[TenTec] OT: Field Day Drill - intermod issues

[Richards]

Great...    just the sort of answer I can use !

I was hoping for a groundswell of information on it... so I could be the 
best informed guy next year...  I will have to Google and read my 
Antenna Book and ARRL Handbook and study up on it.   The K3 guys point 
to us TT guys, and say our rigs are bothering their rigs, so it we are 
the problem, but I don't think so - but cannot yet explain who is the 
problem or if nobody is, and will need a solution regardless of who gets 
the blame.  (Man... I do NOT want to get into a brand war over it...)
