Symbiosis

[FWKnightship]

Challenge: find an RT 14 reflector in Symbiosis; that would be the lowest possible repeat time.

We already have a G to 12c/12 signal and 12c/12 signal to G (repeat time 14):

Just now, I found an FNG eater that allows for a repeat time of 39(note R49 doesn’t work at 39):

Also, 180° reflector:
