M0XII/P - UKAC 50MHz Contest - September

The September UKAC 50Mhz Contest on the 23rd from locator square IO91MP was hard going with very little propagation to the North of the UK. Activity seemed down in this contest compared to previous months. I managed with a hard struggle to get EI in the log from IO91 Square heard two stations in EI this month but only completed the QSO with one and worked GI/MI a couple of moments later but I didn't hear or work any GM/MM or GD/MD or GU/GJ on the band, conditions were just too weak to to the North this month. 

This month I finished the contest with a claimed score of 84 QSO's and 14 UK Multiplier squares and a total of 133,868 claimed points with 4 DXCC entities worked. It was really nice to work Joe EI3IX in IO53KU Square as my furthest ODX of 602Km, Once again a big Thank you to all stations for the points and multipliers this month it was very much appreciated. Looking forward to the next contest. :)

My working conditions was an FT847 Transceiver with 100 watts into a 5 Element Tonna F9FT Yagi up 5m from Ground.

Here is a map of the QSO's made during the Contest:

Transmitter Noise

An interesting article I read in the IRTS news bulletin:

Many of us are familiar with the work done by Rob Sherwood NC0B over the years to identify rigs with poor strong-signal performance on receive - of particular relevance to contesters and DXers

http://www.sherweng.com/table.html

Jim Brown K9YC has now done a similar exercise, except he has measured the trash (key clicks, inter-modulation distortion, and phase noise) generated by some popular

rigs on transmit. If you're thinking of buying a new rig, it's worth reading this first.

September 144 MHz International Trophy Contest

This weekend the 6th & 7th of September is the RSGB & IARU 144 MHz International Trophy Contest takes place. 

I will be active this weekend with The Black Sheep Contest and DX Group under the callsign "G8T"  from QRA: JO01KJ 

I'm hoping to give a bash on CW & SSB throughout the weekend so hopefully conditions will prevail. 
If you hear us on the band do feel free to give a shout, it would be great to work you over the weekend.

Here's some videos of our previous contests;

Looking forward to the weekend, see you in the contest.

Footage of powerful solar flares released by Nasa

The US Space Agency NASA has released new footage showing a series of powerful solar flares. There have been a number of eruptions on the surface of the sun in the last week.

Some have warned that this explosion of energy might have a serious impact here on earth.

Newly Formed UK Island Group

This weekend on the 6th & 7th September 2014 the newly formed UK
Island group will be signing M0UKI/p from the rare Farne Islands ( IOTA EU-109 ).

Team members EI9FBB,G0VJG, G7GLW & M0OXO will be QRV with 2 stations and aim to give this IOTA to as many chasers as possible within the short time frame. (Dave EI9FBB mentioned that special attention will be given to work as many EI's as possible too!)

QSL's via M0OXO.
