We had a GREAT antenna building class after the Feb 4th meeting.  Dewayne KB9TQJ provided materials (and (Knowledge!) to build a 2 meter yagi(s)which was tuned to the repeater freq. with a SWR of 1.2 to 1.7 average.  It was a great way to spend time with some GREAT people and friends.   Now we need to put together a FOX hunt, Now that we have some directional yagi(s).  It was a really great time and good club comradery.  Thanks again to Dewayne for making this possible.                                                   

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.

With 35 in attendance, SPARK held its monthly meeting at EMA Headquarters this morning. After the standing committee reports we discussed several things. Paul *KD0ETL) gave a final report on Winter Field Day. We had many members who participated this year and a great time was had by all. Bret (W0VK) reminded members about the upcoming storm spotter training to be held on March 2nd. The Sedalia-Pettis EMA has invited members of SPARK to attend this training. This training is closed to the public but since SPARK is a vital asset of EMA we encourage are members to attend. The location of SPARKFEST 2023 was secured and will be held on Saturday October 14th at Our Savior Lutheran Church again this year. After the meeting Dwayne (KB9TQJ) conducted a Antenna Building Class that was well attended. Our next scheduled meeting will be held on Saturday March 4th beginning at 8:30am held at EMA HEADQUARTERS located at 1511 N. Ohio in Sedalia.
