Midland Alan 8001

[Manu]

Hello, I am trying to repair an alan 8001 of the old ones, it has a problem, the modulation is very low, after changing the b754 and a473, apart from the 2sc2312, which had a leak, the device remains the same, I have observed, that with hardly any power, about 100mw if there is a good modulation, but when it goes up, it disappears, ic4 seems correct, I have also checked the part associated with the b754, everything seems to be working fine. It is as if the modulation is saturated when there is some power. greetings and thanks

Build RF probe and check where power disappear.

Hola de nuevo, el problema no es la potencia, pero la modulación con 100mW es buena, pero con 0.5w o menos, desaparece, teniendo que hablar fuerte o poner un micrófono moldeado para tener una modulación media.
