[amsat-bb] echo

[andy thomas]

This morning I recorded Spectrum Labs screen dumps 
showing pulses received at around 0632-6 utc on 6.7925
MHz CW.

It was my first intstallation of Spectrum Labs and I
wasn't centred on the signal, so I lost some intital
longer bursts that I briefly saw.

On measurement against the 5 second marker intervals
set by my radio clock the recorded pulses seem to be
around 3 seconds long peaking in the middle of the
fourth/fifth/first seconds  (of a sequence of 5).

Rig is a ICOM IC728 transceiver and the antenna is
actually a trap dipole for 14/21/28 MHz but loaded
onto 7MHz with an ATU. The Dipole is oriented N/S and
the Moon was predicted (in Starry Night)to be dropping
rapidly below my horizon from say, 50% visible at
0630,to my NW off full beam. 

At later times there was predicted to be no moon and
in signal terms there was nothing there on either
frequency as sked after 0638. 

I have reported this observation to Haarp and to the
uk radio astronomy group.
