I've been offline for a while because of ApolloCon, but I'm back at it. My XYL, KD5SBI, has expressed a desire to do PSK31 on 2-meters FM (and I've confirmed that there is such a thing) and has indicated that she understands the need for an interface box. To that end, she suggested that I purchase the UMI SCI-6 and assemble it, for it is a kit, for her birthday, which is coming up soon.
