I'm trying to get all my podcast feeds in my regular #rss reader, so they're not just stuck in Apple or Castro siloes.
This site has been a big help. Type the podcast name in the search. If you don't see a clear result, restrict the search to "The Podcast Index" on the results page. Scroll down. You'll see a ton of icons, but plain-old-rss-feed is the last one. https://podnews.net/
