Hi Klaus and group He doesn't seem to have taken MF on board as far as I can see. May one of his rigs can be modified I have not checked my self. He does mention the use of Si570 programable xtal. I have one on a board with set frequencies from a PIC and selected by binary from a dil switch. They will not operate as low as 500kc/s so they have to be divided with either a CD4040 or CD4060 or any other logic divider. However it gives stable selectable xtal frequencies. In this case it is probably worth going the extra mile and make up a DSS as the master oscillator which will give VFO coverage. I think your pays your money and takes you choice as they say.......
hee. Cheers Klaus. 73 es GL Pete M0FMT IO91UX
