Working the SO 50 Satellite Portable from EM70 Lynn Haven, Florida

About 7 AM today, Bob KK4DIV and I worked a SO-50 satellite pass..We both got a couple of contacts. I admit to being a neophyte at this. is a great reference. I have a few confirmed contacts at this point. You can get the job done in many ways. The Saudi Oscar 50 bird requires a VHF uplink and a UHF downlink. The downlink receiver needs to change frequency during the pass to adjust for the doppler effect .I have a Yaesu FT-60 HT which allows memories to have VHF/UHF pair. That is convenient but not mandatory. Bob KK4DIV used a FT-8800 mobile rig successfully today. He took advantage of the dual watch feature. I purchased an Elk antenna but Bob used a tape measure yagi he made for fox hunts. So you may already have something usable. I found out today why they recommend duplex. Duplex allows you to hear your own signal returned on the downlink. I forgot to change the channels for the doppler. So when I threw my callsign out they heard me but I did not hear them, That was bad form on my part. I have a duplexer on order. That way I can hook two HTs to the same antenna for duplex. Bob got away without a duplexer with the FT-8800.

Working satellites outdoors portable fits in the style of operating I like. In fact, Eddie ZS6BNE enjoys operating Sats and he put in a Sat bonus for the RaDAR Challenge. Field Day has a Sat Bonus as well. I am going to take credit for my Sat contact at Gulf Islands National Seashore for the Five Star Activator NPOTA bonus. The AMSAT-NA awards are based on working four digit grid squares. I see that moving among the grid squares can be lots of fun and helpful to the other ops. I am using LOTW to log and confirm contacts. I got started with LOTW doing NPOTA. I look forward to learning more about Sat ops and experimenting with equipment. I had a good time operating with Bob today. It was worth getting up early. Enjoy the videos.
