Dear Mr. Marcelvdg
I have checked the resistances R3 & R4 and they are O.K. The voltage at pin no 8 of ECH81 is 305V on the HF side and 102V on the LF side when the Band switch is in MW position. The set is working in MW position. When I keep the BS in SW4 then the voltage at pin no 8 of ECH81 is 105V on HF side and 65V on LF side. These voltages are when no signal applied. In the MW position though no signal is applied to the antenna terminal the ferroceptor is still connected.

Regards
P.Rajan
