MSK144

After a month of monitoring the HF bands during the second annual CARC WSPR
challenge I though it would be fun to have the station listen for a
different type of data transmission. Â*With April heralding an increase in
random meteor activity 50, 70 and 144MHz will soon come alive to the chirp
of data bursts from across Europe. Â*A new and interesting mode is quickly
gaining a following in the MS community, MSK144. Â*The name is derived from
the modulation, MSK (minimum shift keying) and 144, the total number of
bits in a message. Â*Not to be confused with the 2m band as its also used on
6,4 and 2m.

The software youll need is either WSJT-X, the experimental version of WSJT
which can be downloaded he
http://www.physics.princeton.edu/pulsar/K1JT/wsjtx.html

or MSHV which is an alternative application supporting popular data modes
at VHF, http://lz2hv.org/mshv

Ive tuned the K3 to 50.280MHz, pointed the antennas east and left the
software listening to the noise. Â*A useful feature of both bits of software
is that they can send spots to the PSK Reporter website. Â*This allows you
to see what youve heard, a bit like wsprnet. Â*In the last 24 hours these
are the results:

A total of 19 DXCC in 24 hours. Not bad considering that 6m appears dead
and the meteor rate has yet to pick up. Â*If youd like to hear more come
along to the VHF propagation talk in May. Â*In the mean time get listening
on 6m. Â*You might even take the plunge and make a few QSOs.

Crawley Microwave Round Table Program


Sunday 18th September 2016


Again this year following we will be holding a heat for the UK Microwave
Group,

annual Project contest for the G3VVB trophy. Please do bring along your
constructed
equipment or project and enter. Entries do not necessarily need to have been
finished during the last year.Please note that the contest will also accept
software
entries as well as hardware. The winner of this round will go on to be
considered,
together with entries from all the other round tables over a year both
before
and after this event.
The morning will feature the usual ‘bring and buy’ sale, so if you have
something to

sell then please bring it along. The Crawley club also intend to sell the
majority of
the late Derek G3GRO’s microwave equipment at this event, although no
details
of the contents are currently available.
Mike G3LYP will be happy to bring any chip components from the UKuW Group

chipbank to you at the meeting. If you have a forthcoming project then why
not
contact Mike beforehand to place your orders,which are free for UKuW group
members.


The program this year as ever offers the microwaver something different –

come along and have a good chat, support the construction contest heat and
hear the talks.

IOTA Contest at CARC

Posted: 26 Jul 2016 09:41 AM PDT
http://carc.org.uk/2016/07/26/iota-contest-at-carc/


This weekend is the RSGB Islands on the Air (IOTA) contest. It runs from
1200UTC on Saturday for 24 hours on all the normal HF bands.

As a first for CARC Im proposing we try a 12 hour multi operator SSB entry
from the club.
Well be using the short contest call G3M which is allowed in this contest.

All club members are welcome to come along and have a go or just find out
what its all about.

Im expecting at most about 500 QSOs in the 12 hours so the rate wont be
frantic and should be within the abilities of everyone who fancies having a
crack.

Hope to see you there.

Mike, G0KAD

About Us

/about


CARC is an Amateur Radio Club based in The Tilgate Recreational Area of
Crawley near to the K2 Sports Centre, whose members share a passion for
Amateur Radio. Amateur Radio is a hobby dating back to the early 1900s when
the radio communications and technology we take for granted today was
developed. Designed by individual hobbyists as well as Commercial
companies. Amateur Radio experimenters and operators were responsible for
many ground-breaking advances in radio communication, and who are still in
the forefront today.

In 1901 Marconi broadcast the first transatlantic radio signal between
Cornwall England and Newfoundland in Canada. He sent the letter ‘S’ in
Morse code, three short ‘dits’, It does surprise many that Morse code is
still widely used today. Audible tones are often the easiest thing for
human ears to hear weak signals above the static and noise of the
airwaves,this allows Morse code to remain a reliable method of
communication when others methods fail.

However Amateur Radio has moved way beyond the dits and dahs of the last
century, Mobile phones and Wireless internet connectivity have
revolutionised the world as we know it – both these technologies have
evolved from the original communication methods developed by Marconi, Hertz
and the other early radio pioneers. Amateur Radio too has exploded with
creativity. Nowadays, you’ll find Radio Amateurs talking directly to
Astronauts on the International Space Station, developing Software Defined
Radios techniques where solder, components and wire are replaced with lines
of computer code, using Amateur Radio satellites to communicate worldwide,
Television, travelling to obscure islands to set up radio stations or
entering the many competitions running frequently on the Amateur Bands.
Many Amateurs still build their own equipment with which they communicate
World Wide.

CARC members do all of this and more. Come and visit us to find out more.
