if I remember correctly from my amateur radio days, this is a
sign that the input section isn't correctly "tuned in": the carrier
frequency isn't exactly 465KHz.
This is true for Chao(Exceed) Wai(External) Cha (Differneial) receivers.
For Lai(come) Fu(as FuDan University) receivers, the receiver is
tuned to the lower band of the broadcasting (so that part of the
RF signal is missing when going through the LC filter).
Sorry I cannot type in Chinese and I don't know those terminologies in
English
