Hi Sean. In my (quite limited) experience I have typically used 144 MHz SSB
to coordinate contacts on 1296 MHz. During my last attempt at long haul 1296
contacts I found a 50 watt 144 MHz radio and a 4 element beam was more than
adequate for coordinating a contact at 1296 with 10 watt radios and 55 element
antennas at each end.
I worked a number of stations on the 144 MHz liaison frequency that I wasn't
able work on 1296.
Your mileage may vary (:
