[Elecraft] 630 meter band open for use

[Don Wilhelm]

Yes, +20 dBm would do it if the antenna and transmission line efficiency 
were a perfect 100%.  A no-loss transmission line and a full size dipole 
or vertical.

With the small antennas (with respect for wavelength) that are typical 
for that band, very low antenna and transmission line efficiency is most 
likely quite low.

EIRP is stated to account for those losses, and more power will be required.
