Well, most of the other programs that were on WBCQ and WRMI are still on. WRMI has reshuffled their schedule and recently QSY'd their entire 11580 broadcast schedule to 7780, but WBCQ is WBCQ. I had a really solid copy of Marion's Attic and Uncle Bill's Melting Pot yesterday out here in the west. Fred Flintstone's Music Show (Saturdays at 0000 UTC, or Friday evening for most of us, on WBCQ) is sadly no more, though, but I don't think that has much to do with Stair being almost totally gone from HF.
If the airwaves do seem emptier, it's no illusion. I remember about a year ago, Stair was the topic here (maybe in the Ryver chat), and I went out to short-wave.info to do a quick estimation of how much he was on the air. (This was prior to his drastic cutback in hours that happened around March.) It looked to me as if he had something like 275 air hours every single day on average, and could be on as many as 15 different frequencies at certain times of the day. If you looked at WRMI's programming schedule spreadsheet at the time, it was all full and at least 75% of it was Stair (excluding 9955, which has a ton of different shows and requires them to keep a separate schedule). Take that away, and everyone will notice the difference.
I hope WRMI at least finds new customers. If I were them, I'd contact every national radio service with English, Spanish, and French broadcasts and offer to relay in North America. I'd try to lure them away from WHRI (who has Voice of Vietnam in EE and SS, and KBS World in SS) and even Cuba (their CRI relay is a joke anyway). It was cool that the added RAE and Radio Tirana last summer, and the fact that Radio Prague does it this way, which I think is their only SW broadcast, shows that other countries that don't transmit on their own aren't necessarily opposed to relays. Of course, I'm assuming that they want this. I've heard that they have a large cattle ranch that helps fund the cost of operating it, and I wouldn't be surprised if operating the station at a loss helps at tax time. BUT... that's just a rumor as far as I know. If they want to keep the transmitters humming, that's what I would advise them to do.
