kodera2tIt seems, no one on hackaday.com has interest on this type of hack, so I will close this project by this log.
FM detection circuit of C-111 consists of TK10420L, which is quite similar to MC3357.
By removing 10.245 MHz crystal and 455 kHz filter and bypassing FM detection block will make C-111 into SSB/CW receiver.
