Having a snake of a time.

 


In retirement, I want to keep my mind sharp, and to do that, I have to challenge myself. My latest adventure is learning Python coding.
A little history about Python coding: the founder, Guido van Rossum, a Dutch programmer, came from the Netherlands. His goal was to birth a code that was easy to read general purpose programming language. Why the name Python and not Rossum, you ask? The name came from Monty Python, and he felt that gave it a light-hearted name. In the Zen of Python, this phrase sums up the code experience: "Simple is better than complex." Oh, and those who code in Python are known as Pythonista's and I am striving to become just that.
So why all of a sudden my interest in coding......well, it has to do with my son Ben, who is a whiz kid at this stuff. Funny story.....Ben went to the University of Toronto and majored in cyber security. He wanted to get into a top tier program and had to have some interviews. He was given a few exams and then called in for an interview. The interview was conducted by the department head, the lead professor and the admin for the program. The main purpose he was called in was because the most complex question and the main question on the exam he left blank. When asked, he told them the question had incorrect coding and he was not going to waste time on it! He was asked to explain, and he did, and was told Thank you for coming in. Ben called me after the interview and told me the story. I could not believe what he did and was about to give him a piece of my mind. Before that could happen, he told me the professor called later in the day and told  he was accepted, no more interviews or exams were required, and they were changing the question as he was correct.
In a phone conversation with Ben, he challenged me to pass some of my time learning Python coding. He said it was very user friendly and it could really help with my ham radio adventure. I took him up on the offer, and now I am in the process of coding to make ham radio at VE9KK a little more automated.  More on how that is coming very soon, as I have already produced some coding that has shocked me and is helping VE9KK's CW contesting station become a “Geek shack”

Whats your thoughts?

  

Possible RF magnet
While doing my annual pc cleaning last month, for some reason, I took special notice of my Wi-Fi SMA antenna connectors on the back of the PC. I have disconnected the Wi-Fi antennas as they are not used and get in the way of the cabling they. In my case, to get connected to the internet, I have a LAN cable from the back of the PC that goes to the hallway to a TP Link Wi-Fi extender. I find I get a better signal this way as opposed to using the Wi-Fi antennas on the rear of the PC.

Needed connectors
 Back to the Wi-Fi connectors on the rear of the PC, as I was cleaning, a thought came to me that these open Wi-Fi connectors could be a nice RF magnet. In the past I have issues with RF getting into the PC and to eliminate as much as I could is a bonus. I did have a few 50 ohm SMA male connectors and I thought with that I would be good to go. On closer inspection and a frustrating experience trying to get the 50 ohm to connect to the PC, I found the SMA connector on the PC was a male and the 50 ohm connector is also a male connector. This had to be purchased, and it's called RP-SMA.Once they came in, the connection went very smoothly. So what are your thoughts on this, most if not all PCs have Wi-Fi antenna options and if you're not using it and prefer LAN connections should these antenna connections be terminated with 50 ohm terminators?

Connected and ready to go.

ARRL CW Sweepstakes contest

Normal contesting CW keyboard layout. 

 
This weekend is the running of the ARRL Sweepstakes CW contest. Last year was my first year participating in this contest. I have avoided this contest as I felt the exchange was a bit complicated. Once I dipped my toes into this contest last year, I realized it wasn't all that bad and was actually very challenging for me as a CW op. Before we go over what is sent in the exchange, let's go over the finer details of the exchange. 
 The exchange consists of: 
Serial number starting at 1 
 Precedence (A for single of low power, B for single op high power and so on) 
Your call sign is now sent 
 
Check (The last 2 digits of the year you were licensed)  
Section (For me it's NB for New Brunswick) 
 
ARRL Sweepstakes layout 

Therefore my exchange for example would be as follows.... 
1 A VE9KK 89 NB 
My next contact would be 
2 A VE9KK 89 NB 
It's not your same old some old exchange and it really keeps you on your toes as the exchanges are being sent to you. During the contest, you may be asked to send only a certain part of the exchange back to the other station, such as NR, CHECK, or PREC, and so on. For this contest, I find remapping my keyboard the easiest way to operate in this contest. I have included a picture of my "normal" looking contest keyboard and then the revised ARRL Sweepstakes keyboard. In this contest, until I get the flow of things, I will be search and pounce and thus the green keys are the ones I will use most, if not all, the time. It seems funny to some to add the green key shading, but for me in the heat of battle, seeing "CHK" or CH? can get confusing. Running search and pounce, I only pay attention to the green keys. Over top of my "normal" contesting keys, I placed the sticky part of the Post-it notes to cover what is usually there. Again, to leave it would only serve to confuse and frustrate me. When the contest is done, the post it note is peeled off.
