In the Oct 2009 issue of CQ Ham Radio, JN1GLB, Makoto Kasahara wrote the article of ALTOIDS PA (20w amp for QRP rig in Altoids). It is the same formula with ATS-3B. The article describes that he would make the board with requested people.
The ALTOIDS PA is IRF510 parallel PA with 20w output in HF bands.

KEM-RX3.5 : KEM has been released the 80m receiver.
KEM has released the 80m band receiver (KEM-RX3.5). The receiver is superhetrodyne and IF is 455KHz. It's the same diagram that the 40m band reciever has. The KEM-RX7 for DX orders is $54.87, therefore I assume it will be the same price range.
