Return Mail to wa1rks@yahoo.com Back in the late 70's I was working AO7 mostly on Mode A, two radios,same stacked 11's,and tri-bander for HF.  had few passes that were below my horizon,no problem for F2 downlink, but was able to get into it on 2m, with passive reflections off nearby MT Greylock,from 1100ft el. to 4k el. discovered it by accident one day, and duplicated it two or three times after.But only on passes aligned with the reflected 2m uplink.Where there is a will, there is a way! 73 ud dx'ing! de Ellis/Wa1rks.
