WSPR balloons enthusiast forum!

Hi dear friends over the world!
This is Roberto, 42 years aerospace engineer from southern Italy, amateur radio operator with callsign IZ7VHF.

I'm posting this topic in order to notify to all balloons launch enthusiasts that there is a forum with a lot of informations about this matter.
Expecially, on the forum there are materials to build balloons with WSPR transmitter, based on firmware made by Hans Summers on QRP-Labs.

The forum is on website http://www.radio-signals.com

You can be part of discussions and ask anything to clarify your doubts.
Thank you very much indeed and I wish you all the best!

Sincerely,
Roberto.
