Many small tuning ranges (37.9 kHz at 10 kHz and 61.7 kHz at 30 MHz) can be tuned by the 10 turn potmeter. Press the up/down switches to go to the nearest next small tuning range. For large frequency changes, set S1 to coarse tuning. Otherwise you have to press the up switch 1000 times to go from 10 kHz to 30 MHz!!

It's a simple L match using a single variable capacitor and coil. For the coil I wound ~100 turns of 26 Ga wire on a one inch diameter wooden dowel. The wire size can be whatever you have on hand. I twisted a tap every 10 turns. I drilled a hole in each end and glued in a machine screw to mount the coil to the bottom of the enclosure.DIY make Short-wave antenna. please Click here to get our dipole antenna. The antenna as long as five meters of glass fiber reinforced plastic rod 4-5, 50 m cable, you can easily self-control, Ham is the preferred antenna space is limited, we ask everyone to do the right hands. Made with the design drawings: Inch size is, we convert it yourself. 468 divided by 5.90 = 79' 3". The number 468 divided by the frequency above is the formula for calculating a half wave antenna length used all the time by Amateur radio operators in building many different kinds of antennas. You'll need about 435 feet of wire for this antenna plus appropriate length of coaxial cable. Setting up the 1886 loop is super easy. First, attach a length of coax to bottom of the amplifier box. (The 1886 uses SO-239 connectors.) Attach that coax to the top of the Bias Tee. The Bias Tee supplies power to the amplifier mounted on the loop using the coax and without introducing noise. Run another piece of coax from the bottom of the ...Shortwave Radio Balun DIY KIT for Ham Radio 1-30MHz NXO-100 Magnetic Balance. Opens in a new window or tab.
