11 meters

This might be a red herring, but I found this at the Eddystone website : "In the early 1960s a new system of numbering started, to run in parallel with this traditional nomenclature. It was the two-letter prefix of which the first was always ‘E’ (for ‘Eddystone’) and the second was a type designator, viz:
EA Amateur
EB Broadcast
EC Communication
EM Marine
EP Panadaptor (not strictly a receiver)
EY Yachtsman"

Mike P reports : "The 45 metre area has been used for pirate amateur-style activity for many decades ... was certainly active in the 1960's, with most people using ex-WW2 equipment (19 and 62 sets, etc) ... VERY old (1920's) amateur radio publications talk about (legal) use of "45 metres" ... in the 1970's, there was an EC Club run by a Mr Jenkins of West London, and even EC rallies (one of which, at Drayton Manor, was spectacularly raided by the Post Office). In the early 1980's, it was sometimes called the IB (International Breakers) Net, and the operators were usually wealthier CBers using converted Yaesu FT101s and similar. At one time, the Italian company CTE International actually manufactured a CB to 6.6MHz transverter, the TR45 (27MHz in, ten watts of 6.6MHz out) and matching BABO45 mobile antenna (175cm long)"

What 6.6MHz is ACTUALLY for!

The main legitimate use for the Echo Charlie band then is the International HF service - High Frequencies available to enroute stations serving international flight operations on the Major World Air Route Areas (MWARA's), as defined in the international Radio Regulations and the ICAO Assignment Plan. MWARA's such as NAT,AFI,CWP,CAR,MID,SAM,EA,SEA,EUR etc. See http://www.rcic.com/reg/fcc/clauses/87.263.htm for info.

Also LDOC - Long distance operational control frequencies "provide communications between aeronautical enroute stations and aircraft stations anywhere in the world for control of the regularity and efficiency of flight and safety of aircraft" i.e. private airline channels, sometimes provided as a service by a third-party.

You may encounter strong anti-EC sentiment, especially from the arrogant opinionated type of amateur who believes that the Morse code test he passed (often the only real difference between him and the EC operator) qualifies him to call for the hanging drawing and quartering of anyone who has ever so much as received anything outside of an amateur band. According to them, there will be aircraft falling out of the skies any time anyone transmits on a naughty channel. The next time someone says Echo Charlie puts lives at risk, consider the following :

If the demand is there, this sort of thing WILL happen if there is no alternative. If the amateur community (via the national groups deciding ITU policy) had allowed HF voice comms for amateurs without a Morse test, EC would probably have never taken off.

I will say quite clearly PLEASE DO NOT USE FREQUENCIES FOR WHICH YOU ARE NOT LICENSED OR ARE NOT PERMITTED TO USE. Not that I believe that anyone will pay attention to that, but to make it plain that this page is not supporting or encouraging such things. This is for information and entertainment only.

6MHz En-route USB channels, example users

REMEMBER : LSB on 6640 will use 3kHz downwards (6637 to 6640)
...whereas USB on 6640 will use 3kHz upwards   (6640 to 6643)
i.e. 6625 LSB will conflict with 6622 USB.

Echo Charlie operators could help their case considerably by
sticking to "safe" channels and steering well clear of air traffic!

Phil / Surrey :
in the very late 70's through the early 80's I was very
active most nights on 635 lsb from N. London and Dunstable.
I used to use the call Unit 148 mobile.
... there was quite a collection of operators. Frank DT308
Bedford, most everyone knew or heard him, Aaron Unit 990 mobile,
Jackie with her kilowatt out of Crystal Palace etc.
I've mentioned this crowd before in that rarely was anyone
allowed on channel unless they gave most everyone an S9 sig.
This way we were never in the situation of the typical wide
area group discussion where half the people cannot hear the
other half. The only op we let in was Steve in Kings Lynn,
Norfolk as he was one of the few people who could bend needles
in London from nearly 100 miles away.
You have respect for such people.



Surely you must have known Anna...Pizza Lady? I can't remember
her DT number, she blew a lot of smoke from the Dunstable area. 

Frank is still in the boatyard... didn't he have a Polaris Comet
antenna...sometimes used to think he was talking to himself,
I couldn't hear half the stuff he did, not on my old half wave.

Also Tony...Charlie Oscar 118, maybe you knew him? He was near
Frank's QTH, unfortunately he passed away a few months ago
(from Mar 2000).

Simon, 32010 :

Has there ever been a case where any CBer has caused interference
to a public service except where a receiver has just been overloaded
by strong signals? The only things which an illegal CB could do are

1) Cause direct breakthrough on to audio or video equipment. So can
   a radio amateur legally using 400 watts into a 4 element yagi on
   28.005 MHz. So can LF/MF and HF broadcast stations using up to
   2 Megawatts of AM power. What is done to stop these breaking
   through on telephone lines etc. - nothing, the phone lines in the
   area have to be filtered. It is BT who usually has to pay for RF
   filtering on telephone lines. There are MF transmitters using up
   to 5000 watts on sites which are virtually in somebodys back garden. 

2) Overload RF stages in recievers. So can anything. So could a taxi
   firm next door. So could a radio amateur using 400 watts to a 48
   element yagi on 70 cms. So could any broadcast station, many legal
   broadcast stations use 100 watts from the top of tower blocks (so
   do pirates but they are ALWAYS going to interfere with the
   emergency services for some reason). What about people on the top
   floor?

3) Produce a lot of harmonics. So could a home made QRP rig. The
   amateur radio standards for out of band transmission aren't hard
   to meet. Something like no more than 1% out of band. 1% of 400
   watts is 4 watts. Any piece of commercial equipment would almost
   certainly be better filtered than this. Do SSB CB radios go
   through less thorough testing procedures than FM ones? Which has
   the cleanest output, a Ranger 2950 or something built from a kit
   on the 10 metre band which was set up using only a power meter?

4) Upset other CBers. There is always someone who complains about
   hearing foreign people on the CB. They probably believed the RA
   when they said it was a short range band. Yeah, and 10 metres is
   a short range band too, with distances of 5-10 miles expected. 
   What if you were doing CW on 28.02 MHz with a 100 watt radio.
   Wouldn't there be the possibility that local CBers would notice
   a blocking effect on distant signals when your key was down.
   This might become rather annoying after a while (especially on
   channel 40). You have the privilege of being able to cause
   interference to absolutely anything because you can remember
   some dots and dashes.

You might follow the theory of safety in numbers... enough EC operators and they won't bother tracing them all. Not so... where they find you, they'll bust you! You have been warned.

Press Release - 22 February 2002

John Plant, 35, of Clifton Drive North in St Annes on Sea was convicted of illegal installation and use of radio transmitting equipment at Blackpool Magistrates' Court on 20 February 2002. He was given a 12 months conditional discharge, and ordered to pay £250 costs.

Mr Plant pleaded guilty to offences under section 1(1) of the Wireless Telegraphy Act 1949, and was also ordered to forfeit all equipment seized from his home address.

During November last year officers employed by the Radiocommunications Agency executed a search warrant at Mr Plants' home address during their investigations into unlicensed transmissions within the 6.6MHz frequency band, which is reserved for aeronautical services.

On entering the premises they found radio transmitting equipment and other items which were set up to operate on the 6.6 MHz frequency band. The owner of the equipment was identified as John Plant and all the equipment was seized as evidence.

Mr Plant was interviewed and admitted to the officers that he had transmitted on 6.6 MHz band, and did not hold any Wireless Telegraphy Act Licence.

Under Section 1.1 of the 1949 Wireless Telegraphy Act it is an offence to install or operate a wireless telegraphy station without an appropriate licence.
