2230 S9+35  anthem naxt W M Cn news
- interesting echo two-way propagation was observed, words delayed approx. 1 sec 8680 km
the same phenomenon occurs on the Sky Loop and on a dipole suspended 35 m above the ground
the signal level is the same, but the dipole has about 2s lower noise

RobRich:
Different station, but similar happened to me a few days ago.

I suspect mine was simultaneous reception via both short and long path.

Hey All,

 Way back in the day I used to get two path echo at times, particularly on Asian stations  (ie on  R. Japan FROM Japanese soil)  -probably via Polar path and another route at the same time. I thought it was SOOO cool. Some of  my  ultimate Dx was "polished off" with an echo. If heard that effect , I knew it was from FAR away !

The other type of echo I have gotten at times ( heard it lately) is network programming being fed to two MW stations on the same frequency. "Interesting" , but not NEARLY  as "mysterious" or "romantic" as a long haul dx  HF    echoed sky wave  .
