Using my Home Brew 10W PA and 6m x 6m Inverted L on 630m, ERP certainly no more than the indicated 10mW I got a new distance record last night.
OH8HTG is 2051Km away.

OH8HTG is also active on 28MHz WSPR and doing a test with Horizontal and Vertical Antennas it seems. My 100mW WSPR on 28MHz uses a 5/8 Vertical antenna mounted on a ground post. Reception reports from OH8THG are consistently 3 to 4dB (sometimes more) up when he uses a Vertical antenna.

It is nice to see such tests being carried out.
Today I spotted a smaller SID at around 09:45 UTC on my VLF SID Monitor it was possibly too small to trigger any e-mail alerts.
In this instance it is interesting too take a look at the Goes Satellite Data, this shows us the cause.
The plot from my VLF Monitor shows the effect.
From the bottom :-
Red Pen – Band Noise Increased.
Black Pen – NAA USA Sharp Signal Strength Enhancement.
Green Pen – 16.4KHz Noise Increased.
Dark Blue Pen – GBZ UK Sharp Signal Strength Enhancement.
Mauve Pen – FTA France 2dB Drop in Signal Strength.
Light Blue Pen – DHO38 2dB Drop in Signal Strength.
Orange Pen – GQD UK – Sharp 7dB Drop in Signal Strength.
There has been an increase in Sun activity lately (Solar Flares) whilst it is nice to get e-mail alerts from observers and see captures of the effects from other Hams, it is nice to monitor them live for yourself.
Yesterday I started my VLF SID Monitor and uploaded it to my VLF Grabber. After some tinkering I looked at my mail and sure enough there was a Flare just one hour before I started monitoring proper from then on the signals were flat.
Well tomorrow / today is another day, so again I did some more setting up and ran a fast and slow version with some different stations monitored. There were at least two Flares overnight and early morning while my set up was off, so would I have a chance to see any more.
Yes at 15:02 local 14:02 UTC. The effects can bee seen in the Captures.
Full recovery from this bombardment took around one and a half hours.
I have prepared my VLF Grabber for the United Nations Day October 24, 2014 at 10:00 UTC SAQ transmission on 17.2KHz so I will be running daily until then. The message SAQ is at 10.00 UTC with tuning up from 09.30 UTC.
Take a look at the Video put together by SolarHam.com which shows the GOES Satellite Data, predicted effects and video images of the Flare from different sensors.
