AMS uses Midland channels and sub-channels. The Midland-GXT1000 is a good choice, comes in a 2 pack for ~$60, and will give everything you need. But you can't reprogram it, and any headsets or accessories will be Midland only. A lot of us are running Baofengs, and these offer you the most flexibility. For about the same expense you can get the radio, antenna upgrade, and programming cable. http://www.amazon.com/s/?ie=UTF8&keywords=baofeng+bf-f8hp&tag=googhydr-20&index=aps&hvadid=28510111706&hvpos=1t1&hvexid=&hvnetw=g&hvrand=17880364329185443799&hvpone=&hvptwo=&hvqmt=b&hvdev=c&ref=pd_sl_4sf8pgfes5_b As noted above, there is a steep initial learning curve. It's a good option if you also get a programming cable and learn how to use CHIRP. You probably can't buy one locally.For all things Baofeng see Miklor's site. http://www.miklor.com/uv5r/There's tons of support out there and you probably have time to get a Baofeng BF FH8 (the latest version of the most popular model) and work everything out. Odds are pretty good you already know someone that runs one of these and could help you. And the upgrade antenna, 7" or 14" is absolutely worth the extra $10.
