Interrupt Modulated(IM) QRQ CW Mode - Live demo on the VLF band

Interrupt Modulated(IM) QRQ CW Mode transmitting and receiving digital information using an analog carrier where the required bandwidth is limited to approximately the frequency of the analog carrier signal. The method is called interrupt modulation and consists of interrupting an un-modulated carrier signal so the interruptions correspond directly to the [CW]digital information to be transmitted.

Hi Chuck. Thanks for the warm welcome. I don't know exactly when i'll be up and running from here. I have a few problems to workout first. I'm in a condo on the top floor(3rd) with 220 other units here. I face a courtyard and my balcony can bee seen my many others. This condo has antenna restrictions etc. so i'll have to run in the stealth mode. We will see what happens..Maybe a indoor 40 mtr loop?? Hope to catch you on the air.73's

Chuck I am trying to promote CW right here in my own home.
I have ordered parts for an interface as described on page
http://docs.google.com/Doc?id=ddw2g8w8_9fkz7xj
I think you wrote that page. It looks pretty basic. I am not sure where the positive voltage is applied, or what voltage it is run at. Or is the sound card supposed to supply enough power to run the circuit?

HI Chuck

Tnx for the welcome as well as the back ground info on the CW IRLP project. I hope to meet up with you guys on that mode down the road.

Hi Chuck,

Yes I am presently training to improve my QRQcw copy. I use JustLearnMorseCode and MRX, as well as converting text lists of the 6800 most common words by means of ebook2cw. ( I can copy 24-27 wpm (using 41-44 wpm letters) using a computer keyboard. I spent the last two days trying to get CWirc and CWCOM to work on Windows and was just about to sign on with QSOnet when I found your site, which may be more what I am looking for. I would like to be able to head copy 36 WPM without error, and would dearly love QRQ at 50-70 wpm.) I was licensed in 1960 as a Novice and then in 1976 as an Advanced, and 1984 as an Extra passing the 20 wpm code test. I let my license lapse as I went back to school and was recently relicensed in January of 2009. I had a Yaseu FT101 and this year acquired two HW16's in anticipation of working more CW,

I downloaded the newest fldgi, Mumble and Wondershare. Thank you for putting the instructions for installation in a couple of places and formats, as this allowed me to setup and configure these software apps. Can you tell me which IRC channels are hosting qrqcw conversations, and if this setup is also used by others to work code on the chat channels.

Hi Chuck,
I have not been able to make CWirc work in Windows: it needs to have cwirc.so to be compiled in python or delphi so that the xchat that has been ported to windows can pick it up inside of xchat as a recognizable plugin.

I obtained the 6815 most common words from a website. This is a 'magic number' of words, since it is approximately 95% of all words used. (As you are already well aware) word usage varies depending on whether we are talking about all television scripts, or all novels, or all English usage per the big big Oxford dictionary. But this list should be nearly everything.

I have stayed away from chat rooms since 1994 when it became clear that these were largely unregulated or that there could be harm done to my computer. Because of that, it is somewhat difficult to be aware of the logon procedures etc. So I would really appreciate a really elementary list of how to log on and where to go etc. It seems we could open a IRC channel as #qrqcw_mumble and begin qso'ing. Also, I am lost as to where the main iCW website would be as I only found 11 messages on googlegroups. So I need some pointers.

I got out rufzxp again last night. I am at 46 wpm letters and I think I should just practice for about 2 hours per day. It seems that if I go with faster than 46 wpm letters I miss too much, so it may be my brain is breaking down the communication into dots and dashes. Any advice would be appreciated.

Tnx my dear !

I was hamming for the past 35 years, and started at 14 on ham-radio, and 15 on CW...
As you can read (and see...) better on QRZ.

Nice to take part of this wonderful world of CW and QRQ, of course, because, my moto is: "If you have to do something - do well" - Why CW at 15 wpm ? (hi)

See also the "MorseRunner Scores" page at www.dxatlas.com, with my other call: PV5X, in some contests...

Many thanks for the welcome in the QRQcw, I'm very honoured.
Still need to learn a bit how-to here.
I hope to meet with all of you on the radiowaves,
