I got my first DX satellite with the 1.8 meter dish in the form of Simón Bolívar at 78W. I was making notes where the satellites are in relation to the actuator numbers and ran into the 78W satellite by accident. Several transponders were scanned on this satellite, and i actually watched TVO for a few minutes. This satellite has no signal this afternoon, but I expect it to be back when conditions are at the best such as early in the AM. Below is a screenshot that I took of some scanned transponders when I first found 78W.
I was able to get 78W with a reduced signal on the 1.2 meter dish but I also got several transponders from 77W when I did a blindscan. This did not happen on the 1.8 meter dish which is to be expected because the signal beam narrows as the dish increases in size. A narrow beam usually means a stronger signal, but it also means the dish has to be aimed more precisely.
