Yes, the Amateur Service is the primary (and exclusive) user for the 2M band. However, I believe that anyone can use any frequency they want provided that the ERP is less than something like 100mW. (Don't quote me on this, but I think there is such an exception). Of course, even a low-radiation signal like that, if close enough (like utility lines) will be easily heard in our receivers.
Also, we seem to have entered an era in which anyone can violate any FCC regulation they want, as long as nobody complains and they don't get caught. We are experiencing intrusions of all nature, especially from consumer electronics and major appliances at levels never before seen. Watch what happens to your HF bands when you get around to replacing your washer/dryer with one of the new, state-of-the-art microprocessor-controlled units. There is no RF suppression whatsoever, and it comes right out through the front display panel. Prey, prey to the powers that be, that your neighbors never buy a Toshiba large screen TV!!! I can't speak for their flat panels, but their rear projections sets could qualify as HF transmitters!!
I'll continue to listen and keep a log as well.

Is that permissible at that frequency? Are we not Primary users in the 2m band?
My local utility, Florida Pop and Flash, (sorry Florida Power and Light), use 70cm for their telemetry.

It wouldn't surprise me in the least to discover that it was from a utility. Brighthouse Networks transmit a signal on 145.25 to use for cable plant locating. Of course it radiates, and if you have cable in the neighborhood, you'll hear that too.

If its of any interest, I too hear it all the way down here in EL96 (between Naples and Fort Myers) and I have heard it on past occasions.

Hi Scott,
I'm not hearing anything on 145.800 at this time (Saturday evening, 19:35
EDT), but there is something on 145.807500 (+/- 150 Hz). I'll keep listening
to
see if this situation changes and post here with any results I get.

Hi All:
Anyone hearing packet on the ISS voice downlink frequency 145.800? Been hearing it here for quite a while, curious if anyone else is hearing it,
and
can maybe decode some and get a callsign? I don't think it's real local,
but
it's definitely there in Melbourne.
Thanks
