The Operation Market Garden Special Event Station
Commemorating 80 years
An important stage in the liberation of Western Europe
Operation Market Garden was an Allied military operation during the Second World War fought in the German-occupied Netherlands from 17 to 25 September 1944. Its objective was to create a 103 km salient into German territory with a bridgehead over the Nederrijn (Lower Rhine River), creating an Allied invasion route into northern Germany. This was to be achieved by two sub-operations: seizing nine bridges with combined US and British airborne forces (´Market´) followed by British land forces swiftly following over the bridges (´Garden´).
The airborne operation was undertaken by the First Allied Airborne Army with the land operation by XXX Corps of the British Second Army. The airborne soldiers, numbering more than 41,000, were dropped at sites where they could capture key bridges and hold the terrain until the land forces arrived. The land forces consisted of ten armoured and motorised brigades with a similar number of soldiers. The land forces advanced from the south along a single road surrounded by flood plain on both sides. The plan anticipated that they would cover the 103 km from their start to the bridge across the Rhine in 48 hours. About 100,000 German soldiers were in the vicinity to oppose the allied offensive. It was the largest airborne operation of the war up to that point (Wikipedia ©). Perhaps the most famous, after D-Day, in the history of the Second World War.
As part of Operation Market Garden paratroopers of the Allied forces, such as American, British, Canadian, Polish and Dutch troops, landed in the Nijmegen region on 17 September 1944. The region became a battlefield during Operation Market Garden and most of the inhabitants took refuge in the woods or neighbouring towns. It took more than a week of heavy fighting before parts of the region were temporarily liberated. Many people and military were killed and buildings and bridges were destroyed. At the cost of many young soldiers the important Waal-bridge in Nijmegen was conquered. In our collective mind the entire region was completely liberated in 1944, but this was only for a period of three weeks. There was still hard fighting during the winter and complete liberation was not achieved until may 1945.

Commemorating the RCAF Centennial
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.

Restoring a rusty old tower (revisited)
Like being given a 'free' dog...
A BIG Project!
(from The Communicator - August 2013)
Three years ago I received a free tower and rotator. I’ll write about the rotator in another instalment but I’ve since discovered that some ‘free’ ham gear is like being given a free dog… you have to be aware of the hidden costs.
I had never had a tower but always wanted one. I’d been satisfied with my Carolina Windom, an off-centre fed dipole at 25 feet off the ground, that let me use most HF bands right up to 80m. It served me well, and still does but greater involvement in contesting and the desire to move up to a more directional antenna encouraged me to make the move.
Fortunately I have a wife who is also a ham, though not particularly active, but she knows the thrill I get when working a new country or breaking through a pile-up. She was supportive in my quest. Coincidentally I also had to replace the deck on our 30 year-old house. That provided another incentive to get the project started and find the right location. Our old laundry line was accessible from the deck at a corner of the house. The new deck, with glass panels around it would no longer allow this so the new tower would have to do double-duty as the anchor for the clothesline as well. I decided that it would be a light-duty tower as I didn’t have the space for a full-size tower, and I wanted to keep peace with my neighbours.
I spread the word among my fellow club members that I was looking. Pretty soon an offer came in of five ten-foot sections of light duty tower. I picked them up and it was immediately evident that some work would be needed before they would be safe and usable. Thick rust had eaten though much off the galvanized surface. Several of the cross-member welds had broken and one section was noticeably bent. I knew my wife wouldn’t be pleased if I attempted to place that within view.
Over the next several days I spent time washing down my new acquisition, which had evidently spent time behind someone’s shed, judging by the weeds, caked mud and dead critters in and outside the tubing. I also spent some Internet time researching whether I could revitalize this tower and how to go about it.
My daughter-in-law manages a paint store and was able to provide me with some technical advice on surface preparation and coatings. I knew I would have to paint the sections for my wife to accept them right outside her kitchen window. Colour would also be a factor.
I bought two brass wire wheels and some emery paper and set to work to clean off as much loose rust as I could with my power drill. It worked well and a day later I was done. Based on my Internet findings, and helpful reviews by previous users, I tried three products to tackle the remaining rust. From left to right on the adjoining photo they were Permatex brand ‘Rust Dissolving Gel’, ‘Evapo-Rust’ by Rust-stop Canada, and Rust Check brand ‘Rust Converter’. All were applied according to the provided directions and they performed their intended function. The gel, being thicker, clung to the parts better but was much slower and required a lot of re-coating to keep working. The other two products were thinner and more difficult to keep in place, but they produced faster results. If these were small pieces that could be submerged it would be no contest, but keeping to a short section at a time and using a paint brush to keep the area wet with solution clearly showed the Evapo-Rust product to be the most suitable, and the fastest. It also appears to be the most environmentally friendly of the three, though I wouldn't recommend doing this job on your lawn, as I started to do. Yes, the grass did eventually grow back.
The surface was now free of rust and, after another scrub, was ready for inspection. I looked closely at each crosstie and at every weld. Suspicious ones were marked. Several were obviously cracked or already split. With the assistance of Fred Orsetti VE7IO, the welds were repaired. I was ready for paint!
I would have used an oil based primer and top-coat but my expert advised me against it and she was correct. According to the product sheets for such coatings, it is not recommended that you use an oil based product on galvanized surfaces. The paint will release and peel off after a time—and I didn’t fancy the thought of doing this again in a couple of years. There are special coatings available in a spray can specifically for galvanized metal but they are quite expensive with small coverage, exacerbated by the necessity to get inside and out and into all the nooks and crannies around the welds. I decided a brush was the better applicator for that job.
We, (read-in wife-approval mandatory) decided the least noticeable colour on our wooded lot would be a camouflage green. As a result of my ‘colour-Googling’ I had actually suggested a multi-colour camo paint scheme but that was vetoed as being too ‘military looking’, and so the appropriate latex primer and top-coat were tinted. It took exactly one litre each of primer and top coat to paint the five sections twice, with extra coatings on the welds. I used an air sprayer on the legs for the final coat.
Next came even tougher work. I had to remove a section of my cement patio to make the appropriate foundation and dig a big hole. There were brackets available that could be surface mounted but I’m a ‘belt and suspenders’ kind of guy and I wanted this thing in a block of concrete. If guys are not used, the tower manufacturer recommends fastening a section to the house as high up as possible, in my case that was just near the top of the 2nd section. I visited my local scrap yard and purchased some heavy-duty angle aluminium by the pound. I cut pieces to make an equilateral triangle and bolted one to the top plate of the house, running two arms to adjacent tower legs where they were secured by U-bolts. It’s steady as a rock. I used stainless steel hardware for all the section to section connectors in case I ever want (or have to) take it apart. That time is approaching as I have completed a rebuild of a rotator and HF Yagi that will go up in the spring.
It has now been two years plus and the tower shows no signs of either rust or paint failure. It was a lot of effort but I’m pleased I did it. Even with my Carolina Windom centred at the top of the tower, much higher than before, I’m getting much more activity across all the bands.
The sections above the roof blend in nicely with the trees. The final touch was to place flower baskets on the rungs at each level. We now refer to it as the ‘Tower of Flower’ and surprise… the neighbours even say it looks good.

Working POTA: A beginner’s guide and video
SARC in the park!
We had an interesting workshop on Saturday, September 16, 2023. 'SARC in the Park' was a presentation by Dmitry VA7DVO for our members interested in POTA activations. You will find more about getting started in POTA at their website, and in our free digital magazine 'The Communicator'.
With an easy to build and inexpensive segmented 5-band wire dipole antenna, we made several of the 17m SSB POTA contacts shown in this video, including Switzerland, Italy and with a mobile station in Northern England.
The antenna plan is at: https://bit.ly/SARC23Sep-Oct on page 45.
