Hello to all newcommers
Hawe U newer worked on HF, special on 14 MHz with a directional antenna
Its quite often U hear echoes ther.
Its imposible to build an broadbandecho with an simple taperecorder.
And Why the Echoes will bee heard more often when its an high sunspotactivity
That at it beguin to appear in 1970:s was that at SSB then com in use
for all.
U cant hear the Echo on an AM signal it coming as an interfering then.
( I now meant ECHOES upp to 1-5 secund, not Long Delay Echoes )
When I heard my self from on my mobile rig 1977 I can say 100% its was not
a signal fom an taperecorder.
