There is a campaign underway to get a new band allocated for amateur radio at the 600 metre wavelength (500 kHz). You can read about it at the website of the ARRL 600 Meter Experimental Group. There are some amateur experimental stations authorized to operate on these frequencies for purposes of evaluating its prospects for amateur radio. Early this morning I caught one of these stations:
- WE2XGR/1 in Wayland, MA, USA on 501 kHz at 0436 UTC with a good signal (RST 569). The station was operating in beacon mode, repeating its ID. The operator is K2ORS.
