[CQ-Contest] What RF voltage OK at Rx in SO2R? THANKS

[Jerry Flanders]

Thanks for the help, guys. Looks like I can safely get on with QRP and work 
up from there. The antennas iI will use initially are 150 feet apart, one a 
fixed horizontal dipole and the other a fixed vertical dipole. I will try 
to measure voltage in several configurations for reference. If I get 
anything that might be useful I will post it here.

Again, thanks and 73
