I want to switch al my antennas fom my shack. Several designs where found on the internet, but not good enough for me.
I start with some experiments with the Arduino controller board, so i thought it must be a switch controlled by Arduino, easy for use, and easy to change antenne names. The switch PCB was ordered from Mikael SM3WMV And i ordered all the components by Farnell.
The basic program was written by Johan, PE1RWL and it is available with the schematics by sending my an email.
To travel with your equipment it is important to protect this. The Lafayette Survivalbox meets all the requirements, waterproof, shockproof. I bought 2 from this boxes by Portofoonweb.
Building Elecraft stuff is fun! Also this P3 kit, a real addition for the contester. Here a video from some CW sgnals
New bandpass filters for our contest station PI4M. Based on the famous W3NQN design, delivered in a kit by 5B4AGN. I’d like to the to do the solderwork, espacially SMD. Winding the coils is not by cup of tea, so this credits goes to PI4M member Kor, PA0KDV. 3kits available now, maybe more in the future…
For the big contests the crew of PI4M are always busy to improve their antennas. For the upcoming CQWW SSB contest, we need a better antenna for 160m.
We have chosen for an inverted L. More pictures and info available after CQWW SSB 2014
-Vacuum capacitor 1000pF
-18m Spiderbeam pole
-12.5m Spiderbeam pole
-18 radials 20m each
Every year in February the PE3V crew come together to participate the Dutch PACC contest. The last year result was a 3rd place in the M/M section. Can we improve our record this year? The claimed scores have been announced:
PE3V 1.378.564 (YES!)
We have to wait for the final score, we can only show you the pictures of our wonderful weekend …

Sometimes it will happen your AA200 analyzer will be defective by getting to big signals on the input. By measuring large 160m verticals, when measuring while a near station is going TX with QRO etc… The input FET SGA6589Z can’t handle such signals and will break..
It is easy to replace this FET when you have some experience with soldering SMD components. Only work with ESD safe tools!!
It was not the first time for me to replace this FET. Few years ago my AA200 was also getting big signals from our 1/4wave vertical for 160m. Big AM broadcast radiostations near our frequency was the reason…
Rigexpert was kind enough to send me some new FET’s, so i can forward for a couple of years 🙂
One of the biggest contest of the year is the CQWW contest. In 2012 we participate for the first time, so our goal for this year was exceed our score. We build some new antennas and invest in our equipment. Unfortunately we have to pull down the 3 antenna towers sunday afternoon because a predicted heavy storm. After this we set up some verticals so we could be active unitil the end of the contest. Here PD9X in action.
