I've posted an update on my end-fed Zepp project at www.garage-shoppe.com. If you've been reading that series of posts, you know that my first attempt was successful, but a little rough around the edges. In the past week, I've built a much more refined, QRP version using a 200-Volt trimmer cap in a nice, small package. Yesterday I gave it a quick test, suspended between a tree and my front porch. Within 5 minutes of turning on my FT-817, I worked YU1DW on 20-meter SSB, 2.5 Watts output.
