TDA7513

Field-strength Meter (Input at FMMIX2IN; fc = 10.7MHz, no mod) (antenna level = V67 – 49dB)

MPX output (output at TUNEROUT)

Field-strength Stop Station (Input at FMMIX2IN – fc = 10.7MHz, no mod) (antenna level = V69 – 49dB)

Soft Mute

ISS Filter (FMIF1AMP1 gain MUST be set to 14dB) *

* if ISS function is not used, SEEK must be set to “ON” in FM
