Unfinished multiband transceiver project

by OH6DC

This QRP CW rig is under construction and development, but already functional on 80m band. It is based on NorCal Sierra multiband design. Band modules are used for six HF band coverage (80-15m). Other circuit blocks are to some extent modular too, to allow easy experimentation and changes. TX output power is 2W. IF filter has four xtals (4.915MHz) and adjustable bandwidth. There is RIT function and audio derived S-meter. VFO runs at 2.9 - 3.1 MHz. The cabinet is recycled from an old cassette deck and the VFO knob is a plastic jar cap.
