[HCDX] geomag storm logs from Boston

[Paul V McDonough <pmcdonou@xxxxxxxxxxxx>]

 Here are some logs and observations around local noontime on 29 Oct 2003.
The geomag storm definitely hit. Conditions on all bands are bad. See
logs. Plus the noise floor seems raised, possibly due to rain outside, or
geomag storm.

I'm located just west of Boston, Massachusetts.

WWV check at 1648 UTC (11:48am local eastern)
20000 nothing
15000 het
10000 nothing
5000 nothing (expected this time of day)
2500 nothing (expected this time of day)

So no WWV channel listenable to get solar terrestrial indices at 18
minutes past the hour. Thanks goodness for computers and internet.

Signals in 15 MHz band were present but weak with fluttery signal
strength.  "Strong" signals (S8+, R8 preamp on, 90 random wire) were on:
- 15180 with middle eastern pop music(?) at 1654 UTC
- 15190 with EE woman and recipe (BBC?) - S9+
- 15205 man - UNID - S9+
- 15240 BBC? Nelson Mandela and sports? (S7)

I stopped trolling the band at 15240. I jumped to 15825 and heard WWCR
"only" S9+ (fast fades below S8) with EE religious.

13845, also WWCR, "only" S8+ with music at 1659 UTC.

Then I checked usual loud US stations.

12160 at 1659 usually WWCR, barely heard (<S3 noise)

9475 at 1700 WWCR "Yeshua is coming" only S7+ with fades below S6.

13615 at 1704 assume WEWN with EE religious, "only" S9+

15105 at 1705 presumed WHRI in LOTS of noise, S7, guy singing (voice
undergoing "underwater" treatment - due to geomag storm - assumed).

13760 at 1706 - EE religious - good signal S7-S8

17650 at 1707 - supposed to be WHRA/WHRI - only heard het.

9370 at 1708 - "David slew Goliath" WTJC? - good - S9, fades to S7.

Then I checked the whole 13 meter (21 MHz) band.

21455 very weak modulation, only S3
21470 at 1710 S7 signal, BBC? - fades into S3 noise
21480 - het
21500 - het
21535 - heard weak voice - S4+ to S1(!)
21600 at 1711 - S6+ - UNID male lang - fades to noise <S3
21680 at 1712 - "Genesis ch 1, vs 2" S-meter wavering around S6, fades
into S3 noise
21700 at 1713 - low modulation signal S4-S6
21745 at 1713 - low modulation signal < S6

That's it for the 13 meter band. Fewer signals, much weaker signals.

I should redo this whole scan under "normal" (non-geomagnetic storm)
conditions and show the differences.
