    Hi all,

    there is my post to TB reflector... Anybody has the same experiences for last weeks?

    Hi Tom and Roger,

    I decided to add my 2c as I noticed the same behavior with no GL peak for last weeks
    over here...
    I remember the great peaks during the Grey line phenomenon condx window
    years ago but not now. I tried to observing the condx during the GL window for last
    few weeks on TB (thanks to Xmas time and my illness on ATB) with the similar results
    as Roger reported.
    Also I tried to switch in between several RX antennas like W2PM MiniDiamond loop,
    K9FD loop, low dipole as same as my TX antenna (loaded half sloper) and there was no
    difference regarding the peak at the GL time...

    The band has been open for DX from Europe almost every night this week . . . so let's hear some more activity from you North American guys! (I'm usually on from around 23.30 Z) However . . . I'm still amazed that there seems to be no peak in signals around our Sunrise (in the old days, when conditions were much better, signals would usually increase by at least 10 to 20dB, both ways) Roger G3YRO
