To get the telemetry signal on the air an antenna is needed. By necessity, the antenna must be light weight and simple. The size of an antenna is determined by the frequency we need the antenna to work at. The lower the frequency, the larger the antenna will be (There are exceptions to this rule […]
Now that I have a list of protocols and a general plan to transmit telemetry on the 20 meter Ham bands, how do I get “on the air”? This post will describe the transmitter hardware for the telemetry system. Generating Radio Frequency – There is a board for that. After a lot of searching an […]
What’s the frequency Kenneth? The big unknown for me, at least at the start, is how am I going to know where the balloon has traveled.
