Dissappearing locator

[K0AY]

I have reinstalled L4OM. Under my location, I enter FN20. I hit the save button and setup disappears. When I reopen it, the My locator field is both blank and red. How do I fix this?

have you tried the 6 digit locator for your location?

Thanks again Terry. I was put off from putting in 6 digits as the red colour went away after 4 digits but reappears when the 5th is entered, so I was discouraged from going any further.

Yes, because 4 is good. 5 is incomplete, 6 is good while 7 is again incomplete
