Note: When two received frequencies have relationships per the equation below or other similar relationships, an internal heterodyne may be heard. This is not a defect.
2 (fU – 45.05) – 4 (fV + 38.85) = 38.85 or 45.05 (fU – 45.05) – 2 (fV + 38.85) = 38.85
n (fSV – 45.05) – n (fV + 38.85) = 38.85 or 45.05 where n = 3, 4, or 5. fV = VHF frequency (band A)
fU = UHF frequency (band B) fSV = VHF frequency (band B)
