I built a new module for the DDS MEPT.
This time using a 27MHz Xtal, a triple tuned filter and conventional Class A amplifiers the output is 100mW.
On its first on air test signals were received by G6AVK at 179Km. The path crosses the London Luton, London Stanstead and London Heathrow air corridors so reflections were many and sometimes quite bizarre.
The use of Class A amplifiers puts up the current consumption degrading its status as true QRP, maybe I can brew tea with the wasted power.
