The QTH is on 10 acres of forest about 20 miles west of Port Angeles, WA in the cool and moist northwestern US. I am a retired electronics engineer and hobbies include gardening and landscaping as
well as ham radio. My main interest in ham radio is the design and construction of vacuum tube receivers and transmitters of the 1950's era or earlier. Much of my operating is done with these
radios. The antenna is a full wave (550 ft) horizontal loop for 160 meters up 75 feet (23 meters) fed with balanced ladder line tuned by a homemade/designed balanced autotuner to operate on any
band. Activity lately has been primarily on 40 meters around 7030 KHz.

The new QRP rig is finally finished. It has replaced the little QRP-VFO rig shown in QST (Jan 2003 p83), performing essentially the same as that little rig (shown also in my shack photos) but is
much larger and more carefully built. The new rig covers 80 - 17 meters CW and has a 6V6 final instead of the 5763 used in the original. It now also includes a built in power supply and is used
along with the Ultimate Regen or SX28A receivers.
