Hi all. Would any of you know where I could buy, borrow, beg for, the schematic diagrams for my RA6778C? I have a problem: the "mode" key doesn`t do anything. The rest of the receiver works fine. I`m stuck on LSB or CW. (because there are freqs. in memory in these modes. That means that the transfer from mem to cpu works ok. Anyone can help?? thanks, de Gilles, VE2AMN
