FT-DX5000MP - antenna tuner repair
After 2 years without any problems i had problem to tune my antenna on all bands. I identified the problem in automatic antenna tuner. The final decision was fault ceramic capacitor 18pF / 3kV. From datasheet I saw, that the manufacturer TDK produce also 6kV series and I changed all possible capacitors in antenna tuner 6kV instead of 3kV.
Bad capacitor 3kV and new one 6kV
