"For the red TX LED to flash instead of illuminate constantly **when
transmitting**". (Asterisks added for emphasis).

He did not say to have it flash continuously while in test mode ... only if
you tried to transmit.

I don't think this would annoy anyone but I have to agree with my old friend
KR2Q that using the VFO B display to report that you are in test mode only
you try to transmit might be the best solution as it would not preclude or
cover up anything meaningful on the display.
