My Multimode + WSPR MEPT is back on 10.140073MHz from approx 15.00 GMT today 12 May 2008.

Further developments are afoot these will affect the 'other' visual modes.

This is an interesting bit of activity, and has really captured my interest. I have played with both PropnetPSK and with the "self-reporting" feature in the digital interface within Ham Radio Deluxe, but find this the most intriguing, particulary for low power propagation reports.

I am 47 years old, and currently living near Oxford, England, working for the U.S. Embassy here in London. My home call is K2PI. I have also held the calls ON9CPI, LZ/K2PI, XUF2B, XU2FB, HS0ZCI and KE2FB/DU3, among a few.

I have been asked how do I make the spot plots, which appear on http//f6irf.blogspot.com/
Below are a few tips (probably there are other ways to do it - so it is just one method):
1- Filter the data of interest (by band/callsigns/etc) from the spots page and copy it (ctrl-A, ctrl-C)
2- Open Wordpad and "paste special", "Unformated text", then "save as" .txt
3- Open the txt file with excel using "space" as separator
Now the rest is just Excel data manipulation - the purpose is not to give you an excel course or to rewrite the best seller "excel for the dummies", but just a few tips

Some statistics from the meptspots database downloadable from the wsprnet website (update 0735z 8-May-2008). There are 402 reporters and the top ones are VE1VDM (with 27969 reports) followed by K1JT (24892) and W1BW (23269), while the most heard stations (1863 as total) are K1JT (27047 reports), VE1VDM (23709) and WB3ANQ (22160) [IV3GTH, I2KBD and IK1RKU among the italians]. The longest distance WSPR report is PA3ABK heard by ZL1ANY with 11937 miles (not counting the strange callsign/grids reported which seem wrong decodes). F1VS and F8RZ heard by ZL1BPU (11831 and 11811 miles).

As already mentionned,the current WSPR recommended frequency is far from being ideal for WSPR users located in Europe.
A certain number of Region 1 countries still has 7.100 as upper band limit, therefore 7076 is in the middle of the SSB segment, which makes the frequency unusable (at least on RX), especialy in the evening and early morning (when the SSB activity is maximal and the conditions still favorable for continental distances). This almost forbid the band to be used for tests with AS and OC both at short path (EU-evening) and at long path (EU-morning).

The Multimode + WSPR MEPT on 10.140073 will be off for several days from later today 03.May.2008. Being a Manned Beacon, under the licence conditions I cannot leave my Son or XYL in charge.

Google Prop Map on WSPR net provides an idea who is or has been reporting, in particular when one is using the magnification feature of
the Prop Map.

Of course reporting is by no means the same as receiving!

This indicates another reason for a positive indication of who is in the
receive mode and is participating as a reporting station.

Checking in and out to some sort of list or roster would help here.

When starting up WSPR, the program could send a signal to a central
point:
Station is in receive mode AND download mode for frequency
XXX.

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)
