R-35 is, of course, on the Corsair II.

On the 544, I'd change R-11 from 680 ohms to 4700 ohms, or C-3 from 33 to
47
ufd. Not both.
As Jerry said, on R-35, you can cut the ground foil run and bridge the gap
with a 4700 ohm.
These resistors can be 1/4 watt.
That should get you close.
Merry Christmas everyone!

On the Corsair II control board, it looks like increase C6 or R12
preferably R35 better than R12. C6 is 33 mfd, R35 is a 10K pot. Don't
have anything on hand for the 544, but its probably similar.

delay adjustment for CW in the rigs has narrow range - I would like to
slow the relay down a bit more..... suggestions to change circuitry for
