High Frequency Ops: A Dedicated QRP Rig vs. Full Power in the Field


nearHigh Frequency, or HF, is the method used to communicate over long distances with no infrastructure other than you, your radio, and an antenna. HF signals travel beyond Line of Sight (LOS) where Very High Frequency (VHF) and Ultra High Frequency (UHF) quit working. For a lot of people just getting into the communications arena of preparedness or looking to upgrade their capabilities for regional networking, the most common question that comes my way is justifying the cost of equipment. Usually this revolves around two very different areas- QRP, meaning low power but generally ~5W and QRO, or ~100W rigs. Since the communications in the field is not a one-size-fits-all affair, there’s very different considerations from what an operator expects in a base station to what can be run for a long period of time out of a pack.
