Winter Field Day’s Core Principles:

Natural disasters are unpredictable and can strike when you least expect them.
Your training and operating skills should not be limited to fair-weather scenarios.
Preparedness is the key to a professional and timely response during any event.

WFD is an opportunity for ham radio operators to practice portable emergency communications in winter environments as the potential for freezing temperatures, snow, ice, and other hazards present unique operational concerns. WFD is formatted to help increase your level of preparedness for disasters and improve your operational skills in subpar conditions.

Open to all club members and we hope you can make it!

For those that couldn’t stay for the antenna build here is a repost of an antenna project similar to our antenna build today after the club meeting.   Daren – KDØOPS

Fellow Ham’s!

While we are all exercising our Social Distancing these days, I thought this would be a great time to share what I have been doing.  After researching a bit, I found many diagrams for a great Yagi Fox Hunt Antennas.  These diagrams were all very similar so I decided to just pick one and go with it.  I found through the process it was fun and really not too hard to make, I did substitute a couple things because honestly I just used what I had on hand, that is the fun thing about this project!
So, I have it completed and plan on using it to check in to our net tonight just for fun and to show everyone how it works.  I have added some pictures so you can see the finished project and how basic it really is.  Here is the link for the instructions I used, just for your reference if you want to make the same one I did.
I hope many of you that don’t already have one of these fun little Yagis decide to make one just to have on hand so when we do get the opportunity to have a Fox Hunt you will be ready!!


I hope you all enjoy this as much as have.

Bret Thanks for the Ideas.  Here is my build:




Some things that I researched and did a little differently were, I used 3/4″ PVC (Already had it on hand), Used some velcro to wrap ends of sharp tape measure ends and also serves to hold elements in the collapsed position,  added choke (RF cable around PVC (6x’s),  Also used those tiny hose clamps that I never find a use for anywhere else (I just put to together!).  Put BNC connector on end.  Took my antenna analyzer to this and it’s about 1.5:1  @ 144.5 , 1.1:1 @147.00 and 1.5:1 @ 149.0.   Also, have enough left out of the 25ft tape to make another one.  IF anyone needs some tape measure elements just ask first come first serve.

– Thanks and 73’s, Daren – KDØOPS

Bothwell Auxiliary January 2022 Volunteer of the Month

Every month, the BRHC Hospital Auxiliary selects one of their volunteers to be recognized as a volunteer of the month.  January 2022 saw SPARK member Harry Burford, KØTV in the spotlight.  Harry has been working with the Amateur Radio station installed at the hospital for over 12 years.  He started as a Red Cross volunteer, but those volunteers were recently absorbed into the Auxiliary organization after the Red Cross closed offices in Missouri.   Here is a copy of the article from the Auxiliary newsletter. .
