On the first transmission, (Jan 19, 05:00 UTC), I tried using an

Anyway, with the narrowest (2 kHz) bandwidth on my old R-1000, it

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.
