The need for speed in CW

CW QSO speed statistics... 

As I continue on my Morse Code Journey I have been using a desktop application called Morse News to work on my code comprehension of natural language sentences for ragchew training. I set the program to send at speeds higher than I can copy to stretch me.  Presently I have it set at 26wpm character speed and 23wpm Code speed.  I can usually figure out what the news story is talking about but I miss a lot of the specifics.



I was a kid in the 1970s when Speed Racer was a popular cartoon

The need for speed

Currently I'm OK working up to 20wpm qsos as long as the other station has good spacing.  Sometimes I lose the thread or the specifics in a ragchew at 20wpm and I just ask them PSE AGN? 

In sprints I can copy a callsign sent at 25wpm to 30wpm if I hear it a few times but that's no good for real contests where you need to catch that call sent at 30-40wpm sent the first time.  My friend AA4XX has asked me to help him in multi-op contests but I know he is sending around 30wpm and I just can't hang there at this stage in my Morse Code journey.

Statistics show 25wpm is the magic number

So it got me to wondering what was the actual "average" qso speed.  I downloaded days of raw data from Reverse Beacon Network.  RBN collects the call sign, the SNR and the SPEED.  The raw files contained between 40 to 50 thousand CW CQ calls logged each day after I filtered out other modes.

The average speed from RBN CW logs worked out to exactly 25wpm.  The standard deviation was 5.34wpm which would mean most of the time you would expect to work stations between 20wpm and 30wpm.  That seems reasonable and matches what I seem to hear on air.  These numbers are from the CQ calls themselves and are only measuring character spacing speed so the code spacing is likely a bit lower in most cases and for ragchews is likely averaging 2 to 5 wpm lower than the actual sent character speed.  Since I am not much interested in serious contesting at this stage in my hobby going over 30wpm isn't on my radar.  

So based on those calculated CW speed statistics from RBN data if I can reach the point where I am comfortable in a 25wpm ragchew I should be content (for a while)

That's all for now.

So lower your power and raise your speed.... err expectations

One step closer to being a ham techie!


 Now that I can use one Signalink USB unit on either my Elecraft K3 or KX3 I thought it was now due time to investigate operating my rigs remote from my laptop using my router. I have read many ham who do this  so it’s not anything new…BUT….for me this is cutting edge and can be “kinda fun” to get it up and running.  I can across software called Teamviewerwhich allows you to remotely access your PC from another PC. Once logged on and a connection is made you have (on your remote PC) a mirror image of your home PC. You have the same control over your home PC as if you were sitting in front of it. The software allows you to access your Windows PC via a Mac and so on. This Windows/Mac cross over was great for me as my home PC is Windows and the laptop is a Macbook Pro. I set out to download and install the software on my Windows PC. It went very smooth and error free, I then installed it on my Macbook pro laptop and all went well until I started the program. The program just
would not start it just got hung up and I had to do a force shutdown. I tried a few things but just could not get the program to run. I then installed it on my wife’s Macbook pro laptop and it operated without
a hitch! The only thing I can figure is my Macbook is a bit older and may not be up to the task. I was on the internet to see if I could see what the issue might be but could not find anything. I am going to email the company and see what their input is. On the weekend I was not interested in troubleshooting or emailing for an answer I just wanted to get the program up and running. With the program installed on both PC’s and it was time to make the link. It is very straight forward to do, you open the program on each PC. You are given a 9 digit ID number on each PC and since I want to use my laptop to control my main PC on my laptop I enter the 9 digit ID number from my main PC and press “connect to partner”. I then enter a password (setup during program install) and in no time I have full control of
My remote PC operation
my main PC from my laptop. Note: if you want to have control of your laptop from your main PC justenter on your main PC the 9 digit ID number shown on your laptop and press “connect to partner” along with the password. After using this program several times I can honestly say it works flawlessly and very smooth. I was able to open Win4k3suite and WSJT-X and make contacts with JT-65 from my laptop. There was absolutely no latency issues, lockup or programs refusing to operate or open. One great piece of news is if you use Teamviewer for personal use the program is FREE!! If any of my readers has ever wanted to toy with remote desktop operation or you are using a program that has issue give Teamviewer a go!

‘Ham Talk LIVE!’ weekly call-in show debuts Thursday, February 18

neil-rapp-wb9vpgNeil Rapp, WB9VPG, is taking to the Internet airwaves Thursday, February 18th at 9:00 pm Eastern (02:00 UTC) with a brand new live call-in podcast. Ham Talk LIVE! will feature general interest ham radio topics and special guests with a wide range of ham radio expertise.

Unlike traditional ham radio podcasts, Rapp says he hopes to create something a little different. “I really look forward to just doing some open line shows,” he says. “I want it to be a conversation and just talk about happenings more than just disseminating information. We already have people doing a great job with that, and I enjoy watching and listening to them.”

Thursday night’s episode will discuss DXing and contesting and will feature well-known DXer Dr. Scott Wright, KØMD. Next week he’ll host popular Amateur Radio Newsline anchor Don Wilbanks, AE5DW.

To tune into the show, you can visit HamTalkLive.com. To participate, listeners can either call Skype username ‘hamtalklive’ or dial (812) 638-4261. “I don’t have a call screener. Once I answer they will be on immediately so I won’t answer until I’m ready for the caller,” Rapp says.

The show will last 30 minutes each week. If listeners miss the live show, a downloadable podcast will be available on iTunes, Spreaker, and possibly other outlets soon after each broadcast.

If the format works out well, he may extend the show longer than the allotted thirty minutes. “If people listen, I’ll definitely extend the time,” he says.

Rapp is a high school chemistry teacher and sponsors the ham radio club at his school. He was first licensed in 1976 at the age of five. He is the recipient of the 2014 Indiana Radio Club Council Amateur of the Year award, the 2003 Indiana Radio Club Council Technical Excellence Award, and the 2004 ARRL Professional Educator of the Year award.

Learning CW – The Beginning

I have decided to learn CW. Why? Because I want to, not because I have to.  Yes I am one of those no-code hams!

Most of this blog post is aimed at newer hams. If someone is thinking about trying to learn CW, I hope this post might help motivate them to go for it and give it a try.

Since I became a more active ham a couple years ago, from a non-active ham, I have thought it would be nice to have a very small portable battery powered radio, and easy & quick to deploy antenna and make some QSO’s when and where I can.

The next question, once I decided to learn CW, was how to learn CW? I know in the past, people used to use cassette tapes, learning at 5 wpm (words per minute). I looked online and found that the “tapes” can still be purchased, but now they are on CD instead of tapes. From the reviews that I have read, the content has not been updated but simply copied on to CD format. So it’s the same lessons that existed in the 60’s, 70’s, 80, etc, just in a little newer delivery format. My goal isn’t 5 wpm. It’s higher. More like the 20 wpm range someday. That then leads to some “newer” methods of learning. The “Koch” method is very popular. It starts with two characters, sent at 20 wpm but with more space between the characters, making the effective overall speed slower but still with faster character speed. The key is learning characters at a faster speed, introducing another letter when you learn the first two. You keep adding letters until you eventually have them all learned. There are many web sites and programs that use this and other methods. There are also a lot of phone apps that people use to learn. A friend of mine learned CW using these apps, and I sat with him on Field Day in 2013 as he worked without a microphone, only CW. He didn’t even bring his microphone to Field Day! He now works CW almost exclusively.

2016-02-15 17.54.27

After further research I came across The CW Operators Club web page, http://www.cwops.org.  I found that they have a CW Academy with 3 different levels. Level I is for beginners with no CW experience and Levels II & III are more advanced working on increasing speed and other things. I decided to enroll in their Level I beginner class. I signed up on their web site and weeks later, I was confined for the Level I class that started in January ’16, a few weeks ago. I am now 5 weeks through an 8 week class. The class meets twice a week, using Skype. There are five students in my class, which is lead by an experienced instructor. Homework consists of using a web based CW training program, for receiving practice. Assuming you have a key/paddle or something to send with, there are sending exercises as well.  The curriculum introduces the letters, much like the Koch method, at a 20 wpm pace, but in a different order than the standard Koch trainers. The first session consisted of four letters, and words using those four letters. If you would like more information their web site is: http://www.cwops.org

Is it working? So far it is working. Five weeks into the class, I now know the whole alphabet, the numbers 0-9 and a few punctuation characters. I say “know” them, but I am not very good at receiving yet. I miss a lot of characters when I try to listen so a real QSO on the air. Like learning anything like another language, it’s going to take some practice to get better at listening in real time. I have recorded a couple QSO’s from a websdr.org station and when I repeat it multiple times, I can figure it all out. Considering 5 weeks ago I didn’t know a single letter, I am making progress.

I’ll continue attending class, and practicing. I’ll post again later when I make some more progress and someday pretty soon, I’ll get in the air and attempt a real QSO!

Until then    – – . . .   . . . – –

PS   “- – . . .   . . . – -”  is morse code for “73” in case you wondered!

Trans-Canada On 630m

courtesy: http://www.bing.com/mapspreview
Under most circumstances and on most bands, a contact between VE7 and VE3 would not be considered 'exciting' or 'challenging' ... but Saturday night's CW QSO between myself and Mitch, VE3OT in London, Ontario, met both of these criteria, as it was done on our new 630m amateur band on 475.0 kHz. As such, it represents the first-ever interprovincial contact as well as the furthest contact (2031 miles) between two Canadian stations on the 630m band. As usual, there's more to the story ...

Both Mitch and myself had been alerted to the excellent propagation earlier in the week, when VE3OT's CW beacon had reached S9 levels here for several hours on two consecutive nights ... but any late-night QSO attempts would have to wait until the weekend, when having to get up in the middle of the night would not conflict with Mitch's workweek schedule.

Our first attempt, late on Friday night and 3A.M. for Mitch, found that conditions had deteriorated from midweek's enhanced propagation and the low signal levels, combined with some unseasonal lightning noise, resulted in rescheduling for another shot on Saturday.

Late Saturday night found the band much quieter and propagation much improved, but not as good as it had been earlier in the week ... somehow Murphy always seems to have a hand in pre-planned events, and it's never a helpful one. Mitch's beacon signal was readable here but had a deep ten-minute fade cycle with a short-lived peak before fading out to nothing.

VE3OT at his loop's loading coil
Hoping to take advantage of one of the peaks, we began short two-by-two calls from both sides shortly after 0700Z. I eventually heard Mitch fade up and sending a '339' signal report but my response and '559' signal report to him went unanswered as he had faded away again. I continued the short calls, along with my signal report to him and on the next peak heard him responding with 'RRR and 'QSL'! This time his signal continued to build and we had several short exchanges, with Mitch upgrading my RST now to '549' and with me advising of his stronger '569' signal. As the fade cycle took its grip once again, we exchanged our '73's', 'TU's' and 'SK dit-dit's', while we still had the opportunity ... I can't speak for Mitch, but for me it was a truly exciting contact and one I'll not soon forget.

LF / MF station at VE3OT
I'm sure the opportunity to work again will present itself fairly regularly as we both know that Saturday's conditions were not the best. It will be interesting to try again when signal strengths reach the levels previously heard during the week.

For those of you that worked VE3OT during the recent 630m crossband event, Mitch has put together a very special QSL card!


As the solar cycle winds down, the 'good' nights will happen more often, as will the truly 'great' nights. Hopefully there will be more Canadians on the band to take advantage of what lies ahead.

Hopefully the U.S.A. will soon have the band as well, which will really spark nightly activity. What is really needed right now is more Canadian activity, especially in the western provinces, where nightly CW contacts could be readily made. Time to reach for the solder iron! There are several VE7's, and one VE3, waiting and wanting to work you!

‘QRP School’ shows how to have big fun with a small signal

qrp-school-n4ccbEvery amateur radio operator is attracted to different aspects of our diverse hobby. For Cliff Batson, N4CCB, of Nashville, Tennessee, it’s QRP — making radio contacts with 5-watts or less.

“I’m not an expert, but I have quite a bit of passion and enthusiasm for QRP. There’s just something magical about being able to make contacts using less power than a nightlight,” says Batson.

Batson started a video blog called QRP School late last summer and recently added his twentieth episode. He’s already covered topics like using a deploy-anywhere vertical HF antenna (below), solar power operations, building a computer-to-CW interface, bringing your gear along on vacation, and many more. He says that he hopes to add even more QRP-related videos soon.

“Ham radio is a big hobby, and there’s room for all of us to enjoy whatever we enjoy, while letting others do their own thing,” he says.

If you enjoy QRP or want to learn more, you can visit his site at QRPSchool.com and subscribe to his YouTube channel.
