Yeah so one thing to watch our for is a lot of the data over audio stuff that works over RF, may struggle over cassette because of the wow and flutter. It will generally work on the same deck you record as you playback, but problems arise when you give to friends.
I discuss this a bit more in the first episode.
But yeah! Let's keep experimenting. What's nice about ham modes over cassette vs RF is you can encrypt 😉
So I'm noodling some projects there.
