ETH067 – I Think I Have The PSK31 Bug Thanks to Ian Kahn, KM4IK

Everything Ham Radio Podcast Logo - PSK31

Over the past 67 episodes of my podcast, there has been a couple episodes that have really peaked my interest and kind of lit a fire under me to do whatever that topic is myself. Things like APRS back in episode 6, and Broadband Hamnet in episode 29. However, neither of those got me back onto HF. My HF rig has basically gone unused for close to seven years or so and has been in a box for the last three years!!

I honestly have never been big on voice communications on HF. All of the times that I have operated on HF has either been at home calling CQ or looking for someone else calling it or during things like Field Day. At home I rarely got anyone to answer my CQ call; I think I was getting out. During field day it was, basically the exchange and on to the next contact. Neither of these things were very fun to me.

Digital modes, especially thing like PSK31, seem to be right up my alley! So I decided to look for someone that knew something about it, that I could learn from. I finally found Ian Kahn, KM4IK and he agreed to come onto my show and talk to me about it. We had a great conversation and I learned a lot. If you are interested in learning about PSK31, head over to the show notes of the episode, you can listen right on the page, or you can search for Everything Ham Radio on the major podcast directories.

I heard a loud bang!


Oliver likes the other use for the antenna cover
The inside looked great
Over this past weekend I was not able to get out and about with KX3 and CHA P Loop for portable ops as the weather was not very co-operative. I decided to throw the switch on the K3 at home instead, I really did not find too much on the bands. My antenna as I have mentioned in the past is the MFJ 1788 Mag loop. For me to get on the radio the antenna has to be moved to the centre of the balcony and a feedline brought out to it. This is only a 2 minute job to accomplish and the plan most of the time is when I am done to remove the coax and store the antenna back in the corner of the balcony. Now and then I leave it where it is after setup as I may want to use it later. On Saturday I left the antenna in the “operation position” overnight. I woke up at about 3:30 AM to some very loud and strong winds, I thought I should go and get the antenna and put it to the side in its stored position. Then as that thought was leaving me I heard BANG!!! The wind had blown the Loop over and it hit with a very loud bang. I went out right away and up righted the antenna removed the coax and placed the antenna off the side.  Later in the morning I brought the antenna in to inspect it for damage. The outside looked good but it was the antenna tuning capacitor and circuitry end of the antenna that made the loud contact with the concrete floor. I removed the covers and was pleased to find no damage had been done. I then tested the antenna and all was good. Lesson learned, it only takes to minutes to put it to the side and bring it out again. This is worth the time as opposed to spending HUGE money on a new antenna or getting it repaired.  With taking the covers off it allowed me to also do my annual inspection of the antenna as well.

Books

Books.  I love books.  Books and reading are a love that was passed down to me from my Mom. When my sister and I were little kids, my Mom would "treat" us with a trip to the local public library. We would bring home stacks of books to read, and I loved every minute of it. A trip to the library, or even better - the book store, was always enthusiastically welcomed.

That habit stayed with me all my life. When I first became interested in Amateur Radio as a teenager in high school, my "bible" was "The Radio Amateur's Handbook" by Collins and Hertzberg. That book was my constant companion in my teen years and I must have read it, cover to cover, at least a half dozen times. It fueled my wishful dreams of becoming a Ham Radio operator, making contacts with people from all over the world.


I still have that book, and it holds a place of High Honor on my Amateur Radio book shelf.

A few weeks ago, I came home from work to see a rather large package sticking out of my mail box. As I was bringing it into the house, I noticed it was from Schiffer Publishing.  I thought that this was kind of odd, as I hadn't ordered anything from Schiffer. After dinner, I opened the package to find a most wonderful book entitled "Compendium Of Automatic Morse Code".  I couldn't believe my eyes! The book was sent for me to look over and to offer a review.  It is a wonderful piece of work by Ed Goss N3CW.  The amount of work and detail that he put into his book is phenomenal.


Granted, this is a niche book. Not every Amateur Radio operator will gravitate towards an edition like this. If you have a love for Morse Code and for the keyers, paddles and other devices that produce it, then this book is for you.

It is exhaustive in its content and detail and everything about this book screams "quality". From its size, 9 X 11 inches, to the feel of the heavy stock of the pages, to the rich and highly detailed color photography, everything about this book says, "Coffee Table Book for Ham Radio".



The table of contents includes chapters on

Chapter 1: An Overview of Telegraphy and Early Keys - History
Chapter 2 - Code Readers, Oscillators and Morse Trainers
Chapter 3 - The Electronic Keyer
Chapter 4 - The Single-Lever Paddle (Without a doubt, my favorite chapter!)
Chapter 5 - The Dual-Lever Paddle
Chapter 6 - Portable/Miniature/QRP Paddles (My second favorite chapter!)
Chapter 7: Commemorative Paddles
Chapter 8 - Combination Key and Paddles
Chapter 9 - Convertible Paddles and Paddle Modifications
Chapter 10 - Automatic Mechanical Keys
Chapter 11 - The Elements of Paddle Design
Chapter 12 - Paddle Adjustment and Maintenance
Chapter 14 - Telegraph Machines, Keyboard Keyers and Terminals
Chapter 15 - Computer Interfacing and the Internet

And various appendices and a bibliography as well as a list of recommended reading.

Pretty exhaustive, eh?  If you're thinking,"Well really, how much is there to write about on this subject?"  I'll answer that question by saying, "Over 300 pages, as a matter of fact!"

It's not hard to tell that writing this book was a labor of love for N3CW.  It's one of the best if not THE BEST book to come down the pike on the subject.  It has earned an honored place on my book shelf, right next to my beloved Hertzberg and Collins. However, I can tell you that it doesn't stay on the shelf for long. It has been in my hands a lot and will be for a long time to come.

I would highly recommend adding the "Compendium of Automatic Morse Code" to your Amateur Radio library if you're as much as a devotee of CW operating as I am. I can see this book as a golden answer to that age old question that every Ham gets asked every now and then ....... "Honey, is there any Ham stuff that you'd like for your birthday? Or Christmas, or Hanukkah, etc, etc, etc.

Thanks to Ed N3CW and Schiffer Publishing for sending me a copy!  It was a very pleasant surprise and is appreciated more deeply than you will ever know.

The May ‘Bug Roundup’

Vibroplex "Blue Racer"



Ever since earning my ticket as a teenager back in '63, almost all of my on-air activity has been focused on CW ... I've always loved it.




For my first year on-the-air, I used a nice brass hand key purchased locally for just a few dollars but once I had mastered that and I was just unable to send any faster with it, I purchased a Vibroplex 'Original', for, if memory serves me correct, around $40. I used it exclusively until building a homebrew memory keyer in the mid-70's and the Vibroplex saw little service for several years.

The Vibroplex 'Original'
Back when I first got on the air there were very few amateurs using keyers. Most used bugs and the remainder used the brass hand pumps. It was very easy to tune across the band and identify any of the locals just by the sound of their fist ... like snowflakes, no two were the same. The same went for most stations that were very active. DX or otherwise, one could usually tell who it was long before the callsigns were heard.
So much has changed now with the almost exclusive use of electronic keyers and everyone pretty much sounds the same, which is rather a pity I think.

Once my interest in building vintage-style vacuum-tube transmitters evolved, my interest in bugs was reactivated and over the years I have purchased a few more.

I'll do anything I can to promote and encourage the use of CW and especially hand-generated CW. That's why I was excited to read a recent e-mail from W6SFM, posted to several lists that I read, announcing the Bug Roundup!
 
The Samuel F. Morse Amateur Radio Club, a Sacramento, California based CW enthusiast club wanted a special time to bring bug operators together on the air. In the same spirit as ARRL's Straight Key Night, participants are encouraged to make simple, conversational, “chewing-the-fat”, "Rag Chew" QSOs using their bug type key. This is an opportunity to exercise, share and exhibit your personalized fist. This is NOT a contest. Simply Call "CQ BR" so folks know you are a Bug Roundup Participant. Grab that bug, clean those contacts, and let’er fly! Let’s hear that “Banana Boat / Lake Erie Swing" or that commercial KPH/WCC quality fist.

Reserve the day! Saturday May 20th - Sunday May 21st, 2017
7:00 AM to 7:00 AM Pacific Time (LOCAL)
1400 UTC through 1400 UTC

For more information, to register your station and key for participation, and to help assist in spotting, potentially increasing QSOs, an On-line chat window link can be found near the bottom of Bug Roundup home page located at http://www.w6sfm.com/Bug_Roundup.html We hope to hear you all on the air!

It looks like a fun event and might make another good reason to fire-up your old boatanchors on CW once again. It looks like you can keep track of activity and possibly set up skeds via their chat-window page during the BR.

In any event, my biggest decision will be to choose which bug to use as I have five at last count. I think I'll be brave and try the Blue Racer but will probably have to dampen it down a bit as they are really quite fast.
