A couple of months ago I volunteered to provide a narrowband transponder demo station for use at the AMSAT-UK colloquium in October. Now I have to convert this collection of parts into something suitable.
I have chosen to use a single 0.8m dish with POTY dual band feed for the antenna. I had previously purchased a 20 / 25 Watt Spectrian amplifier from 'Pyro Joe' via e-bay. The final major component is an upconverting mixer to take 432MHz in from an IC9700 and to output a signal on S Band. This will be designed around some available parts and built on a PCB to be ordered from China. - What can go wrong !!
Hopefully this short series of posts may help people trying to assemble a station of their own.
