Hello marine radio engineers,

Recently bought a secondhand Sailor RT2048 that I want to use for
listening to local/national marine channels. I have a "quicklist" with
some programming sequences in "service mode" but this list isn't
complete.

Could anyone assist me with some more info on programming this radio ?
I would like it to function as a scanning receiver for as much
available marine channels as possible, with disabled transmit
function.

Is it correct I can make it a 200 channel receiver using the "US" mode
as a second set of 100 ?

Any info highly appreciated !!
Kindest Regards,
Paul
