This may be old news, but I noticed the other day after winds "adjusted" my antenna, that one can use the two LEDs that are visible through the top of the TU-HDS20 (front right corner) to determine if an OTA signal is detected (I'm guessing it's detecting the pilot). If the green LED is on by itself, the signal is detected and decoded. If the green and red LEDs are on, then the signal is there, but has too many errors to decode. The rate at which these two LED's flash on and off together (appears) to be proportional to the quality of the received signal (based on my observations while rotating the antenna). That is to say, the more time they are in the "on" state the greater chance of decoding the signal. I have not observed the red LED to be on by itself.


Best Regards,
