LA3JJ's blog

Hi all wsprions,
You may find photos of the my latest project here:
https://groups.yahoo.com/neo/groups/redpitaya/photos/photostream

and there is also a manual in the files section of that group.

I will soon make a corrected version of the PCB and put it for sharing on OSH Park.

Se also attached documents. (The footprint is largely the same as the RP Zero, a Zero is hiding underneath one of the units)

Happy wspring!

The Softrocks, and many other Si570 based designs are a bit temperature dependent.
I am trying to tx on 10140277 Hz with my portable rig. To check the frequency I will just read the frequency reported back to me..
As you all know the result is not very clear. One stn will tell I am on 289 Hz and another is telling me I am on 258 Hz.
I am all alone in the woods with my little softrock and on frequency unknown!

What I have done to resolve this may be of help to some of my dear wspring friends as well, so that is why this is written.

Hi all wspr friends,
There are moments, - also in our wspr life that should be shared.
A screenshot may say a lot more than words can express. ;-)
Instead of posting the links on the chat I will put them here on this blog with a short comment.

Was not able to upload manually so some of the files are included here as attachment:

For some reason I have never been able to run multiple wspr programs, but now it works. Using WinXP and internal + usb soundcards. Passed 24 hrs test now. See the attached screen pictures.

I will be back again now from 5 to 26 of March. 30m, 17m and possibly 12m.
location is IL38ar Fuerteventura northwest.

I'm back home and things are back to normal.
Sorry if some of my "unnormal" experiments with the WSPR and the WSJT7 did upset somebody.
Being without internet made me try to communicate directly in WSPR mode, probably not a sin, but still not normal behaviour!
I will not make it a habit.

Two problems that I would like to mention:

1. When using WSPR only p/ calls like EA8/LA3JJ will not work.
Solution A: To use the home call and in addition send complete CW ID.
First days I used MixW and WSPR simultaneously, sending CW ID from MixW at higest rate in the last seconds of each timeslot.
This was a procedure that required manual timing so I looked for other means.

Solution B: To use WSPR and WSJT7 simultaneously sending DE EA8/LA3JJ in some of the WSPR Rx slots.
This required less timing effort and as an extra bonus WSJT7 does have a built in CW ID generator (at 800Hz).
I also tried using WSJT7 as a Tx robot sending all the required WSPR information which worked fine except from uploading of received messages.

Dear friends - men and robots,

The development of our hobby is amazing, some new things will catch on very fast.
I was thrown into this WSPR thing late November last year and must admit that I have not had many “real QSO’s” since then. And my wife also appreciates this as I can in a greater extent be a part of the real world while I am enjoying my hobby. She noticed the change, so I explained some of the changes. “Oh, so you are just talking to robots now, well that’s a strange development!”
It made me think, would be better to know if there is actually a person somewhere in the other end.
May be WSPR QSO mode is something for me
Tried it for some days now and it is not easy. Only correct answer to my CQ EA8/LA3JJ call was from VE9DX and it was hash coded as it should be. But conds changed and I took to long…
It seems that everybody else are in the same learning curve as myself.
To you all: read the manuals carefully and understand about hash coding and limitations of messages before you go on. I have learned a lot through trial and error the last days and hope I will soon be able to make WSPR QSO’s efficiently.

I will be operating from my QTH on the island of Fuerteventura from January 13 - January 25.
