Ham makes EME contact with just 25 watts
Scarborough Evening News, UK, has announced that Angus Young(M0IKB), 42, a postal worker for Royal Mail from East Ayton believes he has set a new record after communicating with a radio ham in the USA via the moon, or EME as it is known.
He used a homemade antenna and the lowest amount of power ever recorded to achieve this communication - just 25 watts! (More info below)
Overall, Angus estimated his signal covered more than 500,000 miles bouncing off the moon to reach his correspondent in Ohio. He said the received signal on CW was brilliant.
The previous UK record was 50 times what he used - 1250 watts! Angus said: "I am thrilled to have made the new record. Twenty-five watts is a very small amount of power, the same amount which is needed to light up a car tail-lamp."
Regretfully, the newspaper did not mention the call signs of the amateurs involved and the date of the achievement.
Checks are currently being made to see whether Angus' contact broke any international records

My name is Angus and my main interest's are VHF and UP. At the present moment I am a QRP
station with a single homebrew 9 element yagi for 2mtrs and 2 x 14 element
homebrew yagis for the 70cm band which are indside the house roof. My radio is
a humble Yaesu FT817 running very low power levels, into homebrew yagis . I
have also built a satellite array which is as follows: 1 x 5 element crossed
yagi for 2mtrs 2 x 12 element crossed yagis for 70cm, complete with remote
polarisation control. The array has full azimuth and elevation control and was
built completely from junk and cost less than 100GBP to build.I also want to
add 4 x 26 elements for the 23cm band and a small 80cm dish for 13cm band. I am
still working on trying to get the 23cm radio to work as it was broken radio
that I was given. I have just passed my Advance exam and old callsigns are as
follows: 2E0BAT, M3IKB. Hope to work you soon. regards Angus (friends call me
Gus)
UPDATED 10th Jan 2008 I have swapped the 2 x 14 element 70cm yagis with some
much longer spacing 15 element yagis that I am trying out again in the loft. I
have also swapped the 9 element for a homebrew 7 element yagi which has the
same boom length, again in the loft. I am pleased to say that my indoor
homebrew 3 element 50mhz yagi and 5watts from my FT817 resulted in the 1st UK
to ZA contact using JT6M, please see
http://www.g0che.co.uk/g-jt6m-firsts.php?uk=g&sort=2 for details.
UPDATED 14th January 2008 With my indoor 144mhz long boom homebrew 7 element
yagi and 25watts of transmit power I worked Gary KB8RQ on 13th January 2008 @
21.11hrs with EME (moon bounce) although Gary was 6 000km away in Ohio, USA. The
total distance travelled by my signals is over 500,000miles! Very pleased with
the contact and shows that the simple homebrew antenna (£10 in cost $20 USD)
works Great ! Not bad DX on the 2 metre band hi hi
