Welcome to my IZ7VHF projects’ page on radio-signals.com!

I have created this website section in order to collect all useful informations to expose my project to launch a traceable “festive balloon” with small transmitter payload. I have always desired to achieve this project since I was a kid, but the technology did not yet exist.

Luckly, at the end of 2013, searching for a QRP (low power transmitter) homemade device kit, I discovered Mr. Hans Summers (amateur radio callsign G0UPL) with his own QRP LABS and I was fascinated by his projects. You can directly reach the shop clicking here. Hans is producing a series of small QRP transmitter in a DIY (Do It Yourself) kits, the most famous of which is the Ultimate 3S kit. In his website, he describes himself as “… a simple enthusiast attempting to convey my love and enjoyment of radio, electronics, and computing and perhaps to inspire you to build something too“. Well done, Hans! You have fully conveyed it!

Combining the possibilities offered by Ultimate 3S transmitter to the experience of Mr. David “Dave” Beverstein (amateur radio callsign VE3KCL) from Canada, that has launched a lot of traceable balloons (click here for more info), I would like to accomplish the same goal!

Here you will found all informations you need to follow my project and, why not, to launch your traceable transmitting balloons in the future. In the above horizontal main menu you can surf around all project informations. Since there are a lot of informations to share, please be patient while I insert these. Thank you for visiting my website.

I expect to launch my first M-1 balloon within October 2016, after several tests on components.
