-to-one.  In addition to using SNR as a metric, I can also use average distance and count per time period.  A one-to-one approach couldn't do that and would only give information about a single circuit.

Of course a pairing of a reliable transmitter to a single reliable receiver would give good information about that particular circuit.

[Rob Robinett]

At https://wspr.rocks you can make high performance SQL queries of a database which contains every WSPR spot back to 2008.

There are 20+ Wsprdaemon sites in the US and Europe  which continually listen on all bands 2200-10m 24/7/365

Try looking at my KPH and KFS sites on the West Coast, WA2TP in New York, EA8BFK in the Canary Islands, and OE9GHV in Austria.  But there are many others.

We would be interested in your results.

Very good!  I will look into this.

Hi Tom,

Paul WB6CXC of Turn Island Systems offers the GPS disciplined, 8 band WSPRSONDE-8 transmitter: https://turnislandsystems.com/product/wsprsonde/

It has been in operation at several sites for over a year:  WB6CXC (2 sites CM88 and CN88), WW0WWV (in the WWVB transmit building), DP0GVN in Antarctica and VY0ERC near the magnetic North Pole.   They all transmit during every 2 minute WSPR cycle on all 80-10m bands (some on 6m) 24/7/365.

Soon HamSCI will be deploying WS-8s at 10+ sites around the US.

Vincent, Tom

Good luck in your studies. You are both right - there is so much analysis that can be done with WSPR.

While Rob is correct in listing those well-placed receiver stations that really do strive to be 24/7 all-year a nuance that is important to know, as it may affect the results of your analysis, is that, with the exception of KPH, the stations Rob lists have multiple antennas connected to separate WSPR receivers (as do others). Wsprdaemon reports the best of the individual receivers' SNR to wsprnet.org under the one callsign. Those multiple receivers at those, and other sites, bring added information, which has been, and will be again soon, in the wsprdaemon-specific tables that Rob acquires, where each site's receiver has its own designator.

If you are interested in a particular path I have found it most useful to make contact with the operators of the transmitter and receiver to obtain full details. They have invariably been so helpful and pleased to know their efforts are appreciated.

Vincent, I have a WSPR beacon on 20 that runs often. However like most active hams, I disconnect it when transmitting. Unfortunately I think a great majority of WSPR's are operated by hams who will shut down when their radio is in use. This can be seen on major contest weekends.

K6VZK in the San Diego area has been going at a high level of quality and consistency for about a year, all the same site, hardware and antenna, less a few hours of being shut down every so often due to power loss.

[ghby...@k9trv.org]

I have 3 different antennas each feeding a separate RX888 receiver, each receiving LF thru at least 10m.  two receive thru 6m.  They are K9TRV and K9TRV-2 and K9TRV-4 on wspr.rocks.

 

I endeavor to keep them operating 24/7/365, with occasional outages for inspection or maintenance (hardware or software) kept as brief as possible.

 

Another such station is N8GN, several hundred miles roughly due south of me.  Gwynn has made use of us previously for some of his studies.  My antennae, quantity of stations,  and operating practices have been considerably upgraded since going on the air just before the SEQP a few years ago (aka ‘totality in Toledo, OH’)

Hi folks,

I feel that I should point out, that at least in the case of VY0ERC, that a lack of observations is sometimes the signal you are looking for.  A high K index is likely to result in far fewer spots, although surprisingly to me,  not always.

Hi Pierre,

  I would add to that the observation that SNR is Signal / Noise, and the local environment of each station is a key factor in that denominator (Noise), such as local RFI, multipath effects from nearby buildings and landscape, etc etc.  It provides an extra challenge when analyzing SNR as a variable, and I know for example that Gwyn and Rob on this list have taken extreme care with this factor.

In our Wsprdaemon Extended Spot Database we add two measurements of the noise level to each recorded spot.  Using that, one can derive the absolute signal level of a spot.  But since most sites have not calibrated the antenna factor one can't know the absolute e-field intensity of that signal.

Hi Rob,

  Thanks - this careful additional measurement is essential but almost no one else does it, so useful to retransmit the information to the collective.
