Hi,
My name is Steve, G0KYA, and I am a member of the RSGB's Propagation Studies Committee.
A few years ago we did quite a lot of greyline research, which can be read at:

Our group is once again very interested in using WSPR to do some 80m greyline or Sunrise/Sunset enhancement tests and would be interested in hearign from anyone who regularly has their system running on 80m - presumably 3.52960 MHz USB.
I will be leaving my system TX/RXing with 5W (37dbm) to an 80m OCF (Windom) over the next few days to see what I can catch.
I would be interested in hearing from anyone in the USA or far east.
Regards, Steve G0KYA
