The problem with almost all ham shows/podcasts is in producing good content. You either have to be very niche or produce very high quality content on a regular basis, which is hard as everyone of these shows/podcasts I've ever seen is done by very few people, most of these are produced by one or two hams at most.
I want to try to stay away from naming/shaming individual shows, but there are a few that do it very good, and some that do it very bad. Linux in the Ham Shack is a audio podcast I've found to almost always be very informative and well produced, but it's a pretty niche area (lhspodcast.info). TX Factor (
TX Factor) is about the best produced video podcast on amateur radio, but their releases have at times been sporatic, I'm sure from the difficulty in producing professional and well informed content as a side gig.
One that I recently tried again and was still somewhat dissapointed in is Ham Nation, a show produced by a big podcasting network, twit.tv. I found the early episodes to be well produced, and they always had a variety of topics. As much of the content is produced independently by various hams involved with the show (George from Amateurlogic is a regular contributer to Ham Nation as well), it varies from excellent (some of Bob Heil's older segments, Julian, N3JF). It also is let down by some poor content as well(Bob seems to be not quite a sharp mentally in the few recent episodes I've watched, Gordon West has always been unwatchable). This is what happens when you try to release a show weekly and need to fill content. I've also never been too happy with Icom's deep financial and content involvement with the show. You can see this in the overabundance of Icom related content and at times a reluctance to talk about products that may compete with Icom, such as DMR.
