Aside from what's already been mentioned, not that I know of. Motorola makes 2-frequency pagers, but no alpha.
For the RX only with weather, you could pick up a *tiny* Icom or Kenwood or Vertex portable that will do 12 channels or so. The Icom ones at least have page receive capability, and you could probably get one used for around $100.
The whole pager market mystifies me. Sure, Swissphone and Apollo make pagers that are pretty damn cool. But why haven't Icom/Kenwood/Vertex jumped in and made something to compete with big M? At $550 for a Minitor V, I'm sure they could make the same thing much cheaper. And why not go all out, use the receive circuitry from one of their portables (or even easier one of their ham/amateur radios)?
While we're talking pagers, a few things I've wanted for years:
1) A hybrid voice/alpha pager. Our dispatch gives the location of the call, why not have something like a Minitor V with an LCD screen in it that could scroll a message entered by the dispatcher (and sent along with the voice or tones)? Just enough text to get a message through, like call type, address, and time?
2) A pager with multiple channels. Yaesu (Vertex) made a ham portable that was the same size as a Minitor and did VHF/VHF UHF/UHF or VHF/UHF simultaneously with a transceiver and a second receive-only radio. So you could monitor one frequency and still get pages (if that were built in to a pager).
3) A pager that acknowledges pages. Your pager receives a page, it transmits back some ID code to say that it received it. Or, even better, to get rid of all those IAmResponding.com-style systems, or calling the desk, has a button to press to send back a "responding" signal. Sure, no antenna, no good transmit coverage, but that could be worked on...
