Announcing the July 2017 SPARC Mobile Installation Contest

Are you proud of your mobile installation? Why not enter it in the first annual SPARC mobile installation contest? At the regular July SPARC meeting on July 7th, members are welcome to enter their car in the contest for a chance to win a nice prize in either the HF category or VHF/UHF category (or both). The judging criteria are summarized below. Click here for more detailed judging criteria. It is not about the cost of your equipment, but how finished and polished the installation is. The more your installation looks like it came that way from the factory, the better.

HF and VHF/UHF entrants judged on:

Power Connections         Antenna Mounting

Grounding                         Cable Routing

Radio Installation              Operational Safety Concerns



All cars entering contest should park in front of DMI building (car show style) by 7:00 PM.  Judging will start at 7:15 PM. To take advantage of the light, we will have time for people to look at the cars until it starts getting too dark. Then we will go inside for the regular meeting and then the judges will highlight what they saw in the contest and announce the winners. Think of it as a meeting in reverse.

So tie off those cables, neaten that rat’s nest under your dash or under your hood and come out and enter your car–or just get ideas to improve your own installation.

Please contact Tom Schaefer, NY4I at or 727-437-2771 to register for the contest or with any questions.

Automatic Antenna Switch Decoder added to W4GAC Station

Ron KP2N and Tom NY4I added a Top Ten Devices Band Decoder to the W4GAC station. This switch ties into the existing Six Pack antenna switch. The idea is that rather than the operator having to select the right antenna, the Band Decoder follows a signal sent from the radio that tells the decoder what band the radio is on at the time. The corresponding position is then switched on the antenna switch. So when the radio is on bands 10m – 20m, the Log Periodic is selected. When it is on 80 or 40m, the dipole is selected. It is also possible to use alternate antennas (in case we want to have a 40m vertical as well).

This addition is also needed for the remote station as the manual selection switch would not work with a remote station to change antennas. Below are a couple of pictures of the project. One is the band decoder and another is a handy little DB-25 breakout Ron used to get the pin outs correct before he soldered up the DB25.
