About twp weeks ago a group of 4 khz spaced birdies showed up on 160 , 80
and 40 (not harmonically related ) For instance on 160
1827.970,1823.970,1819.970, 1815.970 ,1811.970 - clean as a whistle and
stable - tonite 80 starts at 3495.93 and stops at about 3573.93 hard to
tell in QRN.
.
Strangely 3510.93 and 3563.93 are inaudible if they are there , 40 starts at
7023.85 and stops at 7047.85
Anybody have ideas what this stuff might be coming from ? I cannot detect it
in my house with my portable rx probing around.
40 M has very deep nulls off end of my 40 m rotary dipole
