I'm not at Dayton this year, but Jeff W8CQ of Harbach Electronics is still selling SP-2 kits there. Jeff currently has my remaining inventory of twelve SP-2 kits. However, I've got components to make additional kits, except for the SP-2 front panels. My panels have been made for me by Ten-Tec's custom enclosure division, but the company is soon phasing out its custom enclosures. I've asked for a quote on having additional front panels made before this happens, however, and if the cost is acceptable I'll order another 50-75 panels. I don't know pricing yet on the SP-2s but I'm sure the kits will go up a bit. By the way, if I do order additional front panels, they'll be identical to the original front panels, except powder-coated black with white lettering. I think they'll look good, but obviously won't be as classy (or as expensive) as the black anodized, engraved panels I made up last year.
Two other items: I discontinued my SP-1 kits a few months ago, but then just a week ago my XYL found a batch of SP-1 components buried under some boxes in our storage building. These aren't assembled into kits, but everything is there, so if you'd like an SP-1, just email me directly and I'll put one together for you. Price is the same as the closout price ($120 plus $12 shipping).
Also, I have now restocked all my SP-2 front panel circuit boards (but not the front panels themselves) and also the microcontrller PCBs. A few folks have wanted to replace damaged boards in their SP-2s, so replacements are now available for these and all the other PCBs as well. Again, pse email me directly if you're interested.
Tnx and 73,
