28 February, 2011

ROS  opens the  forgotten band , 5.367 MHz
On a  frequency  where time delay and  phase  distortion over
long paths  severely disrupt conventional   data  modes ….
ROS HF-4 , 25  watts  to  a 35  ft  vertical  resulted  in a  surprise
decode  from RN6AM  ,on a band  normally  considered  closed
during  daylight hours  to  all  but  NVIS  propagation , quickly
followed  by  spots  from Europe and the  UK
