[amsat-bb] FT847 satellite power output problem

Hello all; our F6KBR radio-club is almost ready to be active very soon via satellites with Yaesu FT847 rig but we have a big problem: no power output on SAT position. Everything else is OK, any mode... We tried full Reset (menu #39) but still same problem.

Thanks for any help. 73 de Michel F6HTJ
