Hi all,

I made two videos that might be helpful to some members here.

The first shows how I operate my 2.4 m dish hydrogen line telescope fully remotely. The dish is at a low RFI remote site 1000+ km from where I am, running over the internet on a Raspberry Pi 500.

The second covers the Wow! signal and my attempt at an amateur SETI pipeline in Python based on turboSETI's de-Doppler method, reimplemented in NumPy so it runs on a Pi with no GPU. So far I have only detected RFI, but ruling signals out has been a good learning exercise. I have tested it on two small home setups so far, a WiFi grid dish with a DD H1 feed and a small TV dish with a Ku PLL LNB.

The Ku band had far fewer RFI issues than 1420 MHz. The next step I'm working on is running it on the 2.4 m dish. (Dashboard screenshot attached, it still has a lot of bugs as I'm trying to improve it.)

Quick note: I used an AI voiceover as I was short on time, so apologies if it sounds a bit robotic.

Questions and feedback welcome.

Thanks.
