[Premium-Rx] WJ-8617B INFO NEEDED

[Pat1McA at aol.com]

Greetings to all,
 
I am checking a WJ-8617B (S1) ver 6.319 radio recently out of  storage.
 
The BITE fails on (AM) - 04 F2 100 - and on (FM) - 35  F4 100 -.
 
Can anyone decode those numbers please and point me in the right  
direction? 
 
I suspect the BITE itself or an out of spec 100kHz roofing filter  
somewhere, not the 21.4 BW 100kHz filter (?). It passes all BITE  OK in CW.
 
All info gratefully received. Please contact offline. 
 
Thanks and regards,
