Hi Alan,

Some would complain that is isn't radio but current carrier 
communications. Either way if it works, I say go for it...hi hi...

I'm waiting to see the day those guys cross the pond on the 8kc band. 
Wouldn't that be something cool...It would be good to get some North 
American stations going on the band to see if the band does open for DX 
at the power levels the guys are experimenting with. Could you imagine a 
audio tube amp pumping out a kilowatt or two? hi hi...
