3 hops: PC -> router -> radio -> tower.

I wouldn't classify a 1.2 mile over the air hop as local, particularly the over the air part -- but see below.

This is the part where I'd be inclined to measure twice. When you supply an IP address to ping, how do you know it is the address of something at the tower? It is possible the radio has its own address (cable modems do, for instance). If you have a list of IP addresses from a tracert taken when things are working, you can try pinging each of these addresses and should see very similar results as when running tracert, in either the case where things are working or not. In essence, tracert is automatically sending pings out is succession, one hop further each time.
Another thing you might try is opening a browser and typing the IP address you have for the tower and see if you can get to an admin interface. You should certainly be able to do this with the IP address of the router, to see how this works. Apologies if you've already tried this -- it is hard to find the right level of detail without being insulting and/or writing a whole lot here.
Do you have a list of names that you obtained when things were working (tracerout output but not using the option to suppress DNS translation)? It might be interesting to match this against the list of hops you supplied above and knowing just where things stop when they are not working would be very helpful. It could be further into the network on the other side of the radio link, but I'd suspect this link until I knew for sure it was good.
Are things worse when it is raining, at certain times of day, or any other pattern you've noticed?
Sorry for so many questions and so little actual help!
BTW, if you can get to the admin interface for the radio, you should check to be sure your firmware is current. Same goes for the router, but this isn't likely to be as important in this case.
