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.

M0XII/P - UKAC 50MHz Contest - August

The August UKAC 50Mhz Contest on the 26th from locator square IO91MP was excellent with regards to propagation some sporadic E contacts during contest into Spain and Sweden. Activity in this contest was again up this month and it was great to hear a few new stations give away extra multipliers on the band. I managed with a struggle to get three Scottish (GM/MM) stations a few Welsh (GW/MW) stations and one Northern Irish station (GI/MI) and one station from the Isle Of Mann (GD) including a station from (ON) Belgium these were all worked from IO91 Square unfortunately this month I didn't work (EI) Ireland but I could hear Dave EI9FBB on the band but conditions were too weak to complete the QSO. Maybe next month we will get my home country in the log.

This month I finished the contest with a claimed score of 113 QSO's and 15 UK Multiplier squares and a total of 300,390 claimed points with 8 DXCC entities worked. It was really nice to work Hans EA5/DL5EO on his holiday's in JM08AQ Square as my furthest ODX of 1443Km, 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. :)

M0XII/P - UKAC 50Mhz Contest - July

The July UKAC 50Mhz Contest on the 22nd from locator square IO91MP was excellent with regards to propagation some unexpected sproadic E's towards the end of the contest into Sweden and Finland made the band go wild. Activity in this contest was well up on previous months and it was great to hear a few extra multipliers on the band. I still struggle to get GM/MM stations from 91 Square but just about managed to get Andy GM4JR, unfortunately this month didn't hear any EI or GD.

This month I finished the contest with a claimed score of 117 QSO's and 16 UK Multiplier squares and a total of 350,976 points with 8 DXCC entities worked. It was really nice to work Timo OH1TM on the band in KP01VJ Square as my furthest ODX of 1752Km,  Once again a big Thank you to all stations for the points and multipliers this month it was very much appreciated.

“Brendan Quest” Team’s 2 Meter Signal Copied in the UK

A group of Amateur Radio operators from Atlantic Canada is operating from Pouch Cove, Newfoundland, until July 12 in a bid to complete a 2 meter transatlantic contact and claim the Brendan trophy. The "Brendan Quest" team is on the air as VC1T from grid GN37os on 144.155 MHz. The group activated on July 4, and a couple of days later, on July 6 at 1341 UTC, G4SWX was able to completely decode an FSK441 transmission from VC1T.



“They attempted to complete the QSO for 4 hours, but were not successful,” the team reported. “However, this reception should qualify for the Brendan Plate.” The team said a station in Ireland was able to copy parts of three transmissions. Because of the initial success, the group now will use FSK441 exclusively in its Brendan bid.

VC1T had been concentrating its efforts on JT65B, but it has CW and SSB capability, which the team will try if it is able to achieve an FSK441 two-way. Part of the WSJT software package developed by Joe Taylor, K1JT, FSK441 was primarily designed to detect very brief “pings” from meteor trails. VC1T is running 750 W into a rope-supported 43 element, 100 foot long Yagi directed at Europe. It has a gain of more than 23 dBd. When driven with 750 W, the effective radiated power (ERP) in the center of the major lobe should be about 150 kW, the group estimated.

Members of the expedition include Fred Archibald, VE1FA; Roger Sturtevant, VE1SKY; Helen Archibald, VA1YL; Rich Pieniaszek, VA1CHP, and Al Penney, VO1NO. The Brendan Trophy is a series of awards offered by the Irish Radio Transmitters Society (IRTS) to the first Amateur Radio operators to complete a 2 meter transatlantic contact. According to the IRTS, the Brendan Trophy is awarded for the first “traditional mode” two-way contact — ie, SSB or CW capable of being copied without machine assistance. The Brendan Shield is awared for the first “nontraditional mode” two-way contact, ie, digital modes and high-speed CW. The Brendan Plate is given for the first verified reception of a transatlantic signal in any mode.

The goals of the Brendan Quest team are to complete at least one contact on 2 meters using “terrestrial propagation modes” or on both CW and SSB and “non-traditional” modes, such as JT65B. The group plans to operate continuously for the entire period, transmitting on even minutes, and receiving on odd minutes. The Pouch Cove site is 3040 km from the Irish coast and just 23 km from the Cabot Tower site in St Johns, Newfoundland, where Marconi copied the first transatlantic signal in 1901..

The group has a Facebook page, where it is posting updates. — Thanks to AMSAT News Service, Brendan Quest 2 Meter Transatlantic Attempt

50MHz UKAC June Results 2014

The number of entries dropped slightly to 169 as we enter the summer holiday season. Thirty one squares were active which is the highest of the year. (A total of 33 squares have been activated during 2014). This sounds like a repeat of May as the Sporadic-E was dying as the contest started! There were 47 Es QSOs into CT, F, EA, EA6 and EA9. Eighty percent of these were in the first 30 minutes and the final one was at 20:12. Many stations commented that they no Sporadic-e at all. With the high number of active squares, multiplier totals were high with M1MHZ (IO92) working 22 squares, G8XVJ/P (IO93) 21 squares and GI4SNA (IO64) and G3PYE/P (JO02) 18 squares. The best Sporadic-Es contact was between G4LKD (IO93) and EA9PY at 2010 kms and the best tropo contact was between G4RRA (IO80) and GM4ZUK/P (IO86) at 692kms. Adjudication disallowed 5.2% of QSOs with callsigns causing the most difficulty this month.

RSGB VHF National Field Day 2014

The weekend of Saturday & Sunday 5th /6th of July 2014, I ventured out and about with the Middlesex DX group in the VHF National Field Day.

We were operational on 6m, 4m, 2m & 70cm from Locator Square "JO00EW" under the call-sign "M0MDG/P".

We arrived on site on the Friday at 15:00BST and began to set up our portable stations, weather conditions were amazing on the Friday with the sun beaming down on us as we constructed the stations for the contest starting the Saturday at 14:00UTC. Once the stations were put together and tested on the Friday evening Jason M1PRO fired up the BBQ and a tasty meal washed down with a few beers was enjoyed by all.

Saturday Morning everyone was up bright and early in contest mode and once breakfast was had by all and the final tweak's made to the stations it was suddenly 14:00UTC... CQ Contest!!!

I had the pleasure of operating with Carl 2E1IDC on 50 MHz. Simon MW0TBI along with Steve G1OFW operated on 144MHz and John G0KLX with Jason M1PRO operated on 432MHz.

Once 50MHz had finished at 22:00UTC we had to dismantle the station and build the 70MHz setup for the next morning at 08:00UTC. The Guys continued to operate on 144MHz and 432MHz late into the night but as we had very heavy rain and wind in the South East of England over the Saturday night we decided to close down the 144MHz & 432MHz stations as activity almost disappeared. The weather made sleeping in Tents not very pleasant however we struggled on through and managed to get some much needed sleep for the next morning. Everyone was up bright and early and we even got to work the early morning DX into Europe with was greeted with smiles all around once w e Put the finishing touches to the 70MHz station and before we knew it 08:00UT was upon us. 6 hours past and the contest was over at 14:00UT on Sunday afternoon, very weary and tired contest operators then began to disassemble the stations and packed up for our 3 hour journey back home to London.

We finished up the contest with a claimed score and an entry into the Restricted section with the following:

50Mhz (6m):

110 QSO's - 34'294 Total Points with an ODX of 2386Km with SZ8LSV

70Mhz (4m):

63 QSO's - 13'245 Total points with an ODX of 694Km with GM4ZUK/P

144MHz (2m):

230 QSO's - 69'396 Total points with an ODX of 814Km with DK2CF

432MHz (70cms):

85 QSO's - 19'090 Total points with an ODX of 739Km with EI9JA

50MHz (6m) Setup

70MHz (4m) Setup

144MHz (2m) Setup

432MHz (70cms) Setup

I have got to thank the Middlesex DX group (G0KLX, MW0TBI, M1PRO, G1OFW & 2E1IDC) for inviting me along to contest with them for the VHF NFD contest I really enjoyed the weekend it was great craic and certainly looking forward to the next one.

RSGB 50MHz Contest CW

Entered the RSGB 50MHz CW contest yesterday the 29th of June at 09:00- 12:00 UTC under the Middlesex DX Group callsign "M0MDG/P" from locator IO91MP.

John G0KLX from the Middlesex DX group joined me up on the hill were we put together our Portable setup, FT847 with 100W and a 5 Element Tonna Yagi about 4 meters off the ground.

There was Poor conditions on the 6M band with very little Tropo and also UK activity was down, Thank god for some sproadic E propagation to keep us on our toes, we entered the Open section as it was for Portable stations and finished up the contest with a claimed score of 37 QSO's 17,118 Points and "4Z5SG" as our ODX of 3618Km. 

Here is a map of our QSO's:

The Results came out for this contest recently and we cam in 2nd place with 34 confirmed QSO's and 14'029 points with an ODX of 3618km with 4Z5SG  in the Open section delighted with this entry as it was our first time entering this contest and well worth the effort.

It was great fun being out with John and on 50Mhz CW we really enjoyed our first CW entry from the Middlesex DX group, looking forward to the next one. 73's :-)

M0XII/P - UKAC 50Mhz Contest - June

The June UKAC 50Mhz Contest on the 24th from locator square IO91MP was reasonably okay with regards to propagation, Sproadic E's disappeared right before the contest started 19:59:59 :( Activity on the band was up on previous months and was great to hear a few extra multipliers on the band. I still struggle to get GM/MM stations from 91 Square may have to look into a larger antenna for 50MHz.  

This month I finished the contest with a claimed score of 100 QSO's and 15 Multiplier squares and a total of 198,735 points with 4 DXCC entities worked. It was really nice to catch David GI4SNA on the band in IO64XM Square as my furthest ODX of 466Km, I have worked David a few times and even from my Irish QTH but this was the first QSO on 6M under my UK call sign. Once again a big Thank you to all stations for the points and multipliers this month it was very much appreciated.

My working conditions was an FT847 Transceiver with 100 watts into a 5 Element Tonna Yagi up about 4m from ground.

Here's a map of the QSO's made during the contest:

G8T - 50Mhz Trophy Contest from IN79JX

On June 21st & 22nd the RSGB & IARU R1 - 50 MHz International Trophy Contest took place. I was active with The BlackSheep Contest and DX Group under the callsign "G8T" from Locator square IN79JX. I arrived on site on Friday morning and helped the Team put together our station for the weekend.

Band conditions were moderate on the Saturday but then died away on the Sunday morning with almost no conditions on the band but we managed to land "5B4AIG" as our ODX of 3562Km. 

We finished up the Contest with a claimed score of 606 QSO's and 238 Multipliers totaling 159,358,612 points.

I was operating a big pile up on 50MHz and managed to get 102 QSOs Logged in an hour. 

It was an amazing adrenaline rush :-)

Results came out of this contest and we came in 1st place with 577 confirmed QSO's and 638'339 points with an ODX of 3'562Km with 5B4AIG

I got to say a big Thank you to the guys of the Blacksheep Contest group for inviting me along to contest with them. (Pic L>R: Rohan SWL, Stephen G4SHF, Tim G4LOH with the 50Mhz Telford Trophy from 2013, Mike G8TIC and Matt G0XDI including myself with Shackle the Blacksheep mascot) It certainly was a fantastic experience and great weekend with an excellent contest group. Looking forward to the next one. 73's ;-)
