TT2A works at 7.030 and 14.060. However, crystal sockets are used in the kit, offering a more flexible frequency switching. Crystals ranging from 60m – 20m can be plugged in to work without altering the tank coil. Photo by Youkits Photo by Youkits WORKING ON OTHER HF BANDS The frequency range for BAND 1 is…
The original idea (as seen above) was to implement a complete SSB modulator and demodulator with software in a ATTINY45 micro-controller chip and a AD9834 as DDS. The software samples microphone signal with ADC and then derives the amplitude and phase of the audio signal. The amplitude and phase extraction is derived from the in-phase…
This Open source project offers a solution to remote control of your Amateur radio station. Base for connecting other components and their remote control. The main advantage is low cost and adaptability (open source code). Arduino Band decoder – independent module kit Main functions: Independent hardware. Open code (by OK1CDJ) – you can modify. Arduino…
