Hi, I'm using ft8code.exe from 2.7.0-rc6 on Windows, and the 2.7.0-rc6 source code
There is no -c * print*,'Program ft8code: Provides examples of message packing, ', &* * 'LDPC(174,91) encoding,' print*,'bit and symbol ordering, and other details of the FT8 protocol.' print* print*,'Usage: ft8code [-c grid] "message" # Results for specified message' print*,' ft8code -T # Examples of all message types'* * print*,' ft8code -t # Short format examples'* There is no '-c' option. It's presented to the user when they run ft8code.exe with no parameters, but that's it. Nowhere I can see in the source code attempts to read the -c argument. You'll find checks for '-T' and '-t' but none for '-c'. At best you'll encode "-c" as free text. Not sure if '[-c grid]' refers to an option in a previous version, moved to another program, or if it was included as an aspirational thing, but I'm pretty sure '-c' doesn't do anything in the current version of ft8code (or if it does I'd love to know how to trigger it) Not 100% sure what it's meant to do, but the easy fix is just to remove the text " [-c grid]". Cheers, Peter ("Pengo Wray") VK3PGO
