Off the grid<\/figcaption><\/figure>\n\n\n\n

I ran a solar powered off-grid portable op today.<\/p>\n\n\n\n

Equipment:
Yaesu FT-818ND
USB SignaLink
FTDI CT-62 CAT cable from Valley Enterprises
2014 Dell Laptop
Duracell 9ah AGM battery
Hardened Power BattBac
Harbor Freight 100watt solar power kit
N9TAX roll-up 2M\/70CM Slim Jim antenna<\/p>\n\n\n\n

Operated 2M voice into WF4X (147.285) repeater in Defuniak Springs. QSOs with K4NDJ and KK4WDR.
Operated JS8 at 5 and 1 watt. QSO with KK4WDR at fast mode, we tried turbo but I had some bad decodes. Distance was about 35 miles and we had good decodes with signals at -12 SNR. Grid square I activated was EM60vs.<\/p>\n\n\n\n

Things learned today:<\/p>\n\n\n\n

The bad<\/p>\n\n\n\n

  1. Bring stuff to get HF wire antennas in the air, not all campsites have trees. I planned to get on JS8 and Winlink on 40m.<\/li>
  2. Just because your computer worked on JS8 3 months ago doesn\u2019t mean it\u2019s gonna work as soon as you wire everything up. CAT control wouldn\u2019t come up and took some tweaking. A notebook with settings recorded in it would help with the trial and error.<\/li><\/ol>\n\n\n\n

    The good:<\/p>\n\n\n\n

    1. 100 watt solar into a 9ah battery runs everything but won\u2019t sustain operations overnight. It\u2019ll run everything about 2 hours on battery.<\/li>
    2. 12v Laptop power supply works well on this setup but the laptop consumes a lot of power.<\/li><\/ol>\n\n\n\n

      Next operation will be using a raspberry pi as the computer and an iPad as the display connected via VNC.<\/p>\n\n\n\n
