Greetings friends, I am aiming to make a solar powered briefcase for my Yaesu FT-857D. I was hoping some one more experienced then me with solar and radios can let me know if this is going to work. I can only seem to find videos for like ammo can solar systems. Solar Panel for System. https://www.amazon.com/gp/product/B00W813E4I/ref=ox_sc_act_title_1?smid=AV16HZDTPF1LD&psc=1 This is a 12v 20W solar panel. My fear with this panel is that it wont recharge the Deep cycle batteries fast enough for continues HF listening (and a bit of talking). What I like about this panel is it will fit on the outside of the Brief case keeping it very portable. Batteries for System https://www.amazon.com/gp/product/B00KAKPGNQ/ref=ox_sc_act_title_6?smid=A33N703ELCFX8U&psc=1 I was going to daisy chain these batteries together. I do hope they will work just fine with my Yaesu FT-857D and my selected solar panel. Charge controller. https://www.amazon.com/gp/product/B06XMY68L6/ref=ox_sc_act_title_2?smid=A2WI2LFG1JAJEM&psc=1 My concern with the charge controller is it is large. But I like the display for batteries and voltage and if I wanted to add solar panels later I can. Can any one think of any other issues this could have? Safety Kill Switches https://www.amazon.com/gp/product/B005R5Z7OC/ref=ox_sc_act_title_4?smid=ATVPDKIKX0DER&psc=1 This is what I was going to use as a kill switch from the batteries and the Solar panel and use the last switch for DC lighting later. Then naturally my grounding Plate https://www.amazon.com/gp/product/B003175XJW/ref=ox_sc_act_title_5?smid=ATVPDKIKX0DER&psc=1 Might be a bit large for what I am doing but that's ok. Please let me know if you find anything that wont work together? I shared my concerns with each piece. I also would like to know what wire gauge I should probably use for this thing I have some 12gauge copper wire? Additionally I am open to suggestions on HF antennas, if no suggestions then I have to wait until I can make or buy a magnetic loop antenna.
