The old Icom 703 is good.  Used it during Uri Ice Storm.  Could get into DFW on 
7290.  Easy on battery.  And has ant. impedence tuner.  Size of the 706 series. 
 But I think it is more sturdy platform than the 705.

If I need more power, can use an Italian amp and LDG tuner.  If I can make 
contact on QRP, I can.  If not, I can add power.

The disadvantage is having the amp and extra tuner and 2 short coax cables.  
Plus 703 is out of production.

Advantages ate being modular, and the 703 sips power not transmitting

KJ,

How many amperes do you need from the battery?

I want to put a battery (see other thread) and a solar panel together to be able to run my radio POTA/ARES, but while I can math my way into what I think I need, I’d like to hear from folks doing it, empirically, to get feedback on what’s actually worked/didn’t in the field. My math says a 55AH deep cycle with a 220W solar kit should do really well during the day, but I’ll still need to curb power at night, assuming a 25% duty cycle.  If I want a 50% duty cycle for FT-8, the numbers (read: costs) aren’t fun to think about….

Who’s doing this, and what can you teach me?
