hi Ken
after replacing every board in my old FT-817 by brand new ft-818 boards (see in this group)
I could set current to the FINAL UNIT as mentioned.
BUT no power out at all. Carrier is ok... Receiving is ok on front / rear socket...
Should use the scope to see whats going on. Frustrating....
cheers - Ray, DL1EGR
