[TheList] Marlborough Police/Fire Interference

Sun Dec 21 19:02:23 AEDT 2014

The 10.7cm solar flux has been well over 200 for the last few days (although
its back down to 198 at the moment) so the Maximum useable frequency will be
well up towards the VHF range. I've been working into Europe on 25 and 28
MHz with digital modes using 30 watts with  good signals both ways over the
weekend.  Lots of DX activity noted on 27MHz CB also.  So it's possible that
you are getting signals from beyond Oz.

See the following from the IPS website http://www.ips.gov.au/Solar/1/5

             21 Dec             22 Dec             23 Dec
Activity     Moderate to high   Moderate to high   Moderate to high

COMMENT: Solar activity was High for the UT day, 20 December, 
with an X-class flare and several C-class flares occurring from 
active region 2242. The largest flare over the UT day, 20 December, 
was an X1.8/3B from active region 2242 (S19W45), peaking at 20/0028 
UT with associated Type II sweep (shock speed ~850km/s). LASCO 
C2 imagery shows an associated CME to the southwest. Based on 
Enlil model this CME is expected to have a glancing blow on 22 
December. CME occurring on 17 December has not arrived yet and 
appears to have passed south of the Earth. Expect Moderate to 
High activity over the next 3 days. Note there is a low to moderate 
chance for X-class flares. The solar wind speed ranged between 
340-400 km/s over the last 24 hours. The IMF Bz component ranged 
between +/-6 nT. Expect the solar wind speed to remain in this 
range until arrival of expected CME (associated with M6.9 class 
18/2158UT flare).

Seems to be considerable interference on the 75.450/75.500mHz channels
today. Does not seem to be the regular 'skip'from Aust. Country Police
Districts that is heard over this side of the ditch at this time of the
year.
