RE: Handheld for Echo and FM Sats?

Yes, the FT-51R is full duplex.  Have you been opening the squelch
all the way to hear the bird?  Try this, open the squelch all the
way.  Put the satellite downlink in the sub band.  Adjust the audio
so you only hear the sub band.  Then transmit on the main band.  It
should work full duplex just fine.

You can test it this way if there are active repeaters in your area. 
Put an active 70cm repeater in the sub band.  No need to open squelch
and leave audio balanced.  When the repeater comes on transmit into a
local 2 meter repeater.  You should be able to still hear the 70cm
repeater while transmitting on 2 meters.  It is possible there is a
menu function that has been activated on your radio that mutes the
sub band while transmitting, but I have not seen it before.

73 and Good Luck,
