The receiver uses a clever direct conversion design using an NE602 with some AGC applied to it. Like the RockMite, it uses some front end crystal filtering to help overcome dynamic range/overload issues, but with the limitation this is a single frequency radio, for example parked on 7.030MHz, the QRP frequency. Still, a full 5W on the QRP frequency will permit plenty of QSOs.

Looks good. Shame no VFO.
The SW40+ (now discontinued) was great, but sadly is no more.

For the price its very good!
You could always put in a couple higher freq crystals (same value) at the top end of the CW band with a variable external cap, and make yourself a super VXO to cover most of the CW portion. :-)
