Dave, You don't have to build that mixer to shift the ham band down to the audio range, a Softrock receiver will do that. For that matter, you don't need the I and Q channels, so any DC receiver without audio filtering after the mixer will do that job too. Turning it back into RF is the bigger problem. You need an SSB generator followed by a wide band filter for that unless you want to tolerate the carrier and the opposite sideband as well.
