Tim sounds really good for 25 watts. Makes me not too concerned about my 40 meter class E rig that only does 50 watts... it's good enough.
According to Google Earth, Tim is 350 miles from Jeff and I am 225 miles so, yes 25 watts will do it if you have a good antenna system and that, Tim has. I have just a 160 meter ant system but I was running 350 watts depending on what meter I am using
About the Kerchunk, I notice that when I put the hammer down, the watt meter goes up to about 700 watts. I wonder what the Kerchunk would measure on a scope? Maybe a few KW's?
