Bob,

Have you looked at the "William Hepburn's VHF/UHF Tropospheric Ducting 
Forecast" found at: http://home.cogeco.ca/~dxinfo/tropo.html? Some part of the 
country experience enhanced band conditions from time to time. Are you suggesting 
that Digis be turned off during periods of enhanced band conditions? During 
those times, my Digi will hear more than normal. The time you extracted the data 
from FindU must have been during especially good conditions for my area. 
Normal number for my Digi fluctuates between 12 and 21 stations heard. That's no 
where near the 85 that you reported. I have the only Digi in the county and 
located in the northwest corner. There are no Digis in the counties west and north 
of this area. To reduce antenna height or gain would not serve the local APRS 
community.
