Last week I clicked on a desktop shortcut to open one of my radio programs and the arrow kept spinning and then disappeared and no program opened. I tried some other desktop shortcuts and some worked and some did not. 

Below is the road I travelled down to eventually fix the issue and it turns out that this could happen to any one of us. By outlining the path I followed I hope it helps others out there who may encounter the same issue. 

Before I begin by way of background my setup is as follows:
Win10 home 64bit
 Intel Core i5-10600K CPU @ 4.10GHz  4.10 GHz
RAM 32GB 

My first step was simple and has helped in the past, to restart the PC and give the desktop shortcuts another try. That did not work.
 I then chose one desktop shortcut and it's program to investigate and try to get it working. 

Next, I turned off my Antivirus software (Bitdefender) for a period of 15 minutes and restarted my PC, checking to make sure the Antivirus was still off (it was). I tried the program again and it did not start. 

I then went into Bitdefender antivirus made an exception file for the sample program and restarted but that did not work either.
Next, I started the PC in safe mode and was going to try the programs there but once the PC started the programs I wanted to test were not there. 

I uninstalled the program using Revo uninstaller (great program by the way) I then restarted the PC went to the program's website and downloaded the program again with the antivirus turned off. After restarting the PC I tried the program and it did not work. 

I did not think it was a Windows update as I run a program called Windows Update Blocker (another great program) it blocks all updates until I get the all-clear from the Askwoody site. This is a great site and click on the link to check out lots of great information there. 

It was now time to take things to the next level. I am a firm believer in backing up your PC for the just-in-case moments. The program I use for this is Macrium Reflect and with it, I make a clone and image file of my solid-state C hard drive. The backups are stored on separate internal HDs. One drive for the clone and one for the image. Click on clone or image if you are not sure what they are and you will be taken to a website that explains them. 

I decided to use an image of my C drive from an earlier date when I knew the desktop shortcuts and programs were working. Now you have to remember that anything on your PC after the date of the HD image date will be gone. If your image is from January 30th, 2024 anything on your PC after that date will not be there once you revert to that image. Now I know there is the Microsoft system restore as well but I have never had success with the program. I always get the message "System restore failed to restore to earlier image"
After Macrium Reflect did its magic and I was using an earlier image of my HD all programs were now working fine! So this thought.........
The next day I was on my PC and started the sample problem program and low and behold a spinning arrow and then the program did not start! 

I was doing some nosing around in Bitdefender and turned off the antivirus again, then under protection I turned off Online threat protection and did a restart still had the issue. I then did the same to firewall, ransomware, vulnerability protection and advanced threat protection. It was then I turned on advanced threat protection everything started to work just fine.

I then turned on each protection feature and checked the programs and there were no issues but once advanced threat protection was turned on programs would not start.
Within advanced threat protection in the settings, you had the option to set up exceptions but these exceptions had to include the "exe" program file within the file exception. (I found this out with lots of reading on the internet). As well all exe files from the program have to be included or the program will still be blocked from working.

The Royal Canadian Air Force celebrates 100 years of service and Amateur Radio marks the occasion with special event stations

Surrey, BC – The Royal Canadian Air Force (RCAF) is celebrating 100 years of service this April, marking a significant milestone in Canada’s military history. This centennial event offers a unique opportunity to honour the RCAF’s rich heritage, recognize its dedicated personnel, and generate enthusiasm for its promising future.

Throughout 2024, the RCAF will be showcased in a past, present, and future context, emphasizing its contributions to national safety and security, international peace, and global stability. The RCAF 2024 Team is curating a year-long program that includes international, national, and regional events. These events include the RCAF Run, RCAF Gala, Legends of the Sky, and participation of allied air demonstration teams in Air Shows across Canada. The program also includes initiatives to inspire future generations of Canadians through Science, Technology, Engineering  and Mathematics (STEM) activities.

We're hoping to have all bands and modes worked, including GOTA, POTA, and whatever else you can activate. If you are a VE7 or VA7, you can reserve a time slot. Go to the direct calendar link which is now live at: https://bit.ly/VE7RCAF and look for April 2024. The operating rules are at: https://drive.google.com/file/d/1_fkPdYJ7DDDSLRVGY6822hJ_gd0nEfy6/view?usp=drive_link. Please use your own callsign as the operator, but VE7RCAF as the station callsign for the log.

The VE7RCAF and several other provincial QRZ pages are also active now. QSL cards and awards will be available to commemorate contacts, and special recognition will be provided to those who contact all the RCAF special event stations across Canada during the month.

The RCAF Centennial is more than a celebration; it’s an opportunity to showcase Air Force personnel and their accomplishments, demonstrate air and space power, enhance the reputation of the RCAF, and proudly honour its distinguished history and heritage.

My ham radio pursuits have tended towards the VHF/UHF bands and the 6-meter band (50 MHz) has always been interesting to me. I like to think of 6 meters as a VHF band with some strong HF tendencies. Most of the time, propagation is local, certainly beyond line-of-sight, but also not long distance. When sporadic-e and F2 propagation show up, 6m tries its best to act like an HF band, skipping the signal off the ionosphere.

We call it the magic band because magical propagation occurs just when we least expect it. A more accurate name might be the fickle band because 6 meters provides short periods of random excitement followed by long periods of severe quiet. And that is why we like it so much.

Jim Wilson K5ND recently completed the third edition of the book Magic Band Revealed. Of course, I had to read it and I surely did enjoy this book. Jim hits all of the different operating and propagation modes that hams use on 50 MHz: sporadic-e, F2, TEP, meteor scatter, ionoscatter, etc. The WSJT-X modes have had a huge impact on what’s possible on the band, so Jim provides a good overview of the various options (FT8, FT4, MSK144, Q65). Jim also provides some helpful information on VHF contests and operating as a rover.

The best attribute of the book is that it is primarily written as a first-person account of K5ND’s operating experiences. Reading the book is just like having a friend tell you about what they’ve experienced on the band, along with some great operating tips. Great work, Jim!

The book is available as a free PDF download from Jim’s website or in print version via Amazon.

Well, last weekend I completed my 2nd field day "event" Some don't consider it a contest. I had a blast and can't understand why I have not taken part in this event in the past. This field day was the winter field day, now I am NOT a snow bunny at all so I was at my home station with the classification H and it was only me which made it 1H for the session...event....contest. I enjoy this contest (ops I said it) because max power is 100 watts and lots of folks are operating with minimal setups. This means I have to listen hard and pull some stations out of the noise floor. I operated only CW ( surprise surprise) and the speed is not rocket speed and things are much more laid back! I found the average CW speed in around 22-25wpm and that is fine with me. It gives my ears a break from the 35wpm and up I am used to in contests. The way I look at it any practice at any CW speed is great practice. In this...contest I hone my skills by digging calls out of the noise floor and there are lots of them. So cheers to all who took part in winter field day especially those who braved the snow and cold temps! Looking forward to the summer field day coming soon.
