There are quite a few indicators of Far East conditions audible using a car radio. This is good as when driving to your DX-QTH you can listen what´s the situation on AM band is. I am very pleased with my latest VW and it´s integrated receiver with real knob! A pity it has no switch to 10 kHz increments, so listening to TA is difficult. One of the Far East examples of usual stations is Korea on 1566 - if it is loud and clear (and not India) the conditions over the Northern Latitudes are better. Also 1170 is a good channel to check if the dominant is an European, the Philippines or Korea. An example of the Korean KBS can be heard here.
