Default Re: Roberts R200 LW reception poor

I found out that the image frequencies were caused because the LW tuning coil was tuning to the wrong frequency range. The ferrite rod had been wired up according to the schematic for a pre 8200 version. On LW band the LW and MW coils were in series causing too much inductance and wrong tuning. I rewired the switch and coils as they should be for a serial number of 8304 and the tuning improved greatly and the images disappeared. Thanks for all the help. Steve.
