Street Medic Wikia (beta), the online resource for street medics that anyone can edit Background. • Radios can be a hugely useful tool. 1. Enable us to know where other teams our, ask for more skilled assistance, know the best transport routes for evac., etc. 2. Help you feel connected to what else is going on. • Drawbacks. 1. Can interfere with your situational awareness. Person talking on the radio will be “in a bubble.” 2. Can be undependable. Often fail at the worst possible moment (darkest, wettest, farthest away). 3. Costly. A rented UHF can cost over $300 USD to replace.


Equipment options:

• UHF Radios. Ultra high frequency. 300 MHz and 3 GHz (3,000 MHz). Generally line of site, powerful enough to call around or through urban buildings. Technically require license to operate (rental includes the license). Units generally programmed to a few channels. Units can be purchased on line and then reprogrammed if you know what cannels are being used at an action.


• Base Stations and Repeaters (used with UHF radios): 1. In a typical network the radios have to all be within 2-3 miles of each other for everyone to listen and speak to everyone else. The trick here is that the 2-3 mile radius has to be “line-of-sight”, meaning, in order to use the maximum radius, there cannot be any obstructions, like buildings or mountains. 2. A Base Station is typically set up at Base Camp. The Base Station is, for lack of a better term, one radio (usually a UHF) on steroids. It can send and receive signals much farther away than a typical radio. The Base Station will ensure clear communication between one point and any radio within its’ circular range. This set up works well in rural situations/campaigns where you have a base camp, often with an large di-pole antenna hoisted into a tree. 3. 4. A Repeater is used to ensure clear communication between two or more radios that would not otherwise be able to communicate. This situation usually occurs because there is something in the way, for example, buildings, or a mountain. If you have one radio on one side of a mountain, and another on the other side, the people holding these radios would not be able to communicate with each other. The solution is to place a Repeater in a location that will have the best possible line-of-sight on both radios, in other words, the top of the mountain, and raised as high as possible. When one person speaks into their radio, the repeater will receive the signal, and then repeat it down the other side of the mountain to the other radio.
