I like both modes of operation. Although, for the short time scale of an ISS pass, I would favour packet more. This been for the more efficient side of packet with more operators able to make a contact. On repeater mode, a small amount of operators appear to be running high power; and love the sound of their own voice. Thus not letting another operator have a chance to make a QSO.

I have to go with Packet just a little bit more that the Repeater. It is great talking to folks and it is likely that more people could do repeater with so many dual band radios but I can make more contacts during a single pass on packet without anyone complaining about hogging the radio.

I like the repeater more.
If ISS was using a FTL0 9600 bps system (like AO-51, GO-32 or UO-22) I would have gone for the packet radio.

I agree with the previous comment about liking packet better.
For one thing, you only need a single band radio and antenna for packet and old style ISS voice contacts. Now you need BOTH 2m and 440 AND be concerned with doppler shift on the 440 side.
The cross band repeater is neat, but WHY?

I am also voting for the packet as you can not send emails via the cross band repeater. Both should be operational on different frequencies and no-one would winge about anything. Kevin VK3UKF

I like them both, why can't both be utilized in an alternating fasion.
