The setup is currently into a dummy load and is powered from my bench power supply for the radio and the Pi is running off my phone charger.
The next jobs to do for this is to get the shelves in the shed and to get the antenna built (which I plan to make resonant on 144.800), then of course batteries and solar panels to get power to the shed.
So far the tests show promise, the transmissions are received by my Yaesu FT2D and it is used to test receive on the igate which seems fine.
I have two You Tube videos on the subject and they are attached below.
