NorCal NC-40A QRP cw transceiver

This is my second build of this legendary QRP transceiver. First one was made with digital oscillator. This one is with finished receiver stage, but need more set up in transmitter stage.

Original schematic was made by members of NorCal group - #qrp-tech at groups.io
I have got all information from files section of this group.

Al, N8WQ say:

"Wayne Burdick, N6KR designed the rig by himself in three days!  ...

For Winter 2017, the qrp-tech yahoo group began building and operating original or replicas of the NorCal NC-40A CW Transceiver in celebration of it’s 25th Anniversary in 2018.  Some qrp-tech members will build their rig with a manufactured pcb, and other group members will be building their rigs by using either the manhattan, muppet, or ugly style construction techniques. ..."
