Part 1 of this project is available HERE
I am still not sure if it will be a LF, MF, HF, VHF, UHF, or microwave beacon? Does not matter at this stage. The main object here is to get the hardware and firmware to talk to each other. I managed to connect all the modules together and did a test run. Well it is running and I could hear the signal on 144.480 Mhz but need to check the signal output on a scope for harmonics and calibration. In the meantime here is a short video of the "beacon" running on the workbench. I will try to work on the project later today to calibrate the frequency and check the wave signal output. I need to come to a decision on what band and frequency this beacon will run and if I am going to use it as a 3 in 1 beacon. I will also look at amplification and low pass filter designs. So far I am quite happy with the outcome. Updates to follow.
