In this article, the current consumption for a selection of popular HF transceiver was examined to determine, via an on the field comparison, whether they were right for portable operation. The radios evaluated include the Yaesu FT-857D, Kenwood TS-590SG, Icom IC-7100, and Kenwood TS-480SAT. The measurements were taken beginning frok 5W in 5W increments up to 100W. The results showed that the Kenwood TS-590SG had the highest current use while the Yaesu FT-857D had the lowest. The current consumption of all radios increased as the power output increased.

Detailing a Yaesu FT-857 and ATAS-120 installation in a 1997 Toyota Tacoma, the author used Polar Plot to map signal strength. Using a hand truck with a laptop, FT-817, and an Iron Horse antenna, they circled a chalk-outlined 100-foot diameter, revealing potential nulls towards the truck's rear and through the cab, offering insights into antenna performance.

After owning the second-hand radio for a few months, it developed a sense wire failure, limiting output to 20 watts. Yaesu support advised the owner, an Electrical Engineer, to investigate. The issue was traced to a blown digital transistor, Q1032. Yaesu provided free replacements, revealing intricate internal components during the repair.
