I just picked up an old Motorola Alert Monitor (found at the local town recycling/transfer station). There's no ID plate anymore on the back, but from lots of investigation it is a VHF High model. It is also a 12vdc model with the DC cord. It works well, very clean inside. There doesn't seem to be a lot of info on the 'net on these, but I did confirm the xtal freq is: 158.790. Which is interesting because that was never (to my knowledge) a local freq here in Rensselaer county I think that was a Washington County EMS freq at one time. You can sometimes put together a story from these items that you find: the 12vdc cord was neatly wound up, looked like it was stored for a while from the dust, probably someone's dad or grandpa that used to be a FF or EMT, no doubt was in their vehicle, etc. There were some other old scanners in that same pile so I suspect someone's dad or grandpa passed away and his old stuff got thrown away
Is there a good source of crystals for these units anymore? It's been a while since I ordered crystals, I read on some other posts that crystal mfr's don't want to sell just a handful anymore, really expensive. Any old hints and tips from the old timers here on RR are always appreciated.
