[Lowfer] TAG and Wolf

Tue Feb 10 19:02:54 EST 2009

Hi John,

Guess I'll have to begin crying "Wolf" whenever I think about the opportunity to run signal comparisons between Tag and Wm to see what my mountain soil conductivity does to the effective ERP. Any simple way to add a key down segment at the beginning of your modulation cycle? Assuming of course that you will ever be able to 'break the ice' and reach your Maine property :)  I suppose I could also run in the Wolf mode on occasion. BTW, how's the snow load on your roof??
