This project is estabilished on the basis of initial modifications of FT847
by our colleagues in the Estonia - Hellar ES1II and Arvo ES1CW - mni TNX
guys! Well done.
At the moment, the original version of the modification includes more than 30
TRX across the EU and probably worldwide, which can assure that the solution is
repeatable and effective.
To achieve these results, filters should be made according to the diagrams
below:
What you will need:
1. PCB’s (
)
2. Wire CuAg 0,5mm
3. Cu wire 0,5 mm in isolation:
4. Tuned filters 7V1S:
5. The elements of the list is located at the end.
