Dude selling this on Facebook. Looks cool. You can record messages for playback over the air. He has a video of it broadcasting weather conditions. I imagine popo and REACT used them.
I've never seen one.

road maintence crew has one here,,, PAIN IN TH A@@ every 2 minutes doing a 1 minute message that really has no meaning all night long on channel 19,, and gives out a so large signal they bound to be running a 2 pill or bigger with it,,,, damn thing has been called about to tallahassee so many times but will pop up on the turnpike or other toll roads,,,,
Is it legal?
I'm guessing not, unless it automatically yields to emergency traffic or has an operator at all times.

Modified for low power on a quiet channel, these are great for fox hunts. If not, forget about all the auto functions. You can still use it like a regular CB. Just turn the mode switch to STD CB...done. Perfectly legal.
Antenna Test Range
1). Fixed location
2). Fixed output
— One makes use of it while mobile driving both towards and away. Distance, Intelligibility, Compass Heading Changes, etc.
Had one awhile back on a Florida turnpike just north of a metro area. Useful. Six or eight passes (three or four round-trips over as many days).
A). Can I pick it up farther out using pre-amp? (yes).
B). Qualify the latest scheme in noise abatement? (yes).
C). Ask other drivers how far out they’re receiving (mile marker?).
D). Changes between day & night? (yes)
E). Weather influences (can’t tell).
F). Difference in antennas (yes).
All for the low price of some diesel.
Could first hear it 25-27/miles out with cab-mount cophase pair at night— then a null with truck on an off-heading a number of miles — and very clearly after 15-mile marker reached when back on original heading.
In opposite direction lost signal earlier and only knew to listen for it due to notes made (53’ van).
Central Florida low population-density rural terrain made for consistency. The metro area to the south of the transmitter cancelled any real testing except at a few miles (intended reception range by FL DOT).

located it at the intersection of i 4 and rt 540a on the hill for the exit with a a99 mounted on about a 25 foot mast,, been very lucky that is hasnt been heard in a while,,,but been so many complaints made because we got the dot number in tallahassee and kept calling and spread the number around,,, channel 19 is a active channel here in central florida,,especially at night,, many many warehouses here and close to major intersections of highways,,, every 2 minutes with a 1 minute message just saying there may be a delay in a road,,, no no dont like it at all,,,
I agree that having an operator monitoring the station that could override the broadcast would be legal. I'm guessing there is rarely an operator around these when they are in use. Do they automatically cease broadcasting when a signal is received? Do they interrupt other transmissions?

The fcc changed the rules a while ago to allow a transmission to a non specific receiver. A general broadcast for highway safety was the intent. This rule change allows us to call CQ now also. I think this is what the truck stop down south uses because I hear their truck wash advertising when skip rolls in.
So yielding to emergency traffic is a thing of the past? Broadcasts for safety reasons has always been legal as far as I know.
I'd look it up, but legal or not they'll do it anyways.
Do they automatically cease broadcasting when a signal is received? No Do they interrupt other transmissions? Yes
The addition of an auto squelch controller that’s tied to the transmitter would stop transmission, but as far as I know, nothing like that is incorporated.
If I owned one of those units, my reflex speed at snatching a Phillips screwdriver would set a personal record. First I’d like to know what radio is actually being used. I’m guessing some slightly modified Uniden or Cobra model. Has anybody done a teardown analysis?
It would be fun to use it as a cb beacon but in reality I'm sure most people would use it illegally just to be annoying.
I've seen those a time or two. If you wanted to be a real jerk, you could whisper "I aint got no panties on" and set it to repeat it every 30 seconds. 
Wonder how much he wants for it?
