[amsat-bb] Linear sat half-duplex operating tips?

I have been operating the linear sats over the past week on half-duplex, using a single IC-7000 controlled by SatPC32.  I've made several contacts, but it has been quite difficult.  Obviously the best remedy is to get a second rig and run full duplex, but in the meantime, does anyone have any tips for successful half-duplex operation?

One tip I received from NJ1H is to announce at the start that I am running half duplex, since most stations manually adjust the uplink so that the
downlink stays constant. If the other station knows I am running half-duplex, he should adjust the downlink instead of the uplink.

Any other suggestions?
