Welcome to the home page of G4ATA, G8DYT & M4D.

Hi, my name is John Hotchin and this web site is to tell you a little about me and my interests.  Hopefully you will find at least some of it interesting and some of it informative.  G4ATA probably means nothing to a lot of people - it is my Amateur Radio callsign, hence G4ATA.CO.UK.  I also hold the callsign G8DYT but this call was usually reserved for contest operations until I was issued with the short contest call M4D in October 2012.

In mid July 2015 I moved to Ayrshire, Scotland.  Although I am now "officially" GM4ATA I will keep the same web domain name, at least, for the time being.

Ham radio has played a big part in my life.  I first became interested at the age of 12/13 (around 1969/70) and was an avid short wave listener for many years.  My father was first licensed as G8DYT in 1970 and then upgraded to a "class A" in 1971 and was issued G4ATA.  I was first licensed in 1986 as G1UDF.  After my father passed away in January 1989 I thought it would be a nice way of remembering him by passing the 12wpm CW test to upgrade to a "class A" and have his callsign re-issued to me.  I was successful in passing the test and have been licensed as G4ATA since August 1989.  I also had his first class B call re-issued originally for use in contests.  I have since been successful in applying for a SCC (short contest call), M4D for my contesting activities.
My son, Martin, has also been licensed since he was 13 years of age in 1997.  Martin upgraded his licence to the UK Advanced category (the equivalent of the old "class A") and now holds the callsign M0HOM.
We are both keen DX'ers, contesters and also enjoy building our own antennas.

Due to circumstances beyond my control GM4ATA is currently QRT!! 
My usual station setup consists of a Yaesu FT2000, Dentron MLA-2500b (running a pair of 3CX400A7's), Tokyo Hy-Power 2kw ATU, InnovAntennas 4-ele LFA yagi for 28MHz and a homebrew Moxon for 15m.  The antennas are mounted on a Tennamast telescopic mast, height min 7m & max 11m.  I also have a homebrew 4-square for 40m which is only used for portable operations in contests.  More info and links further down this page.

The buttons at the bottom of the page will take you to relevant sections of the site and it's all pretty self-explanatory.

My Ham Radio News

Please note - all of my QSO's are uploaded to ClubLog.org and LoTW at the end of each day's operations.  QSO's are uploaded to eQSL every 2 weeks.

CQ WW WPX 2015 Update - M4D ...... poor WX conditions (OK some poor planning too!) meant that we had to take down the 10m antenna before there was any possibility of the band opening resulting in just a 4-band entry.  Also, at the last minute, we "chickened out" and decided to run in the high power category!  Still we still managed #75 World, #40 Europe and  #3 England in the multi single, high power category.  Not too shabby considering that the whole station and antennas were only setup the day before the contest started and all taken down the day after.
Many thanks to Martin, M0HOM.

February 2015
I have decided that my next serious contest effort will be a father/son entry in the CQ WW WPX SSB contest the last weekend in March 2015.  We will be in the Multi Single Low Power category and antennas will probably be....
80m - low inverted "V"
40m - 4-square
20m - simple ground plane at 6m agl
15m - homebrew Moxon at 11m agl
10m - 4-ele LFA yagi at 10m
Please listen out for M4D during the contest and G4ATA/P and M0HOM/P a couple of days before and after.

October 2014
My 40m 4-square had another outing in the CQ WW SSB contest, this time chasing another 'G' record in the SOA HP category.  It seems I was within touching distance of the record with 1040 QSO's, 96 countries, 23 zones and 180,642 claimed points.

March 2014
The 40m 4-square performed well during the WPX contest setting a new 'G' record for the SOA high power category.

February 2014
Construction of a homebrew 40m 4-square array for the 2014 CQ WW WPX SSB contest was completed ready for on air testing that took place 14th to 17th March 2014 and during the RUDX contest that weekend.....very pleasing performance for G4ATA/P and 2E1FVS/P before and after the contest and M4D during the contest.    More information here.

January 2014
My NoV for my contest call, M4D has just been renewed.

November 2013
CQ WW SSB 2013 raw results (prior to checking) have been published.  Very happy with my 4th in the World, 3rd in Europe and 1st G station result in the Single Op, Low Power, Assisted 40m category.  TX/RX Yaesu FT-450D, antenna a phased pair of elevated verticals and an inverted V.
Final results published and received 3rd in the World, 3rd in Europe and 1st in England and established a new record for England in the category.

June 2013
Installed a homebrew Moxon for 15m just below my 10m 4-ele LFA yagi.

November 2012
Antenna is now mounted on a Tennamast 9.2m Lightweight Mast.  Including the head unit and stub mast the antenna is now at 11m above ground.  Click here for more information and pics.


Just in time for CQWW SSB 2012 I had M4D special contest call sign issued.
2012 CQWW SSB, 10m SOSB Assisted....770 QSOs, 101 DXCC, 34 zones.


24th July 2012 - replaced my Yaesu FT-1000MP with a Yaesu FT-2000.  Yaesu FT-2000, G4ATA

3rd April 2012
My contest log is now available online here.  My contest callsign is G8DYT.

February 2012
I have now installed a 4 element LFA yagi from InnovAntennas on a temporary mast at just 5m above ground.  DX worked during the first two days of testing includes VK6NB, OD5PY, ZS2DL, ZS6XT, 5B4AIX, FR5DZ and 3B8CF.  Whilst listening to FR5DZ I made some direct comparisons to my old quarter wave vertical with elevated radials ...... on the vertical FR5DZ peaked S3, on the 4 element yagi he was peaking S9+10dB.  An amazing difference.

        

December 2011
After having spent over 12 months battling with PLA, plasma TV and general urban QRM on the low bands (80m & 40m) it has finally worn me down and I have decided to try my luck on 10m!   Due to the limitations of size and layout of my garden I decided to install a 4-ele LFA yagi.  A homebrew Moxon for 15m was added to the mast in June 2013.

Back in the "good old days" I had the honour of being the first "DX" station featured on Comtek's web site after I sent them details of the construction of my full size 4-square for 80m using their excellent phasing system.  Since then DX-Engineering bought out Comtek but their products are still available ...... follow the link.

Click here for my 80m 4-Square project . ....sadly, this 4-square is no longer in existence since I moved QTH in July 2010.

My 4-Square pages and information has generated quite a lot of interest and has contributed to plans for other hams to erect their own 4-Square arrays in North America, Europe and Australia.  If I can be of any help or you would like any additional information or photographs please do not hesitate to contact me - my e-mail address is shown below.  Unfortunately due to my move of QTH I no longer have a 80m 4-square ...... 10m and 15m are now my bands of choice at my home QTH.  I have recently built a homebrew 40m 4-square for portable, contest operations.....link at the top of this page.

4-Square Site  Click on the link here for details of 4-Squares in the UK and around the world - please visit and if you would like your 4-square to be featured then please send details as requested on the site.  During the last couple of years this site has been sadly neglected and updates have been rare.  However, I have now resolved to devote more time to this.  If you have sent updates or information to me in the past and I have not got around to putting them on the site please resend them and I will make sure that they are included and please accept my apologies for not having done them first time around.

Current DXCC totals as of February 26th 2015 (since September 2007.....all my logs prior to this date have been lost in several changes of QTH and a change of XYL!!)
80m - 202, 40m - 188, 20m - 98, 17m - 10, 15m - 218, 12m - 8, 10m - 245, 6m - 5  TOTAL all bands - 279 (246 confirmed)

DXCC Totals 2014 ....... 40m - 114, 20m - 43, 17m - 1, 15m - 135, 12m - 4, 10m - 127  Total 197
DXCC Totals 2015 ....... 40m - 2, 15m - 29, 10m - 47   Total 64   ...............2015 has got off to a pretty slow start!!
