the problem is that when I turn on the device a loud plop is heard on the speaker and in the electronic scheme I do not find what is the component or components that makes that plop so loud, I do not know if it is on the main board board or in the PLL board, otherwise everything works perfectly also a small plop is heard when changing the band and when changing AM and FM modes, in SSB and CW does not occur, also when transmitting when you press the microphone to transmit hey that annoying plop on the speaker ... I can't figure out which component is missing.
