Originally licensed in 1978, I have been interested in radio since I was very young. For many years, I worked with high-power broadcast transmission systems.
Interests: QRP, CW, VHF, Microwaves
Organizations: ARRL, CWops #878, NAQCC #3974, FISTS #14678
The current Home station:
Elecraft K3, SPE Expert 1K-FA amplifier.
VHF: Elecraft K3 for 6m, Kenwood TR-751A with RF Concepts 150W amp for 2m, Kenwood TR-851 for 432 MHz. Homebrew W1GHZ-design transverter for 902 MHz.
VHF: M2 6m5 for 6 meters, M2 2m9 for 2 meters, 12-element JayBeam for 432, loop yagi for 902 MHz on 12m tall Rohn 25G tower.
RX: K9AY Loop system
My HF tower. Force12 XR-5 and Delta 230/240.
My VHF tower. M2 6M5, 2M9, 12-element 432 JayBeam.
Yaesu FT-857 with "little tarheel" screwdriver antenna
I built my K9AY receiving loop system using a wood pole in my back yard. I used PC boards from Far Circuits to construct the switching matrix and the filter/preamp.
The remote loop select and termination select relay box.
The selector box during construction. This also contains a preamp with bandpass filter.
Completed selector box.
Remote loop select/termination select relays mounted at the loop base.
The completed loop array. It is built around an 8m tall wood pole.
The performance of this loop is outstanding. I can now hear many stations that I could never hear before. Were I to build another one, I'd probably purchase the switching matrix from Array Solutions. It doesn't cost much more than the parts to build it, and it saves lots of time.
