The left x-tal is not a FT-243, but similar and it can be used in a BC-620 with 79 channels, 100 kHz separated, in the range 20,0-27,9 MHz. These FT-243 x-tals are numbered after their channel, so channel no.65 means the fundamental frequency of 7873,3 kHz multiplied by 3 + the IF frequency of 2880 kHz, giving a working frequency of 26500 kHz.
The middle and right x-tals were used in the BC-659 and BC-1335 with 120 channels, 100 kHz separated, in the range 27,0-38,9 MHz. These x-tals are numbered after their working frequency, devided by 100, so channel 292 means the fundamental frequency of 6225 kHz multiplied by 4 + the IF frequency of 4300 kHz, giving a working frequency of 29200 kHz.
