These amateur radio repeaters provide a very valuable service to many stations, and in particular those that do not have particularly good locations or those amateur radio stations that are using only low power. A repeater, whether an amateur radio repeater or even a commercial repeater is a station that receives a signal on one frequency and simultaneously re-transmits it on another. Repeaters are sited in good locations with good coverage enabling stations that can access the repeater to be heard on the output and thereby take advantage of the location of the repeater.
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 horizonor "footprint". Amateur radio repeaters are similar in concept to those used by public safety entities police, fire department, etc.

This is the current normal setup for the Austin UHF network. There are no other repeaters connecting to it by Echolink, only individual users. No IRLP links are connected directly to this network.
I hope you enjoy the blog! Amateur radio is a fun way to mess around with technology, meet new people, and communicate off the grid. Talking directly to another radio on a single frequency also called simplex is the easiest way to get started.
Simple enough for even me to understand! How does a Repeater work? The antenna is used on transmit and receive signals that are going into and out of the repeater.

Both have been very low-cost exercises, at least in terms of wallet impact. The first step for most Technician-class amateur radio operators is checking out the local repeaters, most of which are set up exactly for the bands that Techs have access to. Time to face some cold, hard facts about amateur radio: that spiffy new Baofeng radio I recommended last time as a great starter radio is actually pretty lame. Even if you buy a more powerful HT, or invest in a mobile or base-station rig running 50 or watts, the plain fact is that direct radio-to-radio contacts on the same frequency, or simplex contacts, are difficult on VHF and UHF because those bands are really best for line of sight LOS use.
