Along the past few days, I have published on my blog several examples of what could be done with the enormous data that is available from the WSPR database.
Among the examples: Receiving antenna evaluation, Station performance evaluation, comparison of 2 transmitting antennas, comparisons betwen VOACAP predicted SNR's and real reports, etc...
It may give you ideas... In the mean time, I would appreciate your comments, suggestions and ideas...
The data is available to everybody: a gold mine !

The Drift value given in WSPR can be useful yet needs some understanding to interpret. Until recently I personally paid only passing regard to the figure.

An interesting thing is that the only station that does not see drifting banana like signals on the waterfall is the person producing them.

Following recent discussions on Knights QRSS. I think we can come to a few conclusions. The decoded value is the result of drift from the TX station and the Rx station. If the two stations drift in opposite directions the figure will cancel and severe drift could be masked.

I have now started WSPRing on SIX

DIAL 50.293,000
Tx: 50.294,535

This, of cause, only have value if a critical mass of active stations is reached, so please join in if you are at all interested in VHF propagation.

Currently running 32dBm to an omnidirectional, vertically polarized, antenna.

I plan to run this activity throughout the day and evening time until the end of summer ES (unless, of cause, if it's a complete bust with no activity) When not otherwise active on the band.

This seems a handy place to Notify and Remind everyone about my 5 unit Multimode Visual + WSPR MEPT.

Reports to the WSPR Spots or Screen Captures are always welcome, whilst it does involve a shift of Dial Frequency to 10.1386 in order to receive the Beacon, during this time stations can still RX and TX in the 10.140100 to 10.140200 Range.

MEPT Frequency 10.140073MHz.
Power 40mW.
Antenna 40m 1/2 Wave Doublet + ATU - OR 6m Vertical + ATU - OR 0.9m Hairspray Vertical. (Variable)
