VE7RLO UHF repeater back on the air!

After unexpectedly going silent a week ago, the VE7RLO UHF (442.525+ PL 100) repeater is back in action.  Myles, VE7FSR and Doug, VA7GPX made a number of trips up and down Mt. Dufferin to bring down, and take back up the repeater, both times in the dark.  One the first trip up one evening, Myles discovered that the fuse had blown on the repeater power supply, and not having brought any tools with him (other than a tiny pocket tool which was all but useless) it meant another trip up to take the repeater out of the rack and bring it down for testing.

After some head scratching and bench testing the best hypothesis was that the stock power amplifier (PA) fan was not running when there was an Allstar connection (such as during the Rainbow Country Net, which is when it died a week ago) which probably led to the PA overheating and blowing the fuse.  A new bracket was fabricated and couple of fans were added that operate all the time, cooling the PA and power supply.  After two days of bench testing showed everything was working fine, and no overheating problems were evident, it was time to take the repeater back up the hill.

Last Friday evening Myles and Doug took the repeater back up to the top, which led to some interesting questions from curious and confused night time dog walkers!

Thanks Doug for your assistance and company on this project!

Updated: KARC Monthly Meeting this Thursday, February 3 at 7:00 PM

The next monthly meeting of the Kamloops Amateur Radio Club will be held on Thursday, February 3, 2022 at 7:00 PM PST.

We are going to do things a bit differently from now on, and will be opening the meeting at 7:00PM so that members have a chance to chat, catch up, share news of their recent exciting DX contacts, etc.  So feel free to sign in a bit early and kibitz with your fellow hams!

We will start the official portion of the meeting at 7:30PM as usual, and this month we are fortunate to have our very own Ralph Adams, VA7VZA to give us a presentation titled:



Ralph tells us that this talk started as a joke over a lunch with Myles, VE7FSR at his favorite restaurant, the Coconut. 

"I was explaining my lack of progress with getting on air on HF and all the ways I kept finding to play with my collection of cheap software defined radios. After about fifteen minutes of me going on, he shut me up by suggesting I do a club talk on the subject. So here it is."

Ralph's presentation will give listeners a quick introduction to SDRs, a quick description of what is meant by inexpensive SDRs, and an introduction to the software available to operate them.  Then Ralph is going to tell us about all the ways he has found to have fun with SDRs, some things that he has tried, and others that he is going to try. You may have already heard about some of these in his last talk on weather-related projects, tracking weather balloons, decoding weather satellite images, etc..

Ralph is going to tell us about more fun SDR projects such as: tracking aircraft using the ADS-B system, recording IQ spectrum for "tuning" through later, surveying and tracking down RFI sources, as panadapters for high-end HF rigs, and amateur radio astronomy projects such as the one we heard about last month from Ken Tapping. With luck we will get to learn about the kiwiSDR network, an amazing resource, especially for those of us who suffer from RFI and HF antenna challenges.

This will be an online meeting so please use this link to join: https://bbb.isurf.ca/b/ada-jnt-mkf

Non-members are welcome to attend, so please feel free to share this information and the meeting link above with anyone you think might be interested.

Follow up to "Taking the Moon's Temperature" by Ken Tapping

As promised at the January meeting, Ken Tapping has followed up with a plethora of information for those of us interested in "backyard" radio astronomy.

Ken tells me that he has sent a highly-eclectic selection of stuff (see attachments by clicking "Read more") that might be of interest to backyard radio astronomers. He has also attached a copy of that solar radio programme paper he spoke about during his presentation, because there might be odds and ends of useful stuff in there.

There are no books on "backyard" radio astronomy that Ken would recommend. However, there are two main-stream radio astronomy books that are loaded with useful information:

  1. Radio Astronomy, by J.D. Kraus. McGraw Hill. The edition Ken has was printed in the 1960's, so the background discussions are not so buried in "clever stuff" that one cannot understand the important information. The one Ken has is the old, regular-sized hardback with a blue cover. Ken looked on the web and learned that the book is still out there for sale.
  2. Solar Radio Astronomy, by MR Kundu - John Wiley - again, 1960's. Lots of stuff here for the solar radio oriented.

Ken noticed an RSGB book titled "Amateur Radio Astronomy", by John Fielding, but he said he knows nothing of its contents, so he cannot recommend it.

Ken also included the website for the Canadian Centre for Experimental Radio Astronomy. There is a lot of backyard radio astronomy information - and more - so please check this out.

If anyone wants to have their email address added to the backyard radio astronomy email list that Ken mentioned, please let Myles know and he will forward your email address to Ken.


Congratulations to Dwight VE7BV!


Congratulations to Dwight Morrow, VE7BV, on receiving his DX Century Club Award under his TG9BBV callsign! 

He tells us that there was some kind of "glitch" in his TG9BBV file with the ARRL and it delayed his receipt of the award.  He has 119 countries worked, and 112 countried confirmed.

Way to go Dwight!

Reminder: KARC Monthly Meeting this Thursday, January 6 at 7:30 PM

Happy New Year to all!

The next monthly meeting of the Kamloops Amateur Radio Club will be held on Thursday, January 6, 2022 at 7:30 PM PST.

We are pleased to announce that Ken Tapping from the Dominion Radio Astrophysical Observatory (DRAO) will be our special guest presenter, and he will be telling us how he takes the temperature of the moon!  He has a really awesome presentation, and I'm sure (like me) you will be amazed at his creativity and astounded at his willingness to stand outside in the cold to get these accurate measurements with home-brew equipment.

This will be an online meeting so please use this link to join: https://bbb.isurf.ca/b/ada-jnt-mkf

Non-members are welcome to attend, so please feel free to share this information and the meeting link above with anyone you think might be interested.

Thank you to Nutech Phoenix!

Thank you to local company Nutech Phoenix and President Bob Dieno for their very kind donation of reconditioned CO2 fire extinguishers for our KARC repeater sites. 

Nutech has been in business for 26 years and they have supported many local non-profit organizations by donating fire fighting equipment, service, or parts to keep those organizations and their volunteers safe and to help keep their costs down.

Nutech Phoenix also carries First Aid supplies, traffic equipment, PPE (hard hats, glasses, gloves, high-vis apparel), and gas detection equipment.

Welcome to our newest club member! VE7CFY

Welcome to the Kamloops Amateur Radio Club!

Ron Stolp, VE7CFY, is our newest member having joined the club in December.  Ron recently wrote his exam with Mark, VE7ARN, and passed with flying colours!  He received his Basic with Honours qualification and chose the callsign VE7CFY.

Ron tells us that many years ago in high school he was studying for his license, but back then it required morse code as well as a lot of electronic circuits, and although a few of his friends stuck with it and still have their licence, Ron wasn't so fortunate.

Currently he is very involved with horses in various disciplines, and he likes to travel to Arizona with the horses in winter (with the exception of the last few years). Ron thought that having an extra form of communication would be a good idea because cell phones don't always work where they ride so ham radio was a good choice.

Ron isn't on the air yet (he is waiting delivery on a couple of Baofeng portable radios that are stuck in Richmond) and hopes to be making his first QSO with one of us soon.

Here are a couple photos of Ron on his horses (I suspect you can tell which photo was taken in Arizona -Ed.), including his newest horse which is in Mission where the two of them are taking more training.

Welcome to the KARC, Ron, and thank you for becoming a member!

North American QSO Party 2022

The North American QSO Parties are favorites of beginners and seasoned operators alike. The NAQPs are low-power only (no amplifiers allowed) which makes for a lot more breathing room on the bands. Small stations can generate very effective “runs” in the NAQP  contests. Multipliers count once per-band, which makes for an exciting format, as multipliers can be “moved” from band to band.

The NAQPs allow stations from all parts of North America to be in the running for the top spots. The 12 hour format allows participants to do some great contesting, yet still have time for other activities during the weekend. Participants can enter in the single op or multi-op categories and also have the opportunity to combine up to five separate single op scores into a team score.

North American QSO Party, CW    1800Z, Jan 15 to 0559Z, Jan 16

North American QSO Party, SSB    1800Z, Jan 22 to 0559Z, Jan 23

North American QSO Party, RTTY    1800Z, Feb 26 to 0559Z, Feb 27

KARC Repeater Update: Rainbow Country Net now daily on VE7RLO



If you were listening to VE7RLO this morning you may have noticed that the Rainbow Country Net (hosted on the VE7RPT repeater in the lower mainland) was active on our VHF and UHF repeaters.

VE7RLO will now automatically connect every day to the Rainbow Country Net, which starts at 09:00 AM PST (with early check-ins at 8:45 AM).  This is one of the most popular nets in BC with hundreds of people checking in.   VE7RLO will automatically disconnect from the net at 10:30AM, so hopefully you can check in by that time!  If not, we can tweak the script timing.

If you need to use the repeater during the net to call someone, or if there is an emergency, etc you can disconnect the VE7RPT Allstar Node by sending DTMF code *1435450 (which will disconnect VE7RPT), or *10 (code to disconnect the last active node, which should be RPT).

Don't worry about reconnecting to the net, it will start up automatically the next morning.

If you find this annoying and driving you crazy, please let me know.  This is a bit of an experiment to see if it might be enjoyable for club members.  If it is not working for people, it is easy to scrub the script and go back to how things were.

73 de Myles, VE7FSR
