The performance of my satellite downlink station is nowhere near as good as I would like. I been doing some various troubleshooting measures to try and figure out what is going on. In my previous post, you can see some of my explorations about antenna tuning. In this post I took my first pass atContinue reading “TDR with the NanoVNA”
For my satellite ground station I built an antenna from the plans by WA5VJB http://www.wa5vjb.com/references/Cheap%20Antennas-LEOs.pdf I originally built a 7 element 70cm antenna. But then added on a two element 2m one. While I had tuned the 70cm antenna, it was tuned a little too low after the second cut to shorten the driven element.Continue reading “I cut it twice and it’s still too short!”
I’ve been slowly working towards building a satellite uplink and downlink station for years. I have finally reached a point where I finished building the station and have Receive some signals. The performance is rather abysmal, I still have a fair amount of work to do.
