Marutsu Denpa is relatively new parts shop chain located in Japanese major cities. They focus on amateur radio item as well as other computer item just like Radio Shack in good old days. Recently they released an original direct conversion receiver kit MRX-7D-FK. In previous blog topic, we reported that they had a seminar course to build the DC-RX. The kit price 12,800JPY is expensive for those who experienced QRP club kits. But for newbies who never experienced kit building and DC-RX nature, this kit will be a very good educational material proofed by Marutsu corporation. We can observe they are using two 8-pin dip ICs. They are supposed to employ NE612 and LM386.
