Really good news. We are cooking along with WSPR on 60m.

Last night we got 9 spots in one transmission at distances of over 9000km (second last col)

Great news on Friday night we had a record number of spots on WSPR. At one stage we received 8 spots in one transmission, quite a feat on its own! However not to be out-done we broke another record last night. Werner DF6MK, last night, got 14 spots with successful decodes in a row. This is quite an important achievement as it demonstrates the consistency of the signal. I don't mean that the signal is specifically good, just that what ever the signal quality is, it is consistent.


Record = 8 spots in one tranmission
Record = 14 Decodes in a row from one station in Europe

Here is the latest image from 18:32 (GMT) last night from Werner DF6MK

Hi Stewart,

Here comes a picture from the 18.32 UTC spot.

Notice the funny line at +-40Hz (circled in yellow), that's us!

Hey Werner,

Thanks for that image. Due to drift on the radio we are actually transmitting at 5.250034Mhz which is 10Hz down from the QRM on 5.250045Mhz

Our setup in WSPR says we are running 5.250045Mhz but as I said due to calibrations issues we are 10Hz lower which puts us in the clear part of that channel.

Please let me know if you still think we should QSY ??

Hi Stewart, hi all!
Before condx open the band, a screenshot from the 5.250045.
As you can see, there is a line like a carrier exactly on ...045 MHz. 50 or 55 seems to be much better. But lets test the frequency some days, before youtry a change.

The beacon seems to running nicely so far. Lets cross fingers.

Here is the list of unique spots last night (The second last col is the distance in km)

Hi Stewart,

thanks for the info.
I think we will have a lot of spots in the future on the 5.25 MHz allocation.
We don't have frequencies near 5 MHz in Germany, so I have to listen only.
My location is favoring all south paths, the hill is sloping to the south at an angle of nearly 20°.
This afternoon and evening I'm in a local sked and have to transmit. My Perseus doesn't like to much HF at the antenna input ;-), therefore I will start listening abt 19.00 UTC.

Werner, DF6MK
