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?

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.
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,

Bob, I0QM
Thanks for the welcome. I learned of this resource from Bob Carr, W5UX.
Although I'm a member of QRPARCI, I've never actually joined the local QRP society. Perhaps I should someday. My son (AA0BP) and I have participated in some of their Field Day events, and one of their members (N0TN) is a good friend who administered the Novice License exam to my son back in 1983.
With regard to the headphones, they are a recent purchase, so I've only worn them during cool weather! They do a good job of attenuating unwanted sounds from the nearby kitchen, where my wife often has music playing from a CD or radio. I also have a pair of much cheaper headphones (MFJ-392B) that I like a lot because they have individual volume controls for each ear-- I seem to hear slightly better in my left ear.
Hi, Chuck. Thanks very much for the welcome. I will greatly appreciate any advice or tips you or any other QRQ veterans may be willing to pass along. Currently, I'm trying to listen to 40 wpm ARRL code practice mp3's every day . . . just a little beyond my comfortable receiving speed. I keep wondering if "overload" works better than small incremental increases in speed. 73. Rene
Thanks, Chuck. I have found an application to control the speed of the ICW recordings. It works with iTunes on my MAC. The ap is called TRANSCRIBE! and a search for it will find the download spot.
Chuck, thanks for the welcome. Yes, I love straight keys (not very QRQ - but they are nice!) I also use a Vibroplex and a Bencher By-1 with a Logikey K-5 keyer. I came across the web site during a Google of QRQ and find it very interesting.
Hi Chuck , Nice to meet you . I wasn't aware of this page until yesterday . Very good information .
Yes I do enjoy part 15 a great deal . My main station is on the LowFER band on 185.298.25 kHz. , running 1 watt input and QRSS60 . I mainly just run it in the winter , but receive regular daily captures out to 1500 miles at night and up to 300-400 miles during the daylight hours . Antenna is a #14 nickel plated wire , run vertical , 42 foot , with a 5 foot diameter top hat . No fancy ground system , just 3 utility company 8 foot used copper plated ground rods all bonded together .
Waiting for an order of a few capacitors to finish up a 30 meter and a separate 40 meter QRP transceiver that I have spent the past few days building .
Looking forward to being more active on QRP once they are completed , hopefully later in the week .
I have never tried CW over the net , so I am going to lurk around for a while and see if I can get the hang of it . Sounds like fun .
I took the old cushioned stereo headphones and swapped the wires on one of the speakers for positive to negative and then wired the plug to monorol.
I belived it gives me a better shot at copying weaker signals, especially because my hearing has been damaged and I have lost most of the higher frequencies. Then again, it may all be in my head, hihi
Many thanks for your kind welcome, Chuck. Yes, the Flex 5000 is much better than the SDR1000 on CW. I would say that the QSK is just about on par with the Elecraft K2.
Was able to follow the video to modify RufzXP to give the 126 common words.
It's strange- my copying speed seems highest when I first start. When I I do additional sessions on the same sitting, it seem to decrease. So far, my highest score is up to 42wpm. But I fear that doesn't last more than 1 or 2 words.
My Mercury is #13. I have had it for over 30 years!! Of all the paddles I have used, since 1960, it is by far my favorite. The Ham Gadgets MK-1 is a very compact keyer with paddle and keyboard inputs. It is a very versatile unit. Firmware upgrades are introduced via thumb drive to the usb port. N0XAS, the MK-1 designer, is always QRV for new ideas to add to the keyer.
Thanks for the welcome, and I must say I am really impressed with what you've done here with QRQcwnet, we finally have a way to promote solidarity among QRQ operators and those who strive to improve their CW speed. I was pleasantly surprised when Bob (W5UX) pointed me in the direction of this site...it was great to know that most everyone I talked to back around 2003-2004 are still active on the bands (and internet) sending QRQ cw. 73 and talk to you soon!
Before trying to improve my Vibroplex paddle, I looked around to buy a better one such as Begali, Shurr, Kent, Mercury, etc, and found they all or almost use bearings or bushings to very close tolerance but you still stick with some friction and oxydising in the future. they should be gold plated. but will never compete with the Vibroplex jewell pivots.
That is the reason I worked on improving the Vibroplex dual paddles.
The original Vibroplex paddle needed much work to send decent CW over 40 wpm,
And I was tired to clean the silver contacts frequently, so I soldered pieces of gold from an old ring to the four contacts because of two levers and shaped and polished them very nicely.
After, I changed the location of the springs 7/16'' toward the pivots and added bypass wires to each paddle to cancel the spring conductivity. Now I cannot recognise the feel of the paddles at 50 or 60 wpm because I reduced the pressure needed on the paddle of about 50%. I sent the info mod. to Vibroplex and hope they will have a look at it to improve QRQ of their paddles. Bearings or bushings, how close they may be, cannot compete with watch jewell movement!! Hi Hi
Hi Chuck, Thank you very much for your welcoming message and thanks too for approving my application for membership! Hopefully one day I will manage to improve my CW to the point where I could establish contact with you and the QRQcw Group on iCW and really join in on all the fun :-)
Regarding your query about the Graciella, it does not belong to me (K6KX forced me to bring it home two or three years ago to "try out"). The summary of my experience with it is that I like it significantly better than the previous paddles I had used for extensive times: Back to back J-38 for the first 15 years; Bencher; Shurr Profi; Marsh magnetic; G4ZPY VHS;
I bang on paddles and the Graciella is the only one that does not slide around on me. The Profi had "suction cup" feet so with moisture it would stick on a smooth surface; but I could not just slide it to a new position and have it stay put. All others I had to bolt down or otherwise mount in a fixed position until I discovered the "shelf liner" method which works reasonably well I suppose.
I feel like the contact adjustments are also much better than any of the others, but I actually have not messed with them much at all. I am sure I tweaked them when I first used it but have not felt any need to touch them since.
I have never used a single lever paddle and I do not use Iambic (squeeze) keying. I learned on the W9TO where dash would override dot which led me to prefer Type A when I moved to the Curtis chips. But I have recently been thinking perhaps I should try a single lever paddle. There is some possibility my error rate would be improved since it is not possible to overlap paddle closures. The N3ZN ZN-SLR looks like a possiblity but I wonder if my fingers can learn to use a single lever after 50 years.
I tried single lever (a Begali Simplex Mono w/simple spring return) recently and had a pretty hard time adjusting even after a mere 2 years experience with dual lever paddles. My "bread and butter" key has been the Schurr Profi 2 (after upgrading from a BY-1). However, after about 3 weeks practice using only the single lever I found I was approaching my standard level of error, but it seemed to require greater effort than the two lever action. Perhaps that is because I tend to squeeze on a few characters, which gives the impression (perhaps illusion) that it took less effort to send that letter. I would love to try the Begali Sculpture Mono, but that may have to wait a while since I'm considering dipping into savings for a Sculpture standard...hihi.
When double posting is outlawed, only outlaws will double post. I wanted to mention too, that when I get a good method of keying a nice sinusoidal tone into my sound card, I want to wire up the contacts of the Simplex Mono so it can work as a sideswiper...Bob Carr and Ben have been quite influential in making me want to try sidewinding again.
Thanks for the link to the video. I enjoyed seeing the 1937 Mac Key in operation. Having grown up using an electronic keyer, I have a few challenges when switching to a bug. :-)
The key action is smooth and light and the Keyboard outer case allows you to rest the palms of your hands for less fatigue. You don't have to strain to feel comfortable.
I think the QSK-5 is a good purchase.There are NO added timing components between the xcvr and the QSK-5. No hot switching problems and no thumps/clicks in the rx. No problems with or without the SB-220 amp on. It is a true pleasure since it is silent, except for the high voltage created clicks physically from the circuitry inside the case of the QSK-5. You have to listen very closely to even detect the clicks. (NONE IN THE RX).
This is some detail on using the QSK-5 with the TS-930 and the TS-450:
I hook the cw keyline of my keyboard to either rig's key input- I hook Key-2 (QSK-5) to Pin 4 of the REMOTE jack of the TS-930 (amp keying line using the built-in transistor) and on the TS-450 I built up an NPN transistor switch- collector to Key-2 (QSK-5)- the base of the transistor to +12 VDC on tx on the TS-450 REMOTE jack pin 7 with a 10K resistor- base in series- with pin 7, that is- and emitter to chassis ground- Key-1 (QSK-5) directly to chassis ground to enable QSK operation- I can use my station without the QSK-5 in line just by switching the AC front panel toggle switch OFF- you would only do that when testing and tuning your antenna tuner since you may blow the pin diodes with inadvertant high VSWR making tuner adjustments- I hope these comments are helpful and clear- I have quiet QSK with this setup-
One more note- I go from low power to full amplifier power output by simply using a separate toggle switch to close the amp key line- the amp's idling current of around 100 ma does not cause idling current white noise in the receiver that is noticable- if you wanted to get fancy, there is a FET inside the QSK-5 that could be wired in with shielded 2- conductor cable that could be used in the amp's bias circuit to switch the tube bias on and off, if needed but I have not used that circuit yet- the FET switch is the way to go, since idling at 100 ma on the amp's tubes could generate long term heat- (I don't chat for days!) The bias for the FET is timed to follow your keying-
Hello Chuck, the Trimm headsets as you show have a metal disk and two combination magnets/electromagnets the disks resonate and peak the audio and act like an acoustic filter. There are also little tricks that professional marine telegraphers did in emergencies, like put the shallow cup of the headset on the cheek with the top hitting the little bone in front of the ear which is about 1-1/2 inches from the ear. In period of SOS during QRN5 heavy static atmospherics, we would position the Trimm headsets there and adjust the stream of air coming out to attenuate the loud static and just pass the Morse signal. It is a trick that works well also on 80 meters and 160 meters. We would also buy single cords to each headphone so we could monitor two frequencies. Each headphone plugged into a separate receiver. Often we had yet another frequency on speaker watch, but as you know a headphone watch is much more intense if you do it right on a congested frequency like 500 kHz. = 73 de N1EA

The JUNKER straight key is German surplus. It is a fine key but unfortunately the supply of these keys seems to be drying up in the States.
The VIZ Bug is a right-angle model. These keys are all-brass construction; smaller & quieter than Vibroplex bugs. They are made by Tom K4VIZ.

One more note- I go from low power to full amplifier power output by simply using a separate toggle switch to close the amp key line- the amp's idling current of around 100 ma does not cause idling current white noise in the receiver that is noticable- if you wanted to get fancy, there is a FET inside the QSK-5 that could be wired in with shielded 2- conductor cable that could be used in the amp's bias circuit to switch the tube bias on and off, if needed but I have not used that circuit yet- the FET switch is the way to go, since idling at 100 ma on the amp's tubes could generate long term heat- (I don't chat for days!) The bias for the FET is timed to follow your keying-

Hello Chuck, the Trimm headsets as you show have a metal disk and two combination magnets/electromagnets the disks resonate and peak the audio and act like an acoustic filter. There are also little tricks that professional marine telegraphers did in emergencies, like put the shallow cup of the headset on the cheek with the top hitting the little bone in front of the ear which is about 1-1/2 inches from the ear. In period of SOS during QRN5 heavy static atmospherics, we would position the Trimm headsets there and adjust the stream of air coming out to attenuate the loud static and just pass the Morse signal. It is a trick that works well also on 80 meters and 160 meters. We would also buy single cords to each headphone so we could monitor two frequencies. Each headphone plugged into a separate receiver. Often we had yet another frequency on speaker watch, but as you know a headphone watch is much more intense if you do it right on a congested frequency like 500 kHz. = 73 de N1EA
