Ham Radio 360: Workbench- 27 Field Day After Action Report

This week, George and Jeremy take a look back at Field Day 2017 and the things that we made to make it a great one. We also spend some time with Jason K6DGN to talk about his USB HT Battery Charger and some of his other interests.

  1. Thoughts about KX3 mounting. I need access to repatch the mic and speaker to convert to using a sound adapter for digital modes. I’ve recently used the Sound Blaster Play3 and it’s really nice (96K samples in a small USB package for about $30). I think the jack is “Normaled” so you can’t patch in an extender unless you always use an external speaker. But that external speaker is essential since the built in one would be very muffled in a tightly packed go kit. I also got the Heil adapter for my ProSet headset so I can use the foot switch, mic and headphones. Another reason to have access to the side of the KX3 for patching.

    I’m looking to use Macro1 for SSB settings and Macro2 for Digital. So far I’ve found I need to change PTT=OFF, Mic Bias=OFF and Mic Gain=03 when setting up for digital via a sound adapter.

    I’ve added the bigger heatsink to the KX3 so airflow over that is useful. I made 3 PSK31 contacts on 10M during Field Day and even one on 6M.

    Since the KPA100 is so well integrated, is it really required to have it facing to the front? I think it can fit it behind the PX3-KX3 combo on the front of one rack shelf and keep the portable case to 3RU tall. Again, I would include a fan to cool the amp.

    We built and added tuned stubs to help with station isolation. Band pass filters were also in use on some stations.

    The current draw on my IC-7100 is 0.7A when on and listening.

    I keep wondering if I can simply connect a laptop to my 12v distribution. Probably it might overheat the input traces if they run a higher current with the lower than 18V they want. I’m concerned about these 12V to 5V devices making RF noise to charge the latest netbooks with USB.
