Upgrading the IC-3SAT, Part 2

Today, I was trying to figure out why the internal battery didn’t work on this IC-3SAT.

I swapped it into the other IC-3SAT and it worked fine! It seems that the switch selecting internal or external battery is faulty on one of the units. So I swapped over the PL tone board and internal battery to the other HT and it works great.

The completed and fully-working IC-3SAT.

Yay for spare parts!
