Back again.....the NAB was somewhat depressing to say the least. Back to Dan and the technical discussion of WARM. It is important to note that WARM has not always been on 590. In looking at the original CP study from 1948-49 for WEJL which incredibly I have, WARM is listed as operating on 1400 in Dunmore near I380. It is my understanding that WARM went to 590 in the mid or late fifties. It may not predate some of these nitetime operations. Ultimately, someone needs to do a nighttime skywave study to see what WARM can really do. If it could switch to Class D operation with 30 to 100 watts with a middle valley stick (nighttime); this might be the logical thing to do. The operational reductions in cost would make it viable. Maybe even a simpler two tower directional would be another solution. These "simple" directionals seem to work better and still maintain cost savings. Obviously, WARM needs some engineering TLC
