Congratulations for your flight! Roberto.

Hi all I just built a tracker with Eduards fw and got it working so here is some info that I hope will help others. We need to download Arduino IDE, Im using arduino 1.8.9 and I know Eduard is using

When are you planning on launching so we can keep our ears open?

What editor do you suggest to use to edit your firmware? If you are able to create pages in wordpress, I can host your pages on radio-signals.com R

Nice work, the tracker looks very good. I can see you spent a lot of time in it's design. What protocol did you settle on for your telemetry? I can't wait to see it fly Stephen KD2NDR

Hallo dear Eduard, good morning to you and all. I change hosting provider one month ago, and the last one I have has a different "approach" to update by ftp client. It is possible I give you a

You can try, the code as I had originally submitted was large for the tiny 328 memory and might be prone to memory errors if too much is asked of it. The code should be streamlined more to improve

Steve, I am working on implementing the GPS reset routine. Basically, if the fix is lost for some amount of time/number of queries, the GPS goes into reset. Have you used the isUpdated() and age()

Hallo Eduard, bun? seara ?i multumesc mult ! I have read your email deeply and I'm happy there are several people involved in this nice hobby. I have a website, named www.radio-signals.com, (

Hallo dear friend Eduard, bun? seara! I'm Roberto Pietrafesa, IZ7VHF from southern Italy. I'm 43 years old aerospace engineer working where we build carbon fiber fuselage sections of Boeing 787

Great!! looks good :) keep us posted, about your progress. lots and lots of websdr around the world to keep track of the "real" altitude, usuly it stays around + - 300m of the first days float

Well I hadn't found much information on how much RF power was being used on the flights that I had read about which is why I set up the test circuit. Same with the multiple bands. I wasn't planning on

Yes, He used the modified version of u3s fw. Hans Summers qrp-labs is going to release a commercial version of this u3b probably sometime closer to the

Mikael, was your friend using the modified U3S firmware from QRP labs? It seems like many balloon builders use this firmware. I tried to obtain it one before, but the author is no longer releasing it

Hi Steve, I think that adding an amplifier would be overkill for this. You would be draining your batteries much quicker and adding another potential point of failure. The 10mw output has been proven

To my experience there is no need for an amplifier, even at the moste remote areas of the world Im getting a lots of spots runnig the 5351 barebone, Im using 20m band and cut the antenna to regular

I have made some changes to the code I found in this group's file download section to do some testing. I am deciding whether I would need to increase the RF output of the SI5351 to ensure its reports

I posted your updated files to the board, let us know how your test go.

I have uploaded your files to the board. Sounds good, keep us updated on your progress and test results. Good Luck

Here is yet another one, scl and sda got on the wrong pins, will have a closer look this weekend when I have got some sleep :) /Mikael
