I built one of these preamps way back when Diz first began offering them. It
works great! I also purchased several spare 2N5109 as he had the best price.
Again, good transistors.
I tested the K ‘n P model preamp which I had built for a friend against a W7IUV
which I had built some years before ‘dead bug” style for myself and both showed
about the same gain and low noise. I still run W7IUV preamps on my K9AY loops
as well as some other RX antennas though have been thinking about changing one
out for a Norton type.
