An amateur radio repeater is an electronic device that receives a weak or low-level amateur radio signal and retransmits it at a higher level or higher power, so that the signal can cover longer distances without degradation.

Many repeaters are located on hilltops or on tall buildings as the higher location increases their coverage area, sometimes referred to as the radio horizon, or “footprint”. Amateur radio repeaters are similar in concept to those used by public safety entities (police, fire department, etc.), businesses, government, military, and more. Amateur radio repeaters may even use commercially packaged repeater systems that have been adjusted to operate within amateur radio frequency bands, but more often amateur repeaters are assembled from receivers, transmitters, controllers, power supplies, antennas, and other components, from various sources.

Interested in learning about repeaters in the Laredo area, you can always look up to the elmers such as Bob Roszkowski W5EVH who has vast amounts of experience in the field.  Everything from building, modifying and tinkering with RF linking systems.  Bob was instrumental in many of the repeaters in the Laredo area, along with the design and infrastructure of the South Texas Link System.  Learn about IRLP and how the Allstar network works!

The W5EVH repeaters, 147.120, 146.94 are both Bob’s designs.  Check them out!

There are other type of repeater systems in the Laredo area such as the KE5WFB repeaters.  Aaron Elekes N5VAE who enjoys the Digital age of technology has the APCO P25 (Project 25) VHF repeater 147.360 and the DMR/P25/Fusion & D-Star 440.600 systems.  Both have different type of modulation modes and are on separate linked networks.







Art Hase AE5JH and Frank Aguilar N5SSH both have the new Yaesu Fusion repeaters.  This is similar to the digital D-Star/P25 and DMR modes.
