Hi Paul,

WB8RJY, VE4AMU and I noticed a weak signal on that pass - just in the 
noise. Was that you?

Good to know you are seeing the nominal frequency being a bit high as 
well. More testing is needed. Both of my passes were 5-6 degrees at 
best. I'd like a good 30 degree pass to check tuning and ERP for best 
quieting on the uplink.
