Back home a week later

It was a great time being back in Ottawa, visiting with friends from my old neighborhood and also spoiling my Daughters two cats.

However on the “Radio side” of things …. not so good

The plans were that I would be able (weather permitting) continue to control my hour on the Trans Provincial Net while away. It seemed that “Mother Nature” had different ideas. Most days rain or the threat of rain kept me from heading over to the park.

Above pic showing where the park was and the route I took

As I mentioned in a previous post…. there was a local (non-POTA) park within walking distance to operate from. It was a local sports field and had some bleachers for when the crowds came for Junior Soccer/Football and or Rugby…

Below pic showing how I set up at the park

Although the operating position was excellent there was NO PROTECTION from the elements which in my case meant rain.

I was able to wrap my MFJ mast to one of the bleachers and stretch the end of the EFHW antenna to the other bleacher and it did work like a charm. Signal reports were great considering I was running 50w into the antenna

So for 1 out of a potential 5 operating days it was fun and dry. Walking home with the gear safely packed in the backpack “Mother Nature” paid a short visit.

I also managed to activate CA1515 and CA1516 using my Xiegu X5105 along with a 29 foot wire (supported by the same mast mentioned earlier) with a 9:1 unun, a 17 foot counterpoise with a choke on the radio end of the coax. Jose VA3PCJ was nice enough to offer me a ride there and back. I activated the parks using SSB and VA3PCJ activated the same parks using CW and his KX3.

For Jose’s version of the park activation click HERE

I am expecting to be returning to Ottawa in Mid-January 2025 for another visit with my GrandKits and like last years winter visit there will be a car to keep me warm and dry.

MassJam and the 2023 Head of the Charles Regatta

19 April 2024 at 03:43

Note: This was supposed to be published in the November issue of The SPARC, the Boston Amateur Radio Club newsletter, however, due to unforeseen circumstances, it was never published, so here it is for the first time in print! 

It was a busy public service month for me. First off was MassJam 2023, the multi-state scout jamboree that is held every five years at the Cape Cod Fairgrounds in Falmouth.

While the communication staff was made up of entirely of hams, the event did not use amateur radio for its operation as obviously, while there are hams in Scouting, not everyone is a ham and therefore, commercial band radio was a must for the event. Using radios provided by DC Rentals (who seem to provide the commercial radios for practically every large event in Boston) MassJam got underway. Net control was a 24/7 operation with shifts scheduled in blocks and food for the net controllers was cooked on site. Despite some hiccups, the event itself was mostly successful, including exodus from the campground was went really well and finished practically on schedule.

After a week and a half off, it was time for the next major public service event, the 2023 Head of the Charles Regatta. I was stationed all 3 days at the Attager (which is Regatta spelled backwards) Row First Aid tent. A ham’s job at the regatta is to be the primary link for the first aid tents to net control and from there to the event’s roving bike teams on commercial radio (again, provided by DC Rentals) and if needed to our public safety partners such as the Massachusetts State Police (who provide their command post for the weekend where a ham is stationed as a link between net control and them), Boston EMS and Cambridge Fire. Joined by a rotating motley crew of hams, including our very own public service chair, Ethan KC1OIP, we made the best of it despite pouring rain on Saturday and cold winds on Sunday.

All in all, a good month of public service. I recommend the Regatta as a good place to start if you’re interested in the public service side of this great hobby. Now to look forward to next year’s public service season with the Boston Marathon!

Vulnerable MOSFETS in NASA's Europa Clipper

18 September 2024 at 10:09

 

Oh man, this is terrible.  Just months before launch of the Europa Clipper mission to Jupiter's satellite, they discovered that some of the MOSFETS in the spacecraft might get fried by the Jovian radiation.  1500 MOSFETS.  Ouch.  Details here:

Multi-Tasking from the Park

By: VA3QV
5 September 2024 at 18:32

Life is great IF you can get everything happening when it should. Today was living of proof of having to improvise and adapt….

Liz (the patient one who tolerates/supports this hobby) had a follow up appointment at the Providence Care Health Facility here in Kingston for 1030 am… At 11am I was supposed to be the Net Control Station for the Trans Provincial Net on 7.100.

This is a conflict and I have to give priority to Liz…. But here was the solution and it worked…

I dropped her off at her appointment for 10:15 and then walked out the back door of the Health Facility and into POTA CA-6003 which is the Great Lakes Waterfront Trail.

In the above graphic the Health Care Facility if the Grey building and the Trail is the thin green line right below it.

I had activated from there before and knew which trees would work with what picnic tables.

And yes I had brought my “Transportable Station” with me….

The FT891 was quickly hooked up to the 20AH battery and my “HomeBrewed” EFHW was strung between the trees… I managed to make a couple of POTA Contacts on 40m before the TPN started up at 11am. (thanks for the 2fer Bill) I managed to wrangle up 9 Checkins to the net which is not too bad as I took the summer off from my regular 11 am shift.

After the net ended I managed a couple of POTA contacts on 20m SSB which made it a successful POTA activation along with keeping up with my obligations to the Net. At 12:15 Liz sent me a text telling me she was finished and to meet her in the coffee shop in the facility. At 12:30 I met her in the coffee shop and we headed back home.

All in all it was a busy but fun start to the day…

Who can tell us more about Lovelock's homebrew shortwave radio?

5 September 2024 at 10:13

"Three years earlier, Lovelock had listened on his homemade shortwave radio in Finchley to the 'beep, beep, beep' transmission of the USSR’s Sputnik, the first satellite that humanity had put into orbit. Now he was playing with the super powers."


A bit of a soap opera, but the radio question is, I think,  interesting.

CuriousMarc Visits Cape Canaveral -- Lots of Space History (and some ham gear)

1 September 2024 at 10:07

I like all the CuriousMarc videos, but I especially liked this one. Marc and company visited some of the very early launch sites and bunkers at Cape Canaveral.  If you thought Apollo tech was crude, take a look back at what they used in Mercury and Gemini.  Wow.  

I spotted two ham radio receivers.   In the first bunker at 10 minutes 28 seconds we see an old National HRO Sixty with the classic HRO dial, much like the one given to me by Armand WA1UQO. (Thanks again Armand!) Note how they attribute one of the early launch disasaters to two diodes in the power supply that shorted due to launch vibration.  I hate it when that happens.  

In the second bunker we see a Hammarlund HQ-140 at 19 minutes 7 seconds.  This was apparently being used as a Frequency Standard (or maybe a time standard?) perhaps receiving WWV at 10 MHz.  I note that the frequency knob shows it set for the AM broadcast band...
