Antenna may be made practically from any wire (strand, solid) having a reasonable diameter 0.5 2.0 mm (24- 12 AWG). Antenna may be installed at any balcony of 3 to 6 meter length.
There are quite a few variants of the design accompanied with many opinions on the effectiveness of the antenna. This page features links to some similar projects and a homebrewed personalized version of this portable antenna tuner
This project is a full wavelength, horizontal, loop antenna for the 40 metre Amateur Radio band, built using insulated copper wire in a diamond shape, supported by egg insulators, tethered to 4 masts, each 6.5m high
Just a simple signal generator based on ADF4351 module from fleebay allows you to generate one single frequency that can go up or down in 100Khz steps via two push buttons.
The table above represents a rough approximation of radio propagation conditions on 160 meters. It is based upon selected high-latitude magnetic observatory data which is used to estimate the influence of the auroral oval on 160 meter path propagation
Common-mode chokes are useful solutions for RFI reduction. Winding a few turns of coaxial cable on the FT 240-31 toroid can reduced the noise below the received noise floor. In this article author measure different chokes
Serial CAT interface to control a Yaesu FT-817 transceiver. Inspired in the James Buck (VE3BUX) FT-857D library and crafted to Andy Webster FT-817_Buddy project, but usable by anyone to control a FT-817 radio.
