Hello Paul, I remember them ... well. I also remember the receivers were triple conversion ... some used a 30-31 Mc crystal... the others used a 10-11? Mc crystal. I also remember the quick calculation for amateur band service was to use the existing 3rd IF conversion crystal and divide by either 14 (30-31Mc crystal) or 42 (10-11? Mc crystal). I am about to toss the manuals for them ... Neil
