Great Breakfast Meeting

If you missed it, we had a great time. Good Coffee, good food and good friends. Look for plans coming up on the September meeting. Perhaps it will be cool enough to go to the park after the meeting? If anyone has ideas for a presentation, topic or special guests please send them our way!

The next meeting will be taken up by the Joplin ARC HamFest!! But we still have our weekly coffee at Spellbound on Wednesdays at 9am!

SEKARC SLOW SPEED CW NET

The purpose of the net is practice for CW operators and to make us proficient if we ever have to use net controlled traffic. It is a SLOW SPEED net and is designed for the new CW operator and those of us who need the practice or are just learning.

Please try and keep your speed below 8 wpm.  Our operating frequency will be between 7.057 and 7.058 MHz .  I will try to use 7.057.5 but if it is busy QSY up or down between the above.  Let's have a good time and use the equipment that works for you.

Field Day Balloon Antenna

Be sure to watch the video below.....

Balloon Antenna Success
by Tyler Costantini KBØPQP

The balloon antenna worked very good what was surprising was the broad tuning range. The antenna was a 1/4 wave at 160m but we never measured the length we just used the antenna analyzer. It was first fed with a random wire tuner at the base that didn't provide a very good match. Next we just used a BNC to banana adaptor and put the wire right in the end of the 50ohm coax which lead to my MFJ 989c tuner that setup worked great. We could tune 160-20 no problem any part of the band and it seemed to radiate well. We put a 2mH choke between the radial and ground to act as a DC ground to remove static. I couldn't notice any change in the behavior of the antenna with the choke in place so I guess my math worked. It's 50+ turns in a FT-240 type 43 toroid.
