I do know there are at least two other podcasts out there, both of which are part of bigger generalized podcasts that cover a broader range of media, but I don’t know if any of the hosts are active on the forums:
The Waiting Room: A Quantum Leap Podcast is a sub-podcast within Radio Tekkers. The hosts are BenNny and Si, and they started covering the original series in 2022. They’re currently on Season 3.
The Rewatch Podcast covers a number of different shows and movies. They started with Sliders many years ago (they might have actually been the very first Sliders podcast), and they moved on to a number of different shows like Lois & Clark, Heroes and the original QL. They also cover the revival series as it airs, but it’s all part of one huge podcast. So, for example, “Nomads” was the 578th podcast episode. Cory and Tom are the co-hosts for the QL episodes.
