several levels of frequency shift in say 1Hz and just learn a new visual

Good idea for strong signals Andy, but for the task in hand you would need to
accurately position them between interfering Loran spurs. Also a 7Hz wide
signal would seem to be outside the 2Hz across the screen currently necessary
for Larry to see a 500mW signal from the UK.
But, if the resulting tone sequence from your receiver could be automatically
decoded into a character on the screen........
