Pre-St. Kitts equipment check
Just before the Montserrat trip I also did this exercise. I set up a station with only those thing found in the Pelican case. I participated in the North American QSO Party just long enough to be sure thing were working. After putting 50 QSOs in the log I packed everything back up and began checking antenna stuff, coax, tools, and so on.
As fellow blogger David (K2DBK) says, "Turn in your log!" I did even for this very light effort and actually beat a few other fellows here in MA. Go figure!
I have had several inquiries about the use of the mixer and the capture of audio. The system is quite simple. The Behringer UB502 Eurorack mixer takes audio from several sources and combines them into a single audio feed. The connections are as follows:
- Icom IC-7000 external speaker to mixer input 2/3
- Yaesu FT-817 headphone jack to mixer input 4/5
- Heil headphones to the mixer headphone jack
- iPod headphone jack is connected to mixer tape in
- Mixer tape out is connected to the Belkin TuneTalk iPod recording device
There is a button on the mixer called Tape to Mix which allows you to play back the iPod audio through the headphones without changing any wiring.
The mixer weighs very little but the brick on a leash power supply is hefty. Also, in order to keep the audio clean, I need to snap on a bunch of ferrite (which also eats into my weight budget). This is a tradeoff I'm willing to make, though, so I can meet one of the DXpedition goals: capture audio and video from the adventure so I can show people how much fun I had later!
