VE6BLD’s solar pop can heater to warm your shack from the sun.

In 2014 I found a video on you tube of a man in Newfoundland who had built a solar pop can heater. I decided I would build one for my big shop in the back of my large town lot. There is a south facing wall to install it on a foot away from the wall for safety reasons as it can produce 80 -90 degree C!  I had an old double pane window in the shop that was about 3 by 7 feet. So the project began. I also had the aluminum frame from a score clock which had been removed from a school gym which turned out to be the perfect depth to fill with rows of pop cans after being insulated with 2 inch styrofoam. The metal frame also had a perfect indentation on the front to install the double pane window. See the pictures in the link below for how I  built  this pop can heater. I used a small squirrel cage fan on the inlet in the garage and another one on the outlet in the garage. There is a temperature sensor at the top of the outlet pipe connected to an adjustable digital temperature control ($8.00 on ebay). I can set any temperature to turn on the fans and I can also adjust the differential to turn off. As soon as the sun comes up and shines on the heater  it  will quickly come to the set temperature I programed of 32 C. The heater was tested to  produce up to +180 degrees F  (+80 degrees C) before I installed the fans. This is a good reason to have 2 fans so it will not melt the heater if one fan quits! Today Nov 11, 2020 the sun was very low (temperature – 12 degrees all day) but the heater quickly rose to +32 C and the thermostat turned the fans on. The heater produced a steady +18 C temp into the garage all day until there was no more sun shining on it. ! Darn nice free solar heat.

VE6BLD multi-coax junction box on my tower

I have just completed building and installing a multi-coax junction box on my tower. I have 9 coaxes coming down the tower and feeding through a 4 inch pvc conduit to the basement. Every time a thunderstorm approached I would have to go behind my operating desk in the shack and disconnect them all. Two of the lines are 7/8 inch hardline with 1/4 inch solid core center conductor. Any lightning strike would have a direct path to the shack- not great!! I had an old aluminum weather proof  box which was used for a chart recorder in a town pump house. Please see the pictures for the construction and finished product. There is also another WP box three feet away to connect the coaxes from the house to a grounding bar during bad weather. The red banana plugs ground the disconnected  coax coming down the tower after they are disconnected. This way there is no path for the lightning to enter the house through the coaxes.

CAARC Participation in 2020 ARRL Field Day

Paul VA6MPM has agreed to co-chair distribution of information for CAARC members’  (and any other interested amateur’s) entries in the ARRL Field Day.

We encourage your participation in the 2020 ARRL Field Day on June 27 and 28, and your submission of your individual station score to the ARRL. The 24 hours of on-air operations start at 1800Z June 27. You may operate for any convenient part of that period.

We are going to publish what we hope are bite-sized chunks about participating in Field DayThe official ARRL Classes for one or two participants are (from easiest to hardest), choose one:

  1. Home station using only one of your own call signs (Class D). Another licenced household member may also use this station equipment with only one of their own call signs for a separate entry. Class D stations may not count contacts made with other Class D stations. Using emergency power for a home station changes your class to Class E and allows you to claim a bonus and also allows contacts with any Field Day Station to be counted.
  1. Vehicular Mobile (Class C): Stations in vehicles capable of operating while in motion and normally operated in this manner. Normally used by one operator with his own call sign.
  1. Small group portable (Class B) set up and operated by no more than two persons. This can be your regular equipment set up so as to operate from your back yard, and I believe, your garage if it is not your regular operating position. A variant is Class B – Battery, in which All contacts must be made using an output power of 5 Watts or less and the power source must be something other than commercial mains or motor-driven generator. Set-up must start later than 0000 UTC on the Friday (Thursday afternoon or evening local time) preceding the Field Day period. Set up your station up with an effort of a total of 24 hours or less.

In the QST Field Day results each class is listed in in its own category, so in essence, you will compete with similar stations.

We will make further posts, about:

  1. Which QSOs can be counted and what you have to record for each QSO,
  2. Point score for each type of QSO
  3. Multipliers and bonuses
  4. Reporting your score

Background, official rules, and many hints can be found at http://www.arrl.org/files/file/Field-Day/2020/2020%20Field%20Day%20Packet(1).pdf .
