Thank you all for your replies. I will only be using the 610 to monitor my transmit waveform in sideband and AM. I just wasn't sure how the 610 could be used to monitor receive IF. At this point, I don't think I'll bother with that function for now. Anyway, I was able to get a restored SB-610 from eBay for a fair price. As for a spectrum scope, I'm still waiting to see if Elecraft will release a stand alone unit.
