Default Ray-49e VHF receiver not receiving

Nautical VHF radio from Raymarine type 49e, Tx ok but no Rx.
Understand a possible cause might be linked to bad ceramic filters
I've located two ceramic filters marked "CQ M50FW".
Need help to find any information for replacement, as manufacturer,
data sheet, possible replacements type, etc.
Thanks


Any coloured dots on them?
Coincidence I just replaced a 10.7M one this afternoon, as easier than
hooking up an RF oscillator to test if failed FM receiver. Unfortunately
not the silver migration, ohmic problem ,something else around an LA1186
FM front end, all DC are correct by the schematic.
