Hi All,
Wanted to report I had successful reception of SAQ 17.2KHz Sunday
morning at 12:30 UTC! Somehow I overslept the 09:30 UTC transmission but it may be
just as well as I was able to really dial-in my receiving setup before the
12:30 transmission.
SAQ was about RST 329 and copy was good - light static on the band
and the signal was not too strong but very readable and clear. My CW is a bit
rusty and I was only getting bits and pieces of their copy - it sounded like
they were sending about 18WPM. If they had sent about 10WPM I think I would have
gotten solid copy. Sorry I didn't have a battery tape recorder to use so
wasn't able to record the transmission. If I had recorded it I could have gone over
it a few times and I am sure I would have gotten solid copy of the message.
The transmission lasted 5 minutes. I did send them a reception report - not
sure if anyone else in the USA heard them but now I have a good idea of exactly
what to listen for and what kind of signal strength to expect. If anyone else
in the USA East Coast has a reasonably quiet location they should have been
able to copy them also.
I owe my successful copy to using a Hagan large ferrite-core loop
receiving antenna with converter and using a battery-operated receiver. The R-389
would have done a good job but I had to be able to divorce the receiver from
the power lines in order to get reasonable copy down at 17.2KHz. I ended up
using a Drake R8A on batteries. After cutting the main breakers to the house I
found that by carefully aligning the loop I was able to null out about 80-90% of
the awful power-line harmonics and noise that was normally running about S-7
on the Drake R8A S-meter. I was able to null the power-line hash down to about
S-2 - S-3 on the meter and I don't think I would have been able to copy SAQ
if I wasn't able to null out the noise. When I switched the house power back on
I was unable to null the noise and it was a constant S-7 on the meter which
would have made copy impossible. I sent them a signal report and mentioned that
I hope they would be able to make another transmission sometime during the
winter when conditions are best. 73 Todd WD4NGG
