Your system is fine and you can stop scratching.  This is an anomaly only on 
FO-20 (FO-29 does not exhibit this behavior).  I have measured it 
consistently at +47 kHz as the "repeating" frequency.  In other words, if 
your uplink is heard at 435.840, it will also be heard at 435.847 MHz, but 
about 6 dB lower in strength.
