HF or Shortwave

HF communications (high frequency), sometimes called shortwave, enables operators to connect with each other from down the road to around the world using HF propagation. see video below. HF communicatons goes back to the early days of amateur radio yet today is on the leading edge of technological development with sophisticated microchips and software.

YARA members are active HF users, with radios ranging from simple QRP low power transceivers and wire antennas to the latest SDR (software defined radio) transceivers, some with powerful amplifiers, using CW, voice, email, and the latest digital modes such as FT8 and JS8Call. They operate from their homes, mobile, and portable while backpacking and from mountain tops. See some of the equipment and pictures further down the page.

Radio Frequency Interference (RFI)Radio operators sometimes experience difficulties in HF communications because of background noise covering the desired transmissions. Sometimes this occurs from natural events like the aurora. Other times it is caused by human activity RFI from power lines and electronic devices. RFI during a power outage

Radio Nets
Some members check into various HF radio Nets which are operated though the week. Many Nets are part of emergency prepareness exercises.
