[600MRG] 630m ground-wave testing - we need more than anecdotal comments

[Ralph Wallio, W0RPK]

Thanks Marshall ---

A little searching finds evidence that you may be an expert user of 
WAGSLAB.  Perhaps you would be interested in contributing this expertise 
to our ARRL 630m Experiment by discussing WAGSLAB results for the test 
paths in the table.  What information do you need for WAGSLAB input that 
is not already provided?

Using these values and GIS terrain maps, the WAGSLAB code is probably the most accurate and tested groundwave path loss/received field strength prediction program. If any of you want more info. I will provide references of if serious about predicting groundwave coverage over irregular, inhomogeneous terrain with or without buildings, foliage and snow let me know and I will send copy of Arcone and windows GUI version of WAGSLAB. 73, Marshall, W1HK #41.
