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.
