I know that the 600 Meter Research Group is utilizing QRSS for their
experiments; that was the first I'd ever heard of the mode.
Note that the 600 meter band was the former MF maritime CW band, with
500 kHz being the international CW calling and distress freq'y for
about 80 years. 500 would be jammed at night when the band opened up
after sunset. With the elimination of maritime CW, the 600 MRG
obtained an experimental license from the FCC. You can view their

Hi,
The experimenters there are using plain CW, QRSS in various flavors,
WSPR, and some other digi modes. One of the goals is exploring
"propagation". We are hoping for an amateur allocation there and that
information would be useful. The new allocation would likely be only 7
kc wide! There probably won't be any YaeComWood radios on the band any
time soon so there won't be a mass influx. It looks like voice modes are
right *out*. But it seems like the 'neighbors' there are easy enough to
live with. I have tried to contribute to their studies with my reports
but I have only been able to report a few of the CW transmissions on
that band. My radios are puny and not stable enough for the weaker
modes. Most of the time the resources that are shared on that band are
in use elsewhere - antenna, computer, operator. I'm assembling a crystal
controlled (temp compensated) SDR receiver to help with that. And a loop
antenna. I have no plans to spank my oscillators with gps so one or two
modes might be off the table here. Operator time is still going to be a
problem. I'll be seeing some of you on the new band.

Bill KU8H
