Right now, very few people<br>in the SAR community have their radios set up for it, so counting on the<br>availability of TEMPn-N on searches is not a safe bet just yet. But if you<br>set your own truck to do TEMPn-N, then when you know you aren't reaching<br>a wide with your handheld on a search, and you know you can hear your truck,<br>you can tinker with your path to use TEMPn-N for a while to be sure of getting<br>out.
