If you look specifically for digipeaters (six-pointed stars as the symbol) in the "near.cgi" output you'll get a better feel for the infrastructure near you. 'Course it's hard to tell really how effectively they cover your area without knowing details of how they're placed. You could also set up an Xastir station to listen using an APRS-IS server (nternet only) fairly quickly, and look for the digis on your map. To do this, you'd want to use a filter that specified "r/45/-92/500" or something to give a nice big range of stations near you. I'm actually looking at such a thing right now. In the few seconds I've been watching, I see that there are quite a few digipeaters, but they are all advertising fairly short ranges (through their PHG settings, which may or may not really indicate their effectiveness, as it's a very crude measure). I'll take a screen shot of your area viewed in xastir in an hour or so after I've captured more data. I'll put it on my web site and post here with the URL. -- Tom Russo KM5VY SAR502 DM64ux http://www.swcp.com/~russo/ Tijeras, NM QRPL#1592 K2#398 SOC#236 AHTB#1 http://kevan.org/brain.cgi?DDTNM "And, isn't sanity really just a one-trick pony anyway?
