I will verify the National Park exclusive jurisdictions some time this weekend. Right now I can tell you that Lassen, Yosemite, and Sequoia-Kings Canyon are exclusive jurisdictions or federal islands as they are sometimes called. Death Valley National Park, reflecting its decades long status as a National Monument, is a concurrent jurisdiction, so it is not a federal island. I need to check on Joshua Tree, Redwoods, and Pt. Reyes as those are probably the only likely candidates for exclusive jurisdictions. Everything else, to the best of my memory is most likely concurrent.
If you put the remote base sites on the map as well, I think it would get to cluttered, especially if you try to name each one. If you don't name each one the information won't be all that useful. In my opinion the suggestions I made would avoid clutter and improve the readability. The link provided by jlanfn is a great map, showing not only the bases but the microwave paths as well. Putting all of that on your map would render it useless as each layer of information would be covered by another layer. I've seen a couple of dozen CHP radio system products and your map, along with the changes I suggested, in my opinion, would pull the best of all of them into one product.
I have a fair amount of experience developing map products for publication such as wilderness area maps, National Forest maps, ski trail maps, hiking trail maps, fuelwood cutting maps, OHV maps, and similar products. I worked with illustrators and wrote text. I have a feel for how information is received and then field experience seeing the results of how it is presented. Some of the publications were revised every year and we got to make enough changes until we started noting improvements in the types of questions people would ask, and more importantly the questions they no longer had to ask. Clutter or busyness makes a map very hard to read so you have to hit a line between presenting pertinent information and readability.
The map here is for folks who are keenly interested in details and are more map savvy, but do remember that this map is going to be used in a mobile environment and needs to primarily present frequency, tone, area of frequency use, and unit designator prefix. As I'm driving those are the data I need to keep track of the incidents along the highway that may affect my driving plans. That is my opinion on the objective of this map, and others may have a differing opinion. Perhaps a more detailed map with the remote base locations could be provided to use as a programing tool, something that could be viewed intensely at home and other fixed locations.
I plan to take colored pencils and color in the state's CHP radio system map, keeping in mind, however, that without highway information on it keeping track of the geography of the frequency use will be compromised.
Just my 2 bits worth.
