CARS Contest Call-Sign M2T

CARS is privileged to have been re-issued by Ofcom the Contest Callsign M2T for 2008 to 2011.

"M2T" is a derivative of 2MT (Two Emma Toc.....the phonetics used in 1922 for the first broadcasting station in England).)   M is one of the International letter prefixes allocated to England.     "M" was originally for "Marconi" and latterly for "Maritime".

M2T can only be used in International Contests.   These include: -

ARRL DX (CW & SSB)
ARRL 1.8MHz (CW Only)
ARRL 28MHz (Multi-Mode)
ARRL RTTY Roundup
CQ WPX (CW RTTY & SSB)
CQ World Wide (CW RTTY & SSB)
CQ World Wide 160 (CW & SSB)
IARU HF Championship (Multi-Mode)
RSGB IOTA (Multi-Mode)
WAE DX (CW RTTY & SSB)
BARTG RTTY
IARU 50MHz Trophy (Multi-Mode)
IARU 144MHz Trophy (Multi-Mode)
IARU 432MHz - 248GHz (Multi-Mode)
March 144/432 MHz Contest
May 432MHz - 248GHz Contest
November Marconi Memorial 144MHz Contest

As part of the Notice of Variation to use this Call-Sign, Ofcom require at least 7 days notice of the QTH which the Call-Sign is proposed to be used at.

Distant stations are keen to note that M2T is used from Chelmsford, "Birthplace of Radio" but often challenge the short call-sign and question whether they received it correctly.

CARS M2T QSL Card is extremely sought after.

Operating on Sat, 27th October 2007 from QTH of G3EDM - Chelmsford

Unfortunately the DX bands were hard going due to severe Amateur induced QRM together with a K Index of 3 & no solar flares for 22 days.
Having said that everyone with a microphone was shouting "CQ Contest"!.

A beautiful display showing the audio available over a 50KHz slice of the 7MHz Band.   It is from 7.055 to 7.105MHz.

Look for small blocks of solid light blue - this is solid audio from powerful Contest Stations calling CQ.
A very good use for this is to look for a spot frequency which is not actually occupied - difficult at this time.

Murray tells us that the Receiver is called a SDR-IQ from RFSpace in America uses Spectravue Software which is very good.   The tuning "dial" is the small red bar at the top of the screen (just below 7.085MHz).

Steve tells us that we worked 429 contacts which we think is very good.

Thanks to Geoff & Siliva for opening their house.
