[OKDXA] Interesting Propagation on 30 m

[GARYLM at kiamichiwb.org]

I'M NOT SURE WHAT CAUSES THE EHCO, BT WE USE TO HEAR THEM LOTS OF TIMES IN ALASKA, NOT SURE IF IT IS TRAVELING AROUND THE GLOBE AND COMING IN FROM A SKEWED PATH OR TO BACK OF ANTENNA. BUT IT HAPPENS MUCH MORE IN THE NORTH THAN DOWN HERE.
HOPFULLY SOMEONE CAN EXPLAIN IT.
HAVE A VERY HAPPY NEW YEAR 2022

OK, this is interesting. I've heard this before: there is a long-delay 
echo from MY transmission on 30 m. I've heard thsi before on 15 m, but 
never on 30 m. These never last long and I don't know the cause. I don;t 
have to to hook up a scope to check the echo delay, which would tell me 
the round-trip distance.

If I send a dit, I hear an echo of it delayed about 0.2 s. It is 
definitely mine, and it is not an artifact from my rig because I hear it 
on both my TT Orion 2 and my TS930S. The echo strength varies with time: 
sometimes it's quite clear, others absent r very faint.

Happy New Year,

Kim N5OP
