[amsat-bb] Handheld for LEO satellites?

I ended up getting two Baofeng UV82R HTs. They work fine, but they have the
same problem of the UHF radio desensing when I transmit with the VHF. So,
not full duplex.
I did just buy the Arrow Duplexer to go with my Arrow Antenna. My plan is to
still use two radios and just use the duplexer on the VHF uplink side to see
if it kills the third harmonic enough to prevent desensing of the UHF radio.
I can give a report after I try it.
If anyone sees a problem in my plan, please speak up soon before I fry
