25695 kHz AM 25.695 MHz AM - coming in nicely on multiple receivers on the US East Coast.  OMs and YL heard, likely the YL is the dispatcher and the OMs are the drivers. 

There are other active frequencies in the 25 MHz and 26 MHz low channels this afternoon but this one is (at least at the moment) the strongest in the 25 MHz band.  I've logged it several times in the past, likely with the same user.

As to be expected, 26.585 MHz AM and the nearby frequencies are also busy with Mexican stations (on 26585 anyway).
