Above is a new QRP transceiver that uses a modified receiver board (single band receiver) and ssb board from the SDR transmitter. Receiver has been modified by substituting a different AD9850 DDS and external crystal filters instead of the adjustable crystal filter.
This is a new cw transceiver design in prototype. It outputs 5 to 10 watts depending on the supply voltage. 3"x5"x7" Now being developed as a single board project and may be available in kit or PCB soon. E-mail with any queries.
