After many delays, the FCC has approved two new bands. These cover 472 - 479
kHz (630 meters) and 135 - 137.8 kHz (2200 meters).
We are allowed 1 watt EIRP on 2200 meters and 5 watts EIRP on 630 meters. Modes
allowed include CW, RTTY, digital, and phone, although the bands are so narrow
that phone does not appear practical. I expect these bands to focus on CW, JT9,
PSK31, and other narrow-band modes.
You do not need antennas 300 - 1000 meters long to work these bands. Short,
loaded verticals are the way to go. See
http://njdtechnologies.net/whats-the-dumbest-antenna-ive-ever-tried-on-630-meters
for simple antennas that work.
Because antenna efficiencies are *very* low, you should plan to run at least
100 watts in your quest for something approaching 1 watt EIRP.
See http://njdtechnologies.net/630-meter-class-de-amplifier for an example.
