Hi everyone.?
Many of you know I operate remotely. I’m currently building a remote sat station that needs 2m and 70cm. I am using an SDR play for receive, streamed over a raspberry pi server. Some sats are 2m up and 70cm down and others are vice versa. This means I need to remotely swap over the antennas between tx and rx.?
This is where the Clifton connection comes in. G0DCG gave me his venerable 2m valve amp with a 4CX150 many years ago. I never got it going, but the coaxial transfer relay ended up in my box of useful bits. It’s now been pressed into service in this project. Thanks Martin!?
The attached photo shows the SDR rx, relay, 28V relay driver board and a preamp bias T all in one badly built box. Last place in the Clifton club construction contest this year.?
cheers
