Is MODOT still analog?...there not coming in lately ....I would expect them to go digital soon? They are on a repeater system are they not?

Most of the snow removal crews in the metro portion of the Kansas City district use simplex for truck-to-truck.
Because of some of the precipitation falling this afternoon, I've logged:
151.04000.........PL 123.0....heard truck out of Less Summit barn...heard truck on Stadium Drive....trucks out of the Nashua barn
151.07000.........PL 94.8....truck in Lees Summit area
151.07000.........PL 123.0....Independence area.....I-70 area out to Grain Valley
151.07000.........PL 167.9....Kansas City repeater (heard EOC requesting road report)
156.13500.........PL 94.8....heard truck near State line....another truck near Little Blue Pkwy
This frequency is one of the main channels used in the Northwest district, but seems to get some usage in the northern part of the Kansas City district:
151.13000.........PL 123.0....trucks in Liberty/Kearney area
Most of the Northwest district (St Joseph) uses 151.13 with a PL of 141.3. They seem to use the repeaters more than the Kansas City district. What little simplex traffic I've monitored uses the same 141.3 PL as the repeater outputs.
There may be more frequency/PL combinations. Most of the weather activity this afternoon appears to be south of the river.
When MODOT gang plows, they do not use their repeaters as the truck radios desense the repeater output and they cannot talk truck to truck so they go simplex or direct mode.
Desense?? What's that? You mean after spending a king's ransom on super-duper expensive equipment it is not perfect in all situations in all areas?

At last I know there are at least two of us who understand the concept and how it degrades communications. Now if we could only 'splain the fallacy of one-size-fits-all to the rest of the world...

Yep, and it only took them how many years to figure this out!
Someone had asked me the RF output level of their mobiles.
At one time, I'd been told by a local Motorola tech that maintained the St Louis MODOT radios that they were 100 watt radios.
.
A motorola tech who took care of MODOT radios? MODOT is self maintained.
Anyways, they have used LOTS of 45-50 watt radios, and still do. A large number of supervisors, and motorist assist units have MOSWIN radios, for interoperability, as do their interop trailers, but they are in addition to their regular VHF radios.
I am not aware of any MODOT operations that just use MOSWIN.
