28MHz mobile update
After the ‘screaming’ incident with the AT-5555 rig a couple of weeks ago, the rig has seemed quite happy. With the lighter evenings, the band seems to have been open a little longer. By the time I get to the car in the evening, around 1820z there seems to have been just a little propagation left on 28MHz, usually to South America.
For the last couple of evenings, there have been Brazilians to listen to, whilst driving home. Signals have been weak, but I’m hopeful of a contact soon.
Driving around at the weekend, during daylight hours there have been plenty of contacts around Europe and Russia which is good fun for mobile operation.
Soon the Es season will be starting which should be fun on 28MHz.

Ennerdale
Following on from the kind words I received about the scafell pike photo I thought I’d share this one with you. I took it whilst attempting the Ennerdale horseshoe last August. The horsehoe is a 25 mile hike round the summits and it has 21 summits to activate. Some for SOTA (Summits on the air) and some are WOTA (Wainwrights on the air).

The photo was taken from the Summit of Green Gable which ended up being the second to last activation. The clouds came in as did the rain and so I made my way down to the valley floor and had a 6 mile walk back to the car which was parked at the base of the small fell at the front of the horseshoe in the middle of the picture. Crummock and Buttermere are the lakes on the right and Ennerdale lake is hidden round the back of Pillar on the left hand side. The western lakes are not as popular as the central lakes (Derwent, Windemere etc) and even though its only a few miles from a few small towns there was hardly a sole there.
Each year there is a marathon running race round the horseshoe. No cheating you have to go round all the summits! tempted?
Anyway I hope you liek the photo and if you’re ever in the lakes then listen out on 145.500Mhz as there may be someone activating a summit close to where you are.

Last day of Winter
Spring officially begins in about 5 hours from right now. But the weather here today had to be record breaking, or darn near close to it. As I left work today, for the drive home at 5:00 PM, it was 77F (25C) – on March 19th!
The extended forecast for the next week is informing us that daytime high temperatures will be in the upper 60’s and into the 70s’ and that on Thursday, we may even break 80F (27C).
I was telling Bob W3BBO during our weekly Echolink chat the other day, that we will probably pay for this with a Memorial Day holiday weekend in the 50s (13C).
Ah yes, W2LJ is ever the optimist!
On a radio note, I tried getting on the bands a few times over the weekend only to hear not much of anything. The bands seemed to be dead for me. BUT ….. the bands have been real good for my friend Jim W4QO, who announced that he finished working the countries he needed to accomplish Diamond DXCC – all QRP. Way to go, Jim – a hearty hand shake and slap on the back for you!

Geomagnetic data reveal unusual nature of recent solar minimum
An interesting article appeared on physorg.com yesterday regarding changes in the Earth’s magnetic field and its relation to solar activity. Although short on detail it hints at significant changes going on within our sun.
Since the mid-1800s, scientists have been systematically measuring changes in the Earth’s magnetic field and the occurrence of geomagnetic activity. Such long- term investigation has uncovered a number of cyclical changes, including a signal associated with 27-day solar rotation.
This is most clearly seen during the declining phase and minimum of each 11-year solar cycle, when the Sun’s magnetic dipole is sometimes tilted with respect to the Sun’s rotational axis. With the Sun’s rotation and the emission of solar wind along field lines from either end of the solar magnetic dipole, an outward propagating spiral-like pattern is formed in the solar wind and the interplanetary magnetic field that can drive 27-day, and occasionally 13.5-day, recurrent geomagnetic activity.
Recurrent geomagnetic activity can also be driven by isolated and semipersistent coronal holes, from which concentrated streams of solar wind can be emitted.
During the most recent solar minimum, which took place from 2006 to 2010, however, several researcher groups noticed 6.7-day and 9-day recurrent changes in geomagnetic activity, and similar patterns in the interplanetary magnetic field, and the solar wind. Using modern data covering the previous two solar minima, these higher-frequency occurrences were judged to be unusual.
Love et al. analyzed historical geomagnetic activity records from 1868 to 2011 and find that the 6.7-day and 9-day recurrent changes were actually unique in the past 140 years.They suggest that the higher-frequency changes in geomagnetic activity are due to an unusual transient asymmetry in the solar dynamo, the turbulent, rotating plasma deep within the sun which generates the magnetic field.

Linux Outlaw on LHS
The live recording of LHS Episode #079 is being moved to today, March 19th, at approximately 4:30pm CDT (2130 UTC). This is to accommodate our very special guest, Fabian “Fab” Scherschel of the Linux Outlaws podcast. We might even get a cameo from Dan Lynch as well; no word on that yet. So if you can, please join us for the live broadcast and visit with us in the chat room during the show.

Shame on me………………
Early spring+great weather=yard work, house cleaning, garden prep and blah blah blah and therefore it's > (greater than) ham radio which = shame on me! I have not had really any time for radio!
