These are SSB rigs sold by Midnight Design Solutions. I had not seen these before, nor the QST review. They sell for $55 which is pretty reasonable. My design would have been considerably simpler, but was DSB.
This is designed by Dave Benson K1SWL, so should be good. As an SSB phased design this is more sophisticated. Dave's design also allows you to choose an alternative frequency and offers more power. They should sell many when their supplier problems end.

UPDATE 1420z: Just ordered a 10m kit. Due May. I see the SMA parts are pre-fitted.
UPDATE 1620z: Someone asked me if I had given up on my ultra-simple DSB project. No, definitely going ahead still!
