6 thoughts on " Ron reminds us that MFJ still offers a shortwave radio kit " Dave M February 9, 2022 at 9:04 am. The MFJ-8100 is a very nice regen; I own an Ocean Hopper, Span Master, Space Spanner, Explor-Air, GR-81, and TenTec 1253, and the 8100 simply works best.

They work best when the antenna is at least a quarter wavelength at the lowest operating frequency, 65' for 80m, for instance. To maximize the effectiveness, and have something useful down the line, you could build a small tuner. An L-network random wire tuner is probably the simplest matching network in existence, designs about on the net.Second, insert the wooden bolts. After calculating the measurements of your antenna, it's time to take action. One inch away from another, insert 2 wooden bolts into a piece of wood before threading the one tip of each cord around a wooden bolt.
