While playing with the L/U mode I've had some limited success. I believe KO4MA & VE3NPC have barely heard me on the up link during the last 2 nights. Not sure what my issue is but my setup is IC910, L-band module, 20 amp brick, 80 ft hardline to tower, 1 vert stacked pair M2 35EZ antennas. Downlink works well as I can copy all. I've made various U/L freq adjustments from 1268.699 to 1268.705 with some QSO success. Would appreciate any input so I can QSO with all.

Bruce,
I was on last night, and heard you a couple of times with a very strong signal. Other times fairly weakly. One thing to check would be your antenna directions. You will have a fairly narrow beam width, especially vertically, with those antennas. I recalibrate my array at least twice a year, summer and winter. I especially notice the difference when the mode S downlink is active, as my dish is the tightest of my antennas.
