               2018Stuart Hamfest

    The 2018 edition of the Stuart Hamfest was held on Saturday, March 17th at the Martin County Fairgrounds.  We had an absolutely perfect Florida winter day, filled with good food and many Ham Radio friends.  Our very special guest this year, Bob Allison WB1GCM, from the ARRL Lab, led a forum on Software Defined Radios (SDR).

    An Icom IC-7300, and many other prizes were given away at the event.  Visit to see if you are a prize winner.  If you missed the hamfest this year, next year's Stuart Hamfest is just around the corner!

    2017 Stuart Air Show

    The 2017 Stuart Air Show went into the history books as a remarkable event for many reasons!

    First, an antenna tower that relocated itself overnight, and then later refused to go up and ate a bunch of coax and rotor cable for breakfast.  Once repaired, however, the pileups on 20 meters just wouldn't quit!

    If you have never watched an aviation fuel tanker being pulled out of the mud by a tank, complete with a wary and watchful 50-cal turret gunner, you have missed something!

    On Sunday, a typical Florida afternoon thunderstorm transformed our small tent into a refuge for a half a dozen unexpected guests, which were forced to learn Morse code, or be evicted!

    None of it would have have happened without your help!  Well done, to all those who participated!

    The JOTA is not a contest. The idea is not to contact as many stations as possible during the weekend. It is about Scout to Scout conversations to learn about one another and the country where they reside.

    All participating groups are asked to send a report of their activities to their National JOTA-JOTI Coordinator (NJC) after the event.

    For those of you using Echolink, there are now two conference nodes designated for Scout contacts. You're familiar with *JOTA-365* (node 480809). We also have *JAMBO* (node 832996). For further Scout frequency information including D-STAR, DMR, and IRLP, go to

        Field Day 2017

    MCARA/MCARES members began Field Day preparations on Friday by erecting 8 antennas and two towers, and setting up four radio stations.  Then, on Saturday morning, Tom K4TMA fired up the BBQ!  And the weekend just kept getting better from there!

    The weather was perfect, the radios worked flawlessly, the food was fantastic, and we even made some new friends!  We really didn't want to break it all down on Sunday!

    The second annual Maker's Faire was held on Tuesday afternoon, May 2nd, in the gymnasium at the Pinewood Elementary School in Stuart.  MCARA and MCARES members presented several educational activities in an effort to ignite the fires of creativity in those attending, both young and old.  Conductive dough was used to teach basic electrical principles, and, when connected to a RaspberryPi-based 12-channel capacitive touch-driven sound synthesizer, to entertain.  In addition, a GOTA station served to segue to our favorite hobby, Amateur Radio!
