Lancashire snow gritters - 87.200MHz - where have they gone?

[g8tzl2004]

For many years I have listened to the Lancashire snow gritters on low band 87.2000 and 87.1875 MHz.

Central South (West Lancs, Chorley, Preston) is on 87.2000 MHz

East (Burnley, Pendle) is on 87.1875 MHz

However, this year I have heard nothing even though the roads are being gritted

Have the gritters changed frequency (High Band VHF??) or are they now using mobile phones?

Any ideas?

Thanks

My area all use MDTs and mobiles so maybe the way they have gone.

Confirmed gone. All LB Kit removed from vehicles. Some LB antennas remain but thats it.
