I meant the SRTM1 maps. http://dds.cr.usgs.gov/srtm/version2_1/SRTM1/ I've used Radio Mobile and SPLAT!. I never got a warm and fuzzy with Radio Mobile. Of course, it is a bit more complicated to use SPLAT!. I've used both. Radio-Mobile has a very steep learning curve. Important functions are buried deep into obscure menus, useless trivia is scattered all over the menus, there's no logical sequence of operation, and many of the terms require expertise in cartography. Debugging errors is tricky as important items, such as the performance characteristics of the radios, are scattered over a half dozen menu pages. I find myself constantly referring to my cheat sheet in order to get anything done. However, I haven't found anything else that even comes close to what it does. One obvious advantage to SPLAT! is it can analyze very large areas. Not all that useful in the case of this wifi setup, but very useful in sigint. http://www.qsl.net/kd2bd/splat.html Splat is somewhat easier to use, but as you note, is designed to display repeater coverage. It's less useful for close in coverage, or showing coverage details, as in mountainous or urban jungle terrain. Both programs put considerable effort into implementing complex terrain models. For 2.4 and 5.7Ghz, optical line of sight is close enough. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |
