I bought an arrow antenna at the Raleigh Hamfest this past weekend. It has been about 15 years since my last satellite QSO. This evening I walked out in my backyard and with the TH-D72 I had contact with a couple of hams. on SO-50. I apologize that I could not remember the calls as I heard them. I am 78 now and the brain is not as acute as it used to be. I had no way to write them down. Holding the antenna and the handheld and trying to shift downlink frequency and uplink back and forth is a challenge. I guess I will need to try a voice  recorder..
