They are duplex channels. Shore side transmits on one freq, boat side on
another. Both can talk at once.

I was testing my radios by talking back an forth thru each channel. On
channels 24 thru 28 and 84 thru 87 the radios do not respond to each other.
Is this what you would expect ?

I notice these are public correspondance channels are the marine operators
no longer in business? Are these channels ever used anymore?
