Maine DOT heard recently

[mainetrunk]

During the past 8 month's, I have been listening for DOT simplex freqs..
Here is what I have caught and confirmed..
They were using different channels for different jobs..
47.100 -- dc 205.. WAS quiet til recently
47.340 -- 100.0
47.340 -- 88.5
47.220 -- 179.9 heard while they were road painting
Hopefully they got rid of all the csq channels and added tones..
Csq stinks for monitoring, especially lo-band

I forgot 1

They also use 47.340 PL 167.9 for simplex and to talk to Augusta..
I believe they called the simplex version channel 3,
and to talk to Aususta is ch-4
47.100 - dc 205 has been checking in today regularly
I have heard voices on it in simplex, but today I am getting all kinds of signal strength when they key up..
And there are many key ups
