HF Air Traffic can be hear on the following frequencies in
my ares (Maryland):

3494 khz. 6640 khz. 8933 khz. 11342 khz. 13330 khz. 17925 khz.


Correct me if I'm wrong but I think these are
LDOC (long distance operation coordination ?)

Back in pre-ssb days, a radiotelegrapher was part of an international flight
