Hello I am new to the u4b board, and I have started to setup my u4b. I have antennas soldered on and I made my tracking page. However when I go to the tracking page, there is no output from the TRACKER (default) program on the qrp labs tracking page.?

Any help will be appreciated.
Thanks

Hi Dave,
I am new to the U4B.
I have created balloon flight: Gadgetman, and it is active.
I am testing at my QTH at this point.
I have followed all the pointers mentioned:-

• Callsign in uppercase (in the Balloon Flight cfg)
• In my local WSJT-X cfg I am using a friends call sign with a different Maidenhead to my own, to receive the U4B TELE
• Because the HF antenna is just lying on the ground, no one else is picking up the TX, only my own local WSJT-X
• Uploaded a spot to fool Wspnet not to use the M6 spot they have memorized with my callsign.
• Set the TX to 20m, Chan 124

After many hours, the QRP Labs?tracking page has not seen me. Yet WSPR packets are recorded by WSPRNET.

Output my U4B tracker program:-

Anyone can give me some pointers on what I am doing wrong?

Stewart,

I only see the first packet in your log, where are your second packets? Locally you should see a second, 2-min transmission after the first one. It should be on the same frequency but the call sign will have data encoded in it. If you post that or decode it using Traquito?it may point to the issue.

Hi Stewart?
Please post the Basic program you entered into the U4B.

Hi Stewart?
It does appear that your telemetry is being transmitted on minute 8

Hi Stewart
It does appear that wsprnet thinks your call is in a M6 location?
Perhaps because your wsjtx is showing an M6 go to settings in your wsjtx and change it to an M4 nearby like an M4 of KG32 and upload some spots ..this may fool wsprnet.... you can change it back anytime after the balloon is launched but for home testing this is what I had to do change FN03 to FN04 and upload some spots....? your tx grid is showing at KG33xu?
and all M6 locators are rejected by the U4B program as the balloon does not transmit M6 locators and they are usually bad data.
Dave VE3KCL

Hi Dave,
In wsjtx I am using a friend's call sign ZR6N and I have updated his grid locator KG43 to just 4 chars
I find that if I use my call sign in wstjx, it does not report to WSPRNET.

So now I think I am getting valid spots in the last few hours:-

Yet still nothing seen on?

My config:-


My program:-

Hi Dave,
I have it working.
I renamed the flight and changed the call sign to ZS6STN (my ARC).
I think it was related to using the same call sign and maidenheads.

Hi Stewart?
Glad you have it working . Your basic looks like it should work fine ...mostly there to let you know on the terminal how the U4B is doing.
You may consider joining the balloon group at?/g/picoballoon/topics
They can usually answer pico balloon questions more readily
