On the first transmission, (Jan 19, 05:00 UTC), I tried using an
oscilloscope to see if I could see the echo. *It was a 4 second cycle
with 2 seconds on and 2 off. *(Which made syncing the scope (with a 5
second sweep) a real pain. *The next pulse was going when the first one
ended, triggering it again).
Anyway, with the narrowest (2 kHz) bandwidth on my old R-1000, it
just didn't cut it. *When the outgoing signal was S9+10 (in Seattle)
I thought I might have heard an echo or two, but just couldn't be
sure.
What bandwidth were you successful listeners using?


2 kHz in USB mode on a NRD-535D tuned to 6792.0 kHz and 7407.0 kHz.
The cycle (per the HAARP website) was 5 seconds. * *2 seconds on,
followed by 3 seconds off.
