HF Transceiver in my shack ..!!!

       Hombrewing a transceiver without kit is a real adventure. Learned lot of things by brewing this transceiver and tuning it without a receiver was challenging. Its BITX design i followed and VFO is DDS based. Got few contacts by first power up. Output power is not measured accurately and i believe its not more that 8 Watts. By the way i like to operate on QRP mode to save some power as well as to learn capability of qrp mode.
