I've been thinking about making up something like that but it would be quicker and easier just to order three of those. The LO is a bit close, wonder what the image rejection is like. I'd want to use 120kHz or lower but there's loran on the other side. Maybe a high side LO is better. Are there other suggestions for a simple rx for LF? -- Paul Nicholson --
