JB007,
I tried to answer using my Iphone and it was not successful, so here is what I was trying to say.
I use myGMRS all the time and here in greater San Antonio, there is a linked repeater setup that covers most of the city. If I was a traveler coming through San Antonio (say on I-10 or I-35), it is not a simple, consistent process to locate the repeaters that are linked along my path so I can try to get the best overall coverage as I travel. In SA, there is a website that talks about our linked repeaters, but an outsider would have to search it out and it might not exist for other cities. So, as a traveler, it would be cool if myGMRS, or some central source let folks look it up.
Specific metro areas that I need to look up the hard way will be El Paso/Las Cruces, Tucson, Phoenix, Eastern LA, Calif Central Valley, SF Bay area, and so forth.
Thanks, JimInHelotes (73s, if you are also a Ham)
